  • Android - Add other values to websettings settextsize

    - by user1681477
    In my application I am using a webview, and in order to increase/decrease text size, I am using WebSettings().setTextSize method, but, this method is limited to 5 predefined enum sizes only (SMALLEST, SMALLER, NORMAL, LARGER,LARGEST). I know I can use WebSettings().setTextZoom(int), but my application is available for API Level 8 and above, and this method was introduced in API Level 14... My question is: Is there any way to add other sizes to webSettings().setTextSize? maybe by extending textSize enum, or define other sizes?

  • Rendering CALayer in context uses large amounts of memory

    - by Otium
    I am taking a snapshot of a UIWebView layer, but when I render the webview's layer in the current context my app uses 10mb more memory, and I don't think that should be right. Here is my current code: CGSize imageSize = self.bounds.size; UIGraphicsBeginImageContextWithOptions(imageSize, YES, 0); CGContextRef context = UIGraphicsGetCurrentContext(); [self.layer renderInContext:context]; _snapshot = UIGraphicsGetImageFromCurrentImageContext(); UIGraphicsEndImageContext();

  • Fosfor EPUB Reader

    - by Geertjan
    Instead of creating a fullblown NetBeans Platform application for doing WYSIWYG editing for EPUB, similar to Sigil, I decided to focus purely on the very narrow scope of EPUB reading. The scope is narrower and, since the application will be a lot less ambitious and smaller, a pure JavaFX implementation makes sense. When you somehow get, e.g., buy, an EPUB file, you typically read it on a tablet or mobile device. However, some people in the world, e.g., me, still have laptops. Therefore, I'm creating a small JavaFX application that unzips EPUB files, into a temp directory, and then loads them into a JavaFX WebView. Arabic support: For an application like this, simplicity is the most important thing. Very few buttons, very few options, preferably no configuration of anything. Just let the user open the EPUB file and read it, that's it, nothing fancy. CSS stylesheets and images are correctly read. It's exactly what it looks like, a reader for EPUB files. The back and forward buttons are working and you can also switch to the table of contents. When it is complete, which it pretty much is right now, publishers of EPUB files can make this small app available from their site, to simplify life for their readers, since it will run easily and well on all operating systems.

  • Live HTML Preview

    - by netbeanstips
    When you need to edit an HTML document in NetBeans you may find useful this little plugin that adds a Preview tab to HTML editor window. The plugin works with some small issues in NetBeans 7.4 but I recommend using development builds instead. So install the plugin, restart NetBeans and open any HTML document. Notice there's a Preview button in editor's toolbar (see the red rectangle in the picture below). Now split the editor window by dragging the split button at top right corner. You can also use menu View - Split - Vertically.  Then in the bottom split part toggle Preview button. You will get a live preview of your HTML source code. The preview pane will auto-refresh as you edit the HTML code. There are even some handy tools in Preview toolbar, for example you can resize the preview browser to match the screen dimensions of various device types. I know there is full-blown HTML5 support in NetBeans 7.4. But if you need to edit a single document or when you're running Java-only NetBeans distribution this plugin may come handy... Note: The plugin is built on top of embedded WebKit browser which is based on JavaFX WebView component. So there might be some issue when using the plugin on some flavors of Linux.

  • Iphone: controlling text with delay problem with UIWebView

    - by James B.
    Hi, I've opted to use UIWebView so I can control the layout of text I've got contained in a local html document in my bundle. I want the text to display within a UIWebView I've got contained within my view. So the text isn't the whole view, just part of it. Everything runs fine, but when the web page loads I get a blank screen for a second before the text appears. This looks really bad. can anyone give me an example of how to stop this happening? I'm assuming I have to somehow hide the web view until it has fully loaded? Could someone one tell me how to do this? At the moment I'm calling my code through the viewDidLoad like this: [myUIWebView loadRequest: [NSURLRequest requestWithURL:[NSURL fileURLWithPath:[[NSBundle mainBundle]pathForResource:@"localwebpage" ofType:@"html"] isDirectory:NO]]]; Any help is much appreciated. I've read round a few forums and not seen a good answer to this question, and it seems like it recurs a lot as an issue for beginners like myself. Thanks for taking the time to read this post! UPDATED info Thanks for your response. The suggestions below solves the problem but creates a new one for me as now when my view loads it is totally hidden until I click on my toggle switch. to understand this it's maybe most helpful if I post all my code. Before this though let me explain the setup of my view. I've got a standard view within which I've also got two web views, one on top of the other. each web view contains different text with different styling. the user flicks between views using a toggle switch, which hides/reveals the web views. I'm using the web views because I want to control the style/layout of the text. Below is my full .m code, I can't figure out where it's going wrong. My web views are called oxford & harvard I'm sure its something to do with how/when I'm hiding/revealing views. I've played around with this but can't seem to get it right. Maybe my approach is wrong. A bit of advice ironing this out would be really appreciated: @implementation ReferenceViewController @synthesize oxford; @synthesize harvard; // Implement viewDidLoad to do additional setup after loading the view, typically from a nib. - (void)viewDidLoad { [super viewDidLoad]; [oxford loadRequest: [NSURLRequest requestWithURL:[NSURL fileURLWithPath:[[NSBundle mainBundle]pathForResource:@"Oxford" ofType:@"html"] isDirectory:NO]]]; [harvard loadRequest: [NSURLRequest requestWithURL:[NSURL fileURLWithPath:[[NSBundle mainBundle]pathForResource:@"Harvard" ofType:@"html"] isDirectory:NO]]]; [oxford setHidden:YES]; [harvard setHidden:YES]; } - (void)webViewDidFinishLoad:(UIWebView *)webView { if([webView hidden]) { [oxford setHidden:NO]; [harvard setHidden:NO]; } } //Toggle controls for toggle switch in UIView to swap between webviews - (IBAction)toggleControls:(id)sender { if ([sender selectedSegmentIndex] == kSwitchesSegmentIndex) { oxford.hidden = NO; harvard.hidden = YES; } else { oxford.hidden = YES; harvard.hidden = NO; } } - (void)didReceiveMemoryWarning { // Releases the view if it doesn't have a superview. [super didReceiveMemoryWarning]; // Release any cached data, images, etc that aren't in use. } - (void)viewDidUnload { [super viewDidUnload]; // Release any retained subviews of the main view. // e.g. self.myOutlet = nil; } - (void)dealloc { [super dealloc]; [oxford release]; [harvard release]; } @end

  • Setting custom UITableViewCells height

    - by Vijayeta
    I am using a custum UITableViewCell which has some labels, buttons and imageviews to be displayed. There is one label in the cell whose text is a NSString object and the length of string could be variable. Due to this, I cannot set a constant height to the cell in the UITableViews: heightForCellAtIndex method. The cell's height depends on the labels height which can be determined using the NSStrings sizeWithFont method. I tried using it, but it looks like I'm going wrong somewhere. How can it be fixed? Here is the code used for initializing the cell. if (self = [super initWithFrame:frame reuseIdentifier:reuseIdentifier]) { self.selectionStyle = UITableViewCellSelectionStyleNone; UIImage *image = [UIImage imageNamed:@"dot.png"]; imageView = [[UIImageView alloc] initWithImage:image]; imageView.frame = CGRectMake(45.0,10.0,10,10); headingTxt = [[UILabel alloc] initWithFrame: CGRectMake(60.0,0.0,150.0,post_hdg_ht)]; [headingTxt setContentMode: UIViewContentModeCenter]; headingTxt.text = postData.user_f_name; headingTxt.font = [UIFont boldSystemFontOfSize:13]; headingTxt.textAlignment = UITextAlignmentLeft; headingTxt.textColor = [UIColor blackColor]; dateTxt = [[UILabel alloc] initWithFrame:CGRectMake(55.0,23.0,150.0,post_date_ht)]; dateTxt.text = postData.created_dtm; dateTxt.font = [UIFont italicSystemFontOfSize:11]; dateTxt.textAlignment = UITextAlignmentLeft; dateTxt.textColor = [UIColor grayColor]; NSString * text1 = postData.post_body; NSLog(@"text length = %d",[text1 length]); CGRect bounds = [UIScreen mainScreen].bounds; CGFloat tableViewWidth; CGFloat width = 0; tableViewWidth = bounds.size.width/2; width = tableViewWidth - 40; //fudge factor //CGSize textSize = {width, 20000.0f}; //width and height of text area CGSize textSize = {245.0, 20000.0f}; //width and height of text area CGSize size1 = [text1 sizeWithFont:[UIFont systemFontOfSize:11.0f] constrainedToSize:textSize lineBreakMode:UILineBreakModeWordWrap]; CGFloat ht = MAX(size1.height, 28); textView = [[UILabel alloc] initWithFrame:CGRectMake(55.0,42.0,245.0,ht)]; textView.text = postData.post_body; textView.font = [UIFont systemFontOfSize:11]; textView.textAlignment = UITextAlignmentLeft; textView.textColor = [UIColor blackColor]; textView.lineBreakMode = UILineBreakModeWordWrap; textView.numberOfLines = 3; textView.autoresizesSubviews = YES; [self.contentView addSubview:imageView]; [self.contentView addSubview:textView]; [self.contentView addSubview:webView]; [self.contentView addSubview:dateTxt]; [self.contentView addSubview:headingTxt]; [self.contentView sizeToFit]; [imageView release]; [textView release]; [webView release]; [dateTxt release]; [headingTxt release]; } textView = [[UILabel alloc] initWithFrame:CGRectMake(55.0,42.0,245.0,ht)]; this is the label whose height and width are going wrong.

  • iPad UIWebView PDF rendering is giving me weird visual artifacts

    - by ashwhite
    I am having some difficulty using a UIWebView to render PDF files on the iPad. Everything works fine in portrait mode, but turning the device to landscape produces strange visual quirkiness. Zooming in (but not out) even the slightest will correct it, but obviously that's not an ideal workaround. The issue occurs with any PDF file (I have tried several, all stored locally in the bundle, not retrieved from the web). I also created a clone of the project for iPhone, which seems to work just fine, so the problem is iPad-specific. The problem occurs both in the simulator as well as on a physical iPad. Screenshot http://dev.boxkite.net/images/ipad/ipad-pdf.png Code NSString* filePath = [[NSBundle mainBundle] pathForResource:@"test" ofType:@"pdf"]; NSData* data = [NSData dataWithContentsOfFile:filePath]; [self.webView loadData:data MIMEType:@"application/pdf" textEncodingName:@"UTF-8" baseURL:nil]; Thanks so much for your time.

  • how to handle iframes/frames dom in the iphone uiwebview

    - by user217428
    in (void) webViewDidFinishLoad: (UIWebView*)webView I inject some javascript to handle the iframes. e.g. stringByEvaluatingJavaScriptFromString: @"try { var document = window.document.getElementsByTagName('iframe')[0].contentWindow.document.getElementsByTagName('frame'); } catch (e) { alert (e.message); }" It tells me the iframes document is undefined. Actually I have tried to print all the properties of contentWindow of iframe, but it's totally empty. I know the webViewDidFinishLoad may be called several times for each frame load. But I can never get the iframe document. I thought there should be at least once all the iframes are ready. Could someone please tell me how to get the iframe document to process the dom in the uiwebview? Thanks

  • Video/audio streaming does not stop even if UIWebView is closed - iPad

    - by lostInTransit
    Hi I see this issue only on the iPad. The same things works as expected on the iPhone. I am opening the URL from my application in a UIWebView. If the URL is a normal web page, it works fine as expected. But if the URL is that of a remote video/audio file, the UIWebView opens the default player which is again good. Now when I dismiss the UIWebView (by clicking on the Done button on the player), the streaming doesn't stop and the audio/video keeps playing in the background (I cannot see it but it does keep playing in the background, can hear it). The UIViewController in which the webview was created is also dealloced (I put in a log statement in the dealloc method) but the streaming doesn't stop. Can someone please help me out on why this could be happening? And how can I stop the audio/video streaming when the UIWebView is closed? Thanks.

  • Correct way to load image into UIWebView from NSData object

    - by rustyshelf
    I have downloaded a gif image into an NSData object (I've checked the contents of the NSData object and it's definitely populated). Now I want to load that image into my UIWebView. I've tried the following: [webView loadData:imageData MIMEType:@"image/gif" textEncodingName:nil baseURL:nil]; but I get a blank UIWebView. Loading the image from the same URL directly works fine: NSURLRequest *request = [NSURLRequest requestWithURL:[NSURL URLWithString:imageUrl]]; [imageView loadRequest:request]; Do I need to set the textEncodingName to something, or am I doing something else wrong? I want to load the image manually so I can report progress to the user, but it's an animated gif, so when it's done I want to show it in a UIWebView. Edit: Perhaps I need to wrap my image in HTML somehow? Is there a way to do this without having to save it to disk?

  • UIWebView - get total height of contents using Javascript

    - by Emil
    Hey. I'm trying to use a UIWebView for displaying content higher than the screen of the iPhone, without needing to scroll in the webView itself. For that, I need a way to get the total document size, including the scrollable area. I have tried a number of different Javascript solutions: (document.height !== undefined) ? document.height : document.body.offsetHeight // Returns height of UIWebView document.body.offsetHeight // Returns zero document.body.clientHeight // Returns zero document.documentElement.clientHeight // Returns height of UIWebView window.innerHeight // Returns height of UIWebView -2 Can you think of any other way to do it? Thanks.

  • iPhone: How to read contents from UIWebView XML Document?

    - by David Conlisk
    Hi all. In my iPhone app I'm using a UIWebView to allow the user to browse to an XML document on a website. When the user has found the xml document they want, they click a button below the UIWebView. Then I try to read the contents of the XML document from the UIWebView using: NSString *xml = [webView stringByEvaluatingJavaScriptFromString:@"document.getElementByTagName('rootXmlNodeName')[0].innerHTML"]; This doesn't work for me for XML documents. It works fine in a HTML page, e.g. using "html" for the rootXmlNodeName in the code snippet above. Any ideas? Thanks in advance!

  • UIWebView/MPMoviePlayerController and the "Done" button

    - by David Sowsy
    I am using the UIWebView to load both streaming audio and video. I have properly set up the UIWebView delegate and I am receiving webViewDidStartLoading and webViewFinishedLoading events perfectly. The webview launches a full screen window (likely a MPMoviePlayerController) Apple's MoviePlayer example gets the array of Windows to determine which window the moviePlayerWindow is for adding custom drawing/getting at the GUI components. I believe this to be a bad practice/hack. My expectation is that I should be able to figure out when that button was clicked by either a delegate method or an NSNotification. It may also be the case that I have to poke around subviews or controllers with isKindOf calls, but I don't think those are correct approaches. Are my expectations incorrect, and if so, why? What is the correct way to bind an action to that "Done" button?

  • How can I tell when a UIWebView has finished drawing to a context?

    - by phopkins
    In my code I'm trying to show a UIWebView as a page is loading, and then, when it's done, capture an image from the web view to cache and display later (so I don't have to reload and render the web page). I have something along the lines of: CGContextRef context = CGBitmapContextCreate(…); [[webView layer] renderInContext:context]; CGImageRef imageRef = CGBitmapContextCreateImage(context); UIImage *image = [UIImage imageWithCGImage:imageRef]; The problem I'm running into is that, due to UIWebView's tiling, sometimes only half of the page is rendered to the context by the time I capture the image. Is there a way to detect or block on UIWebView's background rendering thread so that I can get the image only after all of the rendering has finished?

  • How to make QT support HTML 5 database?

  • How to incorporate WebSockets into a Cocoa application

    - by robw
    I am developing a Cocoa application which involves a chat element. One approach I've considered is using Websockets to handle client-server communication. This would be particularly desirable because chats will also be displayed on a website, and using Websockets could make the implementation very simple. So: would it be possible to use a WebView element, and use Websockets within it? (I know Safari doesn't support Websockets yet, so I imagine this is not possible?) Failing that, are there any Websocket client libraries for C, Objective C, or any other language I could successfully embed within my application? Suggestions welcomed.

  • iPhone - Using javascritp to increase font of web view

    - by satyam
    i've a webview in my app. It has + and - buttons to increase and decrease the font. When I start the view, the text occupies whole 320 pixels width. I'm following the way mentioned in "http://stackoverflow.com/questions/589177/how-to-increase-font-size-in-uiwebview" I'm seeing the increase and decrease of font. But once the font size increases, text is not occupying full view. It won't occupy whole 320 pixels width. As and when text size increases, the width of final text in web view decreases slowly. Why? How to avoid it?
