  • outofmemoryerror when running jar but not when running in netbeans/ apache poi

    - by Laughy
    I basically have a program that filters records from one excel file to another excel file using the apache poi. My program runs fine when it runs using netbeans. However, upon doing a clean and build and double clicking the .jar file inside the dist folder, it runs for very long( too long!) and gives me the following error( that I got by running the program from command prompt ). Is there any work around for it? I have already increase the heap size to be -Xms1500m inside netbeans before cleaning and building. Exception in thread "AWT-EventQueue-0" java.lang.OutOfMemoryError: Java heap space at org.apache.xmlbeans.impl.store.Saver$TextSaver.resize(Saver.java:1592) at org.apache.xmlbeans.impl.store.Saver$TextSaver.preEmit(Saver.java:1223) at org.apache.xmlbeans.impl.store.Saver$TextSaver.emit(Saver.java:1144) at org.apache.xmlbeans.impl.store.Saver$TextSaver.emitElement(Saver.java:926) at org.apache.xmlbeans.impl.store.Saver.processElement(Saver.java:456) at org.apache.xmlbeans.impl.store.Saver.process(Saver.java:307) at org.apache.xmlbeans.impl.store.Saver$TextSaver.saveToString(Saver.java:1727) at org.apache.xmlbeans.impl.store.Cursor._xmlText(Cursor.java:546) at org.apache.xmlbeans.impl.store.Cursor.xmlText(Cursor.java:2436) at org.apache.xmlbeans.impl.values.XmlObjectBase.xmlText(XmlObjectBase.java:1455) at org.apache.poi.xssf.model.SharedStringsTable.getKey(SharedStringsTable.java:130) at org.apache.poi.xssf.model.SharedStringsTable.addEntry(SharedStringsTable.java:176) at org.apache.poi.xssf.usermodel.XSSFCell.setCellType(XSSFCell.java:755) at equity.EquityFrame_Updated.copyRowsFromOldToNew(EquityFrame_Updated.java:646) at equity.EquityFrame_Updated.init(EquityFrame_Updated.java:133) at equity.EquityFrame_Updated.createAndShowGUI(EquityFrame_Updated.java:71) at equity.EquityFrame_Updated.<init>(EquityFrame_Updated.java:50) at equity.FileOpener.generateButtonPressed(FileOpener.java:160) at equity.FileOpener.access$100(FileOpener.java:17) at equity.FileOpener$2.actionPerformed(FileOpener.java:61) at javax.swing.AbstractButton.fireActionPerformed(Unknown Source) at javax.swing.AbstractButton$Handler.actionPerformed(Unknown Source) at javax.swing.DefaultButtonModel.fireActionPerformed(Unknown Source) at javax.swing.DefaultButtonModel.setPressed(Unknown Source) at javax.swing.plaf.basic.BasicButtonListener.mouseReleased(Unknown Source) at java.awt.Component.processMouseEvent(Unknown Source) at javax.swing.JComponent.processMouseEvent(Unknown Source) at java.awt.Component.processEvent(Unknown Source) at java.awt.Container.processEvent(Unknown Source) at java.awt.Component.dispatchEventImpl(Unknown Source) at java.awt.Container.dispatchEventImpl(Unknown Source) at java.awt.Component.dispatchEvent(Unknown Source)

  • UIScrollView frame size issue in Landscape Mode

    - by viper15
    I'm trying to make UIScrollView auto-resize and appear correctly in Landscape mode. Portrait mode works fine. Here's my code: - (void)viewDidLoad { [super viewDidLoad]; //=== load all the custom view NSMutableArray *controllers = [[NSMutableArray alloc] init]; int page = 0; [controllers addObject:[self loadScrollView:[[Page1ViewController alloc] initWithNibName:@"Page1ViewController" bundle:nil] withPage:page++]]; [controllers addObject:[self loadScrollView:[[Page2ViewController alloc] initWithNibName:@"Page2ViewController" bundle:nil] withPage:page++]]; [controllers addObject:[self loadScrollView:[[Page3ViewController alloc] initWithNibName:@"Page3ViewController" bundle:nil] withPage:page++]]; self.viewControllers = controllers; [controllers release]; //=== automaticaly define number of pages _numberOfPages = [self.viewControllers count]; // a page is the width of the scroll view scrollView.autoresizingMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight; scrollView.pagingEnabled = YES; scrollView.contentSize = CGSizeMake(scrollView.frame.size.width * _numberOfPages, scrollView.frame.size.height); scrollView.showsHorizontalScrollIndicator = NO; scrollView.showsVerticalScrollIndicator = NO; scrollView.scrollsToTop = NO; scrollView.delegate = self; // First, set the number of pages pageControl.numberOfPages = _numberOfPages; pageControl.currentPage = 0; } Then, I went into each view controller nib file and set the background to different color to test if it's working. Unfortunately, when in Landscape mode, the width and height remains the same as in Portrait Mode. I'm not sure how to fix this problem. Hope anyone can help me. Many thanks in advance.

  • UIScrollView with pages enabled and device rotation/orientation changes (MADNESS)

    - by jbrennan
    I'm having a hard time getting this right. I've got a UIScrollView, with paging enabled. It is managed by a view controller (MainViewController) and each page is managed by a PageViewController, its view added as a subview of the scrollView at the proper offset. Scrolling is left-right, for standard orientation iPhone app. Works well. Basically exactly like the sample provided by Apple and also like the Weather app provided with the iPhone. However, when I try to support other orientations, things don't work very well. I've supported every orientation in both MainViewController and PageViewController with this method: - (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation { return YES; } However, when I rotate the device, my pages become quite skewed, and there are lots of drawing glitches, especially if only some of the pages have been loaded, then I rotate, then scroll more, etc... Very messy. I've told my views to support auto-resizing with theView.autoresizingMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight; But to no avail. It seems to just stretch and distort my views. In my MainViewController, I added this line in an attempt to resize all my pages' views: - (void)didRotateFromInterfaceOrientation:(UIInterfaceOrientation)fromInterfaceOrientation { self.scrollView.contentSize = CGSizeMake(self.scrollView.frame.size.width * ([self.viewControllers count]), self.scrollView.frame.size.height); for (int i = 0; i < [self.viewControllers count]; i++) { PageViewController *controller = [self.viewControllers objectAtIndex:i]; if ((NSNull *)controller == [NSNull null]) continue; NSLog(@"Changing frame: %d", i); CGRect frame = self.scrollView.frame; frame.origin.x = frame.size.width * i; frame.origin.y = 0; controller.view.frame = frame; } } But it didn't help too much (because I lazily load the views, so not all of them are necessarily loaded when this executes). Is there any way to solve this problem?

  • Rails3 and Paperclip

    - by arkannia
    Hi, I have migrated my application from rails 2.3 to rails3 and i have a problem with paperclip. I saw there was a branch for rails3 on paperclip git. So I added "gem 'paperclip', :git = 'git://github.com/thoughtbot/paperclip.git', :branch = 'rails3'" into the Gemfile and launch the command bundle install. Once paperclip installed, the upload worked fine but not the styles. I saw a hack to fix it. # in lib/paperclip/attachment.rb at line 293 def callback which #:nodoc: # replace this line... # instance.run_callbacks(which, @queued_for_write){|result,obj| result == false } # with this: instance.run_callbacks(which, @queued_for_write) end The styles are ok after that, but i'm not able to active the processor. My code is : has_attached_file :image, :default_url => "/images/nopicture.jpg", :styles => { :large => "800x600>", :cropped => Proc.new { |instance| "#{instance.width}x#{instance.height}>" }, :crop => "300x300>" }, :processors => [:cropper] My processor is located in RAILS_APP/lib/paperclip_processors/cropper.rb and contains : module Paperclip class Cropper < Thumbnail def transformation_command if crop_command and !skip_crop? crop_command + super.sub(/ -crop \S+/, '') else super end end def crop_command target = @attachment.instance trans = ""; trans << " -crop #{target.crop_w}x#{target.crop_h}+#{target.crop_x}+#{target.crop_y}" if target.cropping? trans << " -resize \"#{target.width}x#{target.height}\"" trans end def skip_crop? ["800x600>", "300x300>"].include?(@target_geometry.to_s) end end end My problem is that i got this error message : uninitialized constant Paperclip::Cropper The cropped processor is not loaded. Is anybody has an idea to fix that ? For information my application works fine on rails 2.3.4.

  • Redrawing rounded corners when using curvycorners-plugin for jQuery.

    - by timkl
    I'm using the curvycorners jQuery plugin (http://www.curvycorners.net/instructions/) to force IE to render rounded corners on divs. It works really well, apart from one thing: I have a validation error-message that pops up inside the div, using jQuery's "show" method. Curvycorners adds an extra div that is absolute positioned and has a set height, this means that you have to redraw the rounded corners if you want the containing div to resize when the error-message is shown. Curvycorners include a functions you can call to redraw the rounded corners, however it doesn't execute when I put it inside this click-function: $("input[type='submit']").click(function(e) { curvyCorners.redraw(); }); This is my markup: <fieldset class="curvyRedraw"> <legend>Some legend</legend> <form id="someForm"> <div id="error-message"></div> <div class="buttons"> <input type="submit" id="cancel" value="Cancel" name="action" /> <input type="submit" id="submit" value="Confirm" name="action" /> </div> </form> </fieldset> Anyone had similar issues?

  • iPhone Keyboard hiding fields in UIWebView

    - by Pete
    Hi, I am a beginner at iPhone development and am hoping someone can help me with my question. I have a UIWebView displaying a web page. If the user taps inside a textbox on the web page then the keyboard pops up. This is great, but it hides the field that the user tapped on. I have looked around and found code samples to deal with this, but none that specifically deal with the UIWebView. I have implemented UIKeyboardDidShowNotification and UIKeyboardDidHideNotification but am not sure how to resize the UIWebView properly. I have tried putting the UIWebView in a UIScrollView but not had any success with that. The code below seems to adjust the UIWebView but won't let it scroll to the field. -(void) keyboardDidShow: (NSNotification *)notif{ if (keyboardShown) return; NSLog(@"Keyboard Show"); NSDictionary *info = [notif userInfo]; NSValue *aValue = [info objectForKey:UIKeyboardBoundsUserInfoKey]; CGSize keyboardSize = [aValue CGRectValue].size; CGRect viewFrame = webBrowser.frame; viewFrame.size.height -= keyboardSize.height; webBrowser.frame = viewFrame; keyboardShown = YES; } -(void) keyboardDidHide: (NSNotification *)notif{ NSLog(@"Keyboard hide"); keyboardShown = NO; } Hopefully someone can help me or point me in the right direction. Thanks! Pete

  • JOGL Double Buffering

    - by Bar
    What is eligible way to implement double buffering in JOGL (Java OpenGL)? I am trying to do that by the following code: ... /** Creating canvas. */ GLCapabilities capabilities = new GLCapabilities(); capabilities.setDoubleBuffered(true); GLCanvas canvas = new GLCanvas(capabilities); ... /** Function display(…), which draws a white Rectangle on a black background. */ public void display(GLAutoDrawable drawable) { drawable.swapBuffers(); gl = drawable.getGL(); gl.glClear(GL.GL_COLOR_BUFFER_BIT | GL.GL_DEPTH_BUFFER_BIT); gl.glClearColor(0.0f, 0.0f, 0.0f, 0.0f); gl.glColor3f(1.0f, 1.0f, 1.0f); gl.glBegin(GL.GL_POLYGON); gl.glVertex2f(-0.5f, -0.5f); gl.glVertex2f(-0.5f, 0.5f); gl.glVertex2f(0.5f, 0.5f); gl.glVertex2f(0.5f, -0.5f); gl.glEnd(); } ... /** Other functions are empty. */ Questions: — When I'm resizing the window, I usually get flickering. As I see it, I have a mistake in my double buffering implementation. — I have doubt, where I must place function swapBuffers — before or after (as many sources says) the drawing? As you noticed, I use function swapBuffers (drawable.swapBuffers()) before drawing a rectangle. Otherwise, I'm getting a noise after resize. So what is an appropriate way to do that? Including or omitting the line capabilities.setDoubleBuffered(true) does not make any effect.

  • Custom GTK widget to bypass GTK layout engine?

    - by fret
    I have an application layer that I'd like to port to Gtk that has all it's own layout code and I don't really want to spend 'n' months re-writting it to work with the Gtk layout system, but rather just using the existing internal layout code and have Gtk render the resulting widgets. I've started by writting my own widget after trying several of the built in containers. Basically I'm looking for something like the GtkFixed container that doesn't have a minimum size, i.e. Gtk will fit the first widget to the entire window, and all the child widgets will lay themselves out so that they fill the area. If I use GtkFixed for that, the window is always limited to the size of the initial layout, as thats the "requested" space. I can't resize it smaller than that using the edges of the window decor. Maybe I need schooling in allocation vs requesting. My googling so far hasn't found the information I need to make this work. I did try. I'm using the C api at the moment, and I'm targetting Win32 and Linux. So far I have a shell app working in Win32 that puts up an empty window. But the first child widget is limiting the resizing to it's initial size.

  • UIImagePickerController does nothing when using camera after I hit "Use" button

    - by wgpubs
    Code below. When I hit the "Use" button after taking a picture ... the application becomes totally unresponsive. Any ideas what I'm doing wrong? The "addPlayer:" method is called when a button is pressed on the UIViewController's view. Thanks - (IBAction) addPlayers: (id)sender{ // Show ImagePicker UIImagePickerController *imagePicker = [[UIImagePickerController alloc] init]; imagePicker.delegate = self; // If camera is available use it and display custom overlay view so that user can add as many pics // as they want without having to go back to parent view if([UIImagePickerController isSourceTypeAvailable: UIImagePickerControllerSourceTypeCamera]) { imagePicker.sourceType = UIImagePickerControllerSourceTypeCamera; } else { imagePicker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary; } [self presentModalViewController:imagePicker animated:YES]; [imagePicker release]; } - (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info { // Grab original image UIImage *photo = [info objectForKey:UIImagePickerControllerOriginalImage]; // Resize photo first to reduce memory consumption [self.photos addObject:[photo scaleToSize:CGSizeMake(200.0f, 300.0f)]]; // Enable *PLAY* button if photos > 1 if([self.photos count] > 1) btnStartGame.enabled = YES; // Update player count label lblPlayerCount.text = [NSString stringWithFormat:@"%d", [self.photos count]]; // Dismiss picker if not using camera picker dismissModalViewControllerAnimated:YES]; }

  • iPhone SDK : UIImageView - Collapsing animation

    - by chris.o.
    Hi All, I'm trying to animating across the screen a horizontal bar with a color gradient. For simplicity, I chose to make a png of the fully extended bar, assign it to a UIImageView, and (attempt to) animate resizing of it using a UIView animation. The problem is that in the "closed" state of the Image, the portion of the image showing is not the part that I want. The image is arranged so that from L to R, a white to red color gradient occurs. The right side (about 20 pixels) is solid red and is the part I want to show when the bar is "collapsed". I'm trying to extend the image out by about 100 pixels to its full width. I referenced the "Buy Now" button example for my code as it seemed relevant" http://stackoverflow.com/questions/1669804/uibutton-appstore-buy-button-animation My code: [UIView beginAnimations:@"barAnimation" context:nil]; [UIView setAnimationDuration:0.6]; CGRect barFrame = bookBar.bounds; if (fExtendBar) { barFrame.origin.x -= 100; barFrame.size.width += 100; } else { barFrame.origin.x += 100; barFrame.size.width -= 100; } bookBar.frame = barFrame; [UIView commitAnimations]; I feel like this should be possible, maybe by setting an "offsetOfImage" to display in the UIImageView, but I can't seem to make it work. Also, I've noticed that the behavior is kind of consistent with what happens in Interface Builder when you resize an image. Then again, I would think there would be a way to override this behavior programmatically. Any suggestions (including other approaches) are welcome. Thanks, chris.o.

  • Internet Explorer 8 64bit and Selenium Not working.

    - by chobo2
    I am trying to get selenium tests to run. Yet every time I try to run a tests that should run IE I get a error on line 863 of htmlutils.js It says that I should disable my popup blocker. The thing is I went to IE tools- turn of popup block. So it is disabled and I get this error. Is there something else I need to disable. I actually don't even know what version of Internet explorer it is running since I am using Windows 7 Pro 64bit version. So when I do use IE I use 64bit version but I am under the understanding if the site or something like that does not support 64bit it goes to 32bit. So not sure what I need to do it to make it work. This is the lines where it does function openSeparateApplicationWindow(url, suppressMozillaWarning) { // resize the Selenium window itself window.resizeTo(1200, 500); window.moveTo(window.screenX, 0); var appWindow = window.open(url + '?start=true', 'selenium_main_app_window'); if (appWindow == null) { var errorMessage = "Couldn't open app window; is the pop-up blocker enabled?" LOG.error(errorMessage); throw new Error("Couldn't open app window; is the pop-up blocker enabled?"); } Where is this log.error message stored? Maybe I can post that too.

  • Rotating an Image in Silverlight without cropping

    - by Tim Saunders
    I am currently working on a simple Silverlight app that will allow people to upload an image, crop, resize and rotate it and then load it via a webservice to a CMS. Cropping and resizing is done, however rotation is causing some problems. The image gets cropped and is off centre after the rotation. WriteableBitmap wb = new WriteableBitmap(destWidth, destHeight); RotateTransform rt = new RotateTransform(); rt.Angle = 90; rt.CenterX = width/2; rt.CenterY = height/2; //Draw to the Writeable Bitmap Image tempImage2 = new Image(); tempImage2.Width = width; tempImage2.Height = height; tempImage2.Source = rawImage; wb.Render(tempImage2,rt); wb.Invalidate(); rawImage = wb; message.Text = "h:" + rawImage.PixelHeight.ToString(); message.Text += ":w:" + rawImage.PixelWidth.ToString(); //Finally set the Image back MyImage.Source = wb; MyImage.Width = destWidth; MyImage.Height = destHeight; The code above only needs to rotate by 90° at this time so I'm just setting destWidth and destHeight to the height and width of the original image.

  • autoresizingMask changes the size of the UILabel being drawn, just by being set

    - by Kojiro
    I have some custom UITableViewCells that are made programmatically as needed, I want these to resize. However, when I add autoresizingMasks to the UILabels in the cells, they all seem to stretch wider while anchoring to the left side. // This works fine UILabel *aField = [[UILabel alloc] initWithFrame:CGRectMake(60, 2, tableView.frame.size.width - 83, 21)]; UILabel *bField = [[UILabel alloc] initWithFrame:CGRectMake(60, 20, tableView.frame.size.width - 154, 21)]; UILabel *cField = [[UILabel alloc] initWithFrame:CGRectMake(0, 2, tableView.frame.size.width, 21)]; UILabel *dField = [[UILabel alloc] initWithFrame:CGRectMake(tableView.frame.size.width - 116, 11, 93, 21)]; UILabel *eField = [[UILabel alloc] initWithFrame:CGRectMake(tableView.frame.size.width - 116, 11, 93, 21)]; // But when I add this, it draws like the tableview is actually much wider than it really is aField.autoresizingMask = UIViewAutoresizingFlexibleWidth; bField.autoresizingMask = carrierField.autoresizingMask; cField.autoresizingMask = UIViewAutoresizingFlexibleWidth; dField.autoresizingMask = UIViewAutoresizingFlexibleLeftMargin; eField.autoresizingMask = priceField.autoresizingMask; So when the bottom section of code doesn't exist, everything works as expected, but when it does, a lot of the labels start falling off the right side or being stretched to where their centers are far to the right. Am I overlooking something simple?

  • animation extender in datalist control in asp.net 2008

    - by BibiBuBu
    Good Day! i have a question that how can i use animation extender in datalist control in asp.net with c#. i want the animation when i click the delete button (delete button will be in repeater). so that when i remove one record then it shows animation to bring the next record. it is in update panel. <cc1:AnimationExtender ID="AnimationExtender1" runat="server" Enabled="True" TargetControlID="btnDeleteId"> <Animations> <OnClick> <Sequence> <EnableAction Enabled="false" /> <Parallel Duration=".2"> <Resize Height="0" Width="0" Unit="px" /> <FadeOut /> </Parallel> <HideAction /> </Sequence> </OnClick> </Animations> </cc1:AnimationExtender> now if i put my button id in the Target control id then it gives error that it should not be in same update panel etc... but over all nothing working for animation. i am binding my datalist in itemDataBound....e.g. ImageButton imgbtn = (ImageButton)e.Item.FindControl("imgBtnPic"); Label lblAvatar = (Label)e.Item.FindControl("lblAvatar"); LinkButton lbName = (LinkButton)e.Item.FindControl("lbtnName"); Can somebody please suggest me something. thanks

  • Crystal Reports Programmatic Image Resizing... Scale?

    - by C. Griffin
    I'm working with a Crystal Reports object in Visual Studio 2008 (C#). The report is building fine and the data is binding correctly. However, when I try to resize an IBlobFieldObject from within the source, the scale is getting skewed. Two notes about this scenario. Source image is 1024x768, my max width and height are 720x576. My math should be correct that my new image size will be 720x540 (to fit within the max width and height guidelines). The ratio is wrong when I do this though: img = Image.FromFile(path); newWidth = img.Size.Width; newHeight = img.Size.Height; if ((img.Size.Width > 720) || (img.Size.Height > 576)) { double ratio = Convert.ToDouble(img.Size.Width) / Convert.ToDouble(img.Size.Height); if (ratio > 1.25) // Adjust width to 720, height will fall within range { newWidth = 720; newHeight = Convert.ToInt32(Convert.ToDouble(img.Size.Height) * 720.0 / Convert.ToDouble(img.Size.Width)); } else // Adjust height to 576, width will fall within range { newHeight = 576; newWidth = Convert.ToInt32(Convert.ToDouble(img.Size.Width) * 576.0 / Convert.ToDouble(img.Size.Height)); } imgRpt.Section3.ReportObjects["image"].Height = newHeight; imgRpt.Section3.ReportObjects["image"].Width = newWidth; } I've stepped through the code to make sure that the values are correct from the math, and I've even saved the image file out to make sure that the aspect ratio is correct (it was). No matter what I try though, the image is squashed--almost as if the Scale values are off in the Crystal Reports designer (they're not). Thanks in advance for any help!

  • iPhone Safari does not auto scale back down on portrait->landscape->portrait

    - by Tom
    Hi, I have a very simple HTML page with this META tag for the iPhone: <meta name="viewport" content="height=device-height,width=device-width,initial-scale=1.0,user-scalable=no" /> When the page loads in portrait mode it looks fine and the width fits the screen. When I rotate the iPhone to landscape mode the web page is auto resized to fit the landscape width. Good, this is what I want. But when I rotate back to landscape, the page is not resized back to fit the portrait width like it was before. It remains in the landscape width. I want the iPhone to set it back to the right width automatically, just like it did for the landscape mode. I don't think this should involve orientation listeners because it is all done automatically and I don't have any special styling for the different modes. Why doesn't the iPhone resize the web page back in portrait mode? How do I fix this? Thanks! Tom.

  • wpf - window to be tight round user control

    - by Andy Clarke
    Hi, I've got a user control that I'm loading into a Window dynamically - I wanted to set the Window so that it didn't have a size and then I thought the window to resize accordingly depending on the UserControl. However it dosn't - can anyone assist please? I've made a very basic example - I've cut out the dynamic bits and just put a UserControl in a Window. What do I need to do to get the window to be tight around the UserControl?

  • QWebView not loading external resources

    - by Nick
    Hi. I'm working on a kiosk web browser using Qt and PyQt4. QWebView seems to work quite well except for one quirk. If a URL fails to load for any reason, I want to redirect the user to a custom error page. I've done this using the loadFinished() signal to check the result, and change the URL to the custom page if necessary using QWebView.load(). However, any page I attempt to load here fails to pull in external resources like CSS or images. Using QWebView.load() to set the initial page at startup seems to work fine, and clicking any link on the custom error page will result in the destination page loading fine. It's just the error page that doesn't work. I'm really not sure where to go next. I've included the source for an app that will replicate the problem below. It takes a URL as a command line argument - a valid URL will display correctly, a bad URL (eg. DNS resolution fails) will redirect to Google, but with the logo missing. import sys from PyQt4 import QtGui, QtCore, QtWebKit class MyWebView(QtWebKit.QWebView): def __init__(self, parent=None): QtWebKit.QWebView.__init__(self, parent) self.resize(800, 600) self.load(QtCore.QUrl(sys.argv[1])) self.connect(self, QtCore.SIGNAL('loadFinished(bool)'), self.checkLoadResult) def checkLoadResult(self, result): if (result == False): self.load(QtCore.QUrl('http://google.com')) app = QtGui.QApplication(sys.argv) main = MyWebView() main.show() sys.exit(app.exec_()) If anyone could offer some advice it would be greatly appreciated.

  • Resizing and saving an image in WinMobile and .NET CF throws OutOfMemoryException

    - by devguy
    I have a WinMobile app which allows the user the snap a photo with the camera, and then use for for various things. The photo can be snapped at 1600x1200, 800x600 or 640x480, but it must always be resized to 400px for the longest size (the other is proportional of course). Here's the code: private void LoadImage(string path) { Image tmpPhoto = new Bitmap(path); // calculate new bitmap size... double width = ... double height = ... // draw new bitmap Image photo = new Bitmap(width, height, System.Drawing.Imaging.PixelFormat.Format24bppRgb); using (Graphics g = Graphics.FromImage(photo)) { g.FillRectangle(new SolidBrush(Color.White), new Rectangle(0, 0, photo.Width, photo.Height)); int srcX = (int)((double)(tmpPhoto.Width - width) / 2d); int srcY = (int)((double)(tmpPhoto.Height - height) / 2d); g.DrawImage(tmpPhoto, new Rectangle(0, 0, photo.Width, photo.Height), new Rectangle(srcX, srcY, photo.Width, photo.Height), GraphicsUnit.Pixel); } tmpPhoto.Dispose(); // save new image and dispose photo.Save(Path.Combine(config.TempPath, config.TempPhotoFileName), System.Drawing.Imaging.ImageFormat.Jpeg); photo.Dispose(); } Now the problem is that the app breaks in the photo.Save call, with an OutOfMemoryException. And I don't know why, since I dispose the tempPhoto (with the original photo from the camera) as soon as I can, and I also dispose the Graphics obj. Why does this happen? It seems impossible to me that one can't take a photo with the camera and resize/save it without making it crash :( Should I restor t C++ for such a simple thing? Thanks.

  • Auto-sizing and positioning in Flex

    - by Addsy
    I am working on a flex app that uses XML templates to dynamically create DisplayObjects. These templates define different layouts that can be used for each page of content in the app (ie , 2 columns, 3 columns etc etc). The administrator can select from one of these and populate each area with their content. The templates add one of 3 types of DisplayObject - HBox, VBox or a third component - LibraryContentContainer (an mxml component that is defined as part of the app) - which is effectively a canvas element with a TextArea inside. The problem that I am getting is that I need each of these areas to automatically resize to fit the length of the content but don't seem to be able to find an effective way to do so. In the LibraryContentContainer, when the value of the TextArea is set, I am calling .validateNow() on the LibraryContentContainer. I then set the height property on both the TextArea and LibraryContentContainer to match the textHeight property of the TextArea. In the following example, this is the LibraryContentContainer, viewer is the TextArea and the value property of the TextArea is bound to this.__Value. v is the variable containing the content for the textarea this.__Value = v; this.validateNow(); this.viewer.height = this.viewer.textHeight; this.height = this.viewer.height; This works to a degree in that the TextArea grows or shrinks depending on the length of content, but it's still not great - sometimes there are still vertical scrollbars even tho the size of the TextArea has grown. Anyone got any ideas? Thanks Adam

  • displaying images in a list box so the image resizes based on parent container

    - by MikeU
    I have an expander with a list box in it that displays image thumbnails. I want the images to be sized according to the size of the listbox and the list box to be sized based on the width of the expander. When I expand the expander I want the list box and the images to resize also. Does anyone know how I can accomplish this? <Expander Style="{DynamicResource ExpanderStyle}" Name="pictureExpander" IsExpanded="True" ExpandDirection="Left" Collapsed="pictureExpander_Collapsed" Expanded="pictureExpander_Expanded" Grid.Column="4"> <ListBox Name="photoList" ItemsSource="{Binding Source={StaticResource PhotoBin}}" IsSynchronizedWithCurrentItem="True" HorizontalAlignment="Stretch" ScrollViewer.CanContentScroll="False"> <ListBox.ItemContainerStyle> <Style TargetType="{x:Type ListBoxItem}"> <Style.Resources> <SolidColorBrush x:Key="{x:Static SystemColors.HighlightBrushKey}" Color="Yellow" /> </Style.Resources> <Style.Triggers> <Trigger Property="IsSelected" Value="True"> <Setter Property="BorderBrush" Value="Black"/> <Setter Property="BorderThickness" Value="5"/> </Trigger> </Style.Triggers> </Style> </ListBox.ItemContainerStyle> <ListBox.ItemTemplate> <DataTemplate> <Image Source="{Binding FileLocation}" Margin="0,5" HorizontalAlignment="Stretch" MouseLeftButtonDown="DragImage" /> </DataTemplate> </ListBox.ItemTemplate> </ListBox> </Expander>

  • Programmatic skins in Flex

    - by Flexer
    Hi, I am having 2 problems creating programmatic skin for Canvas. First problem: I would like to have background with rounded corners and I am using GraphicsUtil.drawRoundRectComplex in order to have round corners for only the upper two corners. The problem is that drawRoundRectComplex takes for each corner one single parameter - the corner radius. However my scaleX and scaleY factors are different and in fact the corners are not properly rounded because I either can set the radius using scaleX or scaleY. Graphics.drawRoundRect is better because it takes two parameters for the corners - elipse width and height and then you could apply both scale factors but it doesn't allow me to specify different radius for different corners. I am looking for an idea how to use GraphicsUtil.drawRoundRectComplex when scaleX and scaleY are different. Second problem: Even though I set my programmatic skin through style - < the skin's updateDisplayList gets executed only once and after that somehow "backgroundImage" style gets "undefined" and my programmatic skin is not associated anymore to the Canvas instance. As a workaround I am setting on each resize event "backgroundImage" style again but this is ugly. What could cause such "silent" resetting of the "backgroundImage" style to undefined? Thanks!

  • Problem with dynamic create tabPages in Winforms TabControl

    - by mirt
    I want to create dynamic tabPages in TabControl. In each tabPage I create dataGridView and i want to fill the entire space of each tabPage with this dataGrid. Here is code, where i do this: private void tabControlMutants_SelectedIndexChanged(object sender, EventArgs e) { DataGridView dgw = new DataGridView(); DataGridViewTextBoxColumn testCaseCol = new System.Windows.Forms.DataGridViewTextBoxColumn(); DataGridViewTextBoxColumn resultCol = new System.Windoows.Forms.DataGridViewTextBoxColumn(); // // dataGridView1 // dgw.ColumnHeadersHeightSizeMode = System.Windows.Forms.DataGridViewColumnHeadersHeightSizeMode.AutoSize; dgw.Columns.AddRange(new System.Windows.Forms.DataGridViewColumn[] { testCaseCol, resultCol}); dgw.Location = new System.Drawing.Point(3, 3); dgw.Name = "dataGridView1"; dgw.AutoSize = true; dgw.Dock = System.Windows.Forms.DockStyle.Fill; dgw.TabIndex = 0; // // TestCaseColumn // testCaseCol.AutoSizeMode = System.Windows.Forms.DataGridViewAutoSizeColumnMode.Fill; testCaseCol.HeaderText = "Test Case"; testCaseCol.Name = "TestCaseColumn"; // // ResultColumn // resultCol.HeaderText = "Result"; resultCol.Name = "ResultColumn"; tabControlMutants.TabPages[(sender as TabControl).SelectedIndex].Controls.Add(dgw); ((System.ComponentModel.ISupportInitialize)(dgw)).EndInit(); //fill dataGridView } But it doesn't work, becouse when i resize the main window, data gridView doesn.t change its size (although the dock property is set to fill). Any ideas?
