  • Printing complex widgets in Qt

    - by Jens
    I have a complex widget with tons of different subwidgets, e.g. subclasses of QLabel. I want to print this widget, but obviously I do not want to print the background, I want to print with differing text colors or have the style of frames slightly modified. As I do not really want to iterate through all subwidgets with a special "print" function, which I would need to attach to all widgets (how to add "print" to a QLabel?), I would like to use paintEvent. If I have a hierarchy MyWidget - derived from - some QWidget, I would like to insert a sublayer MyWidget - MyPrintWidget - some QWidget, where myPrintWidget::paintEvent would check, if the current print is going to the screen (thus call QWidget::paintEvent), else if we are printing to the printer, call some function MyPrintWidget::drawWidget instead. Is this the right way to print-enable a widget? How can I figure out in paintEvent, that I'm printing to a printer instead of the screen? Is there a good example of printing complex widgets?

  • detect if extended desktop is to the left or to the right

    - by bobobobo
    So, I have a screen capture utility (it takes full screen shots and saves it to png files) I've written, and it uses SM_CXVIRTUALSCREEN and SM_CYVIRTUALSCREEN to determine the width and height of the desktop. I then get the desktop DC and copy out the bits and save them as png. BitBlt( backDC, 0, 0, backBufferCX, backBufferCX, desktopDC, X_SRC, 0, SRCCOPY ); Here X_SRC is usually 0, UNLESS THE DESKTOP HAS BEEN EXTENDED "TO THE LEFT". In that case it needs to be -1280px, for example, if the left monitor measures 1280px. How can I determine if the desktop's starting point is negative (if the user has extended his desktop to the left?)

  • JPanels, JFrames, and Windows, Oh my!

    - by Jonathan
    Simply stated, I am trying to make a game I am working on full-screen. I have the following code I am trying to use: GraphicsEnvironment ge = GraphicsEnvironment.getLocalGraphicsEnvironment(); GraphicsDevice gs = ge.getDefaultScreenDevice(); if(!gs.isFullScreenSupported()) { System.out.println("full-screen not supported"); } Frame frame = new Frame(gs.getDefaultConfiguration()); Window win = new Window(frame); try { // Enter full-screen mode gs.setFullScreenWindow(win); win.validate(); } Problem with this is that I am working within a class that extends JPanel, and while I have a variable of type Frame, I have none of type Window within the class. My understanding of JPanel is that it is a Window of sorts, but I cannot pass 'this' into gs.setFullScreenWindow(Window win)... How should I go about doing this? Is there any easy way of calling that, or a similar method, using a JPanel? Is there a way I can get something of type Window from my JPanel? - EDIT: The following method changes the state of JFrame and is called every 10ms: public void paintScreen() { Graphics g; try{ g = this.getGraphics(); //get Panel's graphic context if(g == null) { frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); frame.setExtendedState(frame.getExtendedState()|JFrame.MAXIMIZED_BOTH); frame.add(this); frame.pack(); frame.setResizable(false); frame.setTitle("Game Window"); frame.setVisible(true); } if((g != null) && (dbImage != null)) { g.drawImage(dbImage, 0, 0, null); } Toolkit.getDefaultToolkit().sync(); //sync the display on some systems g.dispose(); } catch (Exception e) { if(blockError) { blockError = false; } else { System.out.println("Graphics context error: " + e); } } } I anticipate that there may be a few redundancies or unnecessary calls after the if(g==null) statement (all the frame.somethingOrOther()s), any cleanup advice would be appreciated... Also, the block error is what it seems. I am ignoring an error. The error only occurs once, and this works fine when setup to ignore the first instance of the error... For anyone interested I can post additional info there if anyone wants to see if that block can be removed, but i'm not concerned... I might look into it later.

  • [Android] Weird black line on top of list view

    - by CaseyB
    I am creating a layout with a ListView and at the very top of the list there is this weird black line that I can't seem to figure out how to get rid of! It's part of the ListView because it moves up and down as I size the ListView. Has anyone ran into this before? I couldn't get DDMS to take a screen capture for some reason so I took a picture of the screen with my G1, so please forgive the quality! As you can see the line is there at the top of the fade out in the list.

  • Windows API Programing....

    - by vs4vijay
    Hello There... Its me Vijay.. I m Trying to make a CrossHair(some kind of cursor) On The Screen while running a Game (Counter Strike)... so i did this... ############################# #include<iostream.h> #include<windows.h> #include<conio.h> #include<dos.h> #include<stdlib.h> #include<process.h> #include <time.h> int main() { HANDLE hl = OpenProcess(PROCESS_ALL_ACCESS,TRUE,pid); // Here pid is the process ID of the Game... HDC hDC = GetDC(NULL); //Here i pass NULL for Entire Screen... HBRUSH hb=CreateSolidBrush(RGB(0,255,255)); SelectObject(hDC,hb); POINT p; while(!kbhit()) { int x=1360/2,y=768/2; MoveToEx(hDC,x-20,y,&p); LineTo(hDC,x+20,y); SetPixel(hDC,x,y,RGB(255,0,0)); SetPixel(hDC,x-1,y-1,RGB(255,0,0)); SetPixel(hDC,x-1,y+1,RGB(255,0,0)); SetPixel(hDC,x+1,y+1,RGB(255,0,0)); SetPixel(hDC,x+1,y-1,RGB(255,0,0)); MoveToEx(hDC,x,y-20,&p); LineTo(hDC,x,y+20); } cin.get(); return 0; } #################################### it works fine....at desktop i see crosshair...but my problem is that when i run game...the cross here got disappeared.... so i think i did not handle the process of game... so i pass the HANDLE to the GetDC(hl)... But GetDC take only HWND(Handle To Window)... so i typecast it like this... HWND hl = (HWND)OpenProcess(PROCESS_ALL_ACCESS,TRUE,pid); and passed hl to the GetDC(hl)... but it doesnt work...Whats wrong with the code... plz tell me how do i make a simple shape at the screen on a process or game... PS : (My Compiler Is DevCPP and OS WinXP SP3....)

  • XNA how to organize code with game components (managers)

    - by Johannes
    XNA If I have a button class, and I have a buttonManager class that manages what buttons to be drawn to the screen depending on what the current game state is (main menu, in game, etc), how do I organize my code so that when I click on a button, it takes the user to a different screen. (ex. options menu, ingame). To be more specific, if I were to put the check to see if the user clicks on the button within the buttonManager how would I have the game switch and run the actual game (which is in an entire different class)? Main gameclass buttonManager game component (adds buttons) Button class

  • how do i keep the aspect ratio on image buttons in android?

    - by clayton33
    i have 5 square ImageButtons that i want to have lined up side by side on the bottom of the screen. I have each one set (different id's) as: <ImageButton android:id="@+id/box1" android:layout_width="fill_parent" android:layout_height="wrap_content" android:layout_gravity="center" android:adjustViewBounds="true" android:scaleType="fitXY" android:layout_weight="1" android:layout_margin="1dp" /> and i have the background assigned in main java like this: int[] imageIds = new int[] {R.id.box1,R.id.box2,R.id.box3,R.id.box4,R.id.box5}; for(int i = 0; i<5; i++){ imageButtons[i] = (ImageButton) findViewById(imageIds[i]); imageButtons[i].setBackgroundResource(R.drawable.blank); } what i would like to have it do is scale the width to fit neatly side-by-side at the bottom of the screen (which it does now ok), but have the height automatically scale to match the width as well. is this possible? i don't want to use setImageSource because then it puts a border around the imagebutton.

  • The emulator isn't showing the XML contents

    - by Roni Copul
    I have been reading Google's android tutorial (link added in the first comment) and I got a problem... In the tutorial they explain the XML elements (EditText and Button) and in the end they say how to tun the program to see the button + the text field. The problem is, that the emulator doesn't show them.. just a black screen. I even tried adding this line to the onCreate function - System.out.println("Hello World!"); but still the emulator is showing only black screen.. Here's the .java main file - http://pastebin.com/G5J9YjNe And the XML files (I mentioned what code is what file) - http://pastebin.com/VnRwAfMW What should I do? Thanks a lot for everyone who will help!

But in all the Apples apps like the Contacts App when you edit a piece of information like an Email it buts both of its rows in the middle between the Nav Bar and the Keyboard not at the top of the screen. How do I achieve this effect? Many Thanks

  • Android image scaling to support multiple resolutions

    - by tyuo9980
    I've coded my game for 320x480 and I figure that the easiest way to support multiple resolutions is to scale the end image. What are your thoughts on this? Would it be cpu efficient to do it this way? I have all my images placed in the mdpi folder, I'll have it drawn unscaled on the screen onto a buffer, then scale it to fit the screen. all the user inputs will be scaled as well. I have these 2 questions: -How do you draw a bitmap without android automatically scaling it -How do you scale a bitmap?

  • How to get the width of the whole text of the widget in WPF?

    - by macias
    Remarks Before I ask, let me focus on words: the length of "i" is 1 the length of "w" is 1 the render width of "w" is greater than "i" (except for monospace font) -- I am interested in this and from now on, I would simply write "width" The problem (small picture) Let's say I have incredible long text set for TextBlock widget which width is 100. And the text does not fit (the text is clipped -- i.e. only small portion of text is visible). The question is -- what is the width of the entire text (visible + not visible parts)? The background (big picture) I have a window width DataGrid (WPF standard) as main widget which contains text. I try to resize window and DataGrid in such way, that all texts will be visible without need of resizing and/or scrolling. I focus on width. The size of the window vs. size of the screen is not an issue, the text is so short that it would fit even on netbook screen.

  • Java long task - Did it stop writing to file?

    - by rockit
    I am writing a lot of data to a file, and while keeping my eye on the file it eventually stopped growing in size. Essentially my task is getting information from a database, and printing out all non-unique values in column A. Since there are many rows to the database table, and the database table is across my network, this is taking days to complete. Thus I'm concerned that since the file isn't growing, that it isn't actually writing to the file anymore. Which is odd, I have no "catch"'s in my code, so if there was a problem writing to file, wouldn't it have thrown an error?! Should I let the task complete (estimate 2-3 days from today), or is there something else that I don't know going on here making my application not write to the file?! my algorithm goes something like this Declare file Create new file Open file for writing get database connection get resultset from database for each row in the resultset - write column "A" to file - if row# % 100000 then write to screen "completed " + row# + " rows" when no more rows exist close file write to screen - "completed"

  • WPF Manipulation and Touch events not firing, but mouse events do?

    - by Smetad Anarkist
    I have a Samsung LD220Z multi touch monitor, and when I'm experimenting with some WPF and touch features the touch events arent firing. The mouse down event seems to be firing however. Does this mean that I have to take into account that not all touch screen behave the same, and how do I get the touch inputs on my screen? I've tried the Windows 7 Touch pack that microsoft released. And the multi touch features seems to work there. Any suggestion on how to proceed with this?

  • Socket left in TIME_WAIT after file transfer via netcat

    - by com
    Using Copying by NetCat I am trying to copy files throught network by NetCat. From console it work pretty well. First I run listening netcat on the destination machine and after I run sending on source machine. The problem is it's doen't work from script from the source machine: ssh -f user@$desthost 'nc -l 1234 | tar xvf - /dev/null &' #listening on destination host tar cv /tmp/file | nc $desthost 1234 #sending to destination host I saw that after running port 1234 is still was open and status of the socket was TIME_WAIT. If you know what's the problem, please, help me out. And by the way, after copying how can I validate that the content is identical? Thanks! Addendum: I found one very strange thing, the same implementation with screen on destination work works, but not stable, sometimes it doesn't copy a file. ssh user@$desthost screen -dm -S test 'nc -l 1234 | tar xvf - ' #listening on destination host Maybe there is an issue with timeout?

  • Determining if a coordinate is on a line

    - by TGCBraun
    I´m coding a little app that allows the user to draw multiple shapes and then remove or resize them. It´s working perfectly on rectangles and ovals, but I´m having issues with lines. Here´s a method that I wrote to find if the clicked spot on the screen is part of a specific line: public boolean containsLocation(int x, int y) { int m = (getY2() - getY()) / (getX2() - getX()); int b = getY() - (m * getX()); if (y == (m * x) + b) { return true; } return false; I´m using the famous y = mx + b formula and replacing y and x to find if the clicked spot is part of the line. The problem is when I click on the screen to remove the line, it only works if I click on the very fist coordinate (x,y) where the line starts. Nothing happens when I click anywhere else along the line. Can anyone shed a light on what I´m doing wrong? Thanks a lot.

  • in jqgrid, how can i have the editform disappear after submit

    - by leora
    right now, when i click submit it sends a message to the server and updates the databased and refreshes the screen but it keeps the edit form popup on the screen. Is there anyway to have it disappear once the submit is complete. its kind of annoying because its a little unclear that you are done because the form just sits there (even through the grid has refreshed) i have closeAfterEdit and closeAfterAdd set to true but it doesn't seem to do anything. jQuery("#grid").navGrid("#pager", { }, { height: 380, width: 500, reloadAfterSubmit: true, closeAfterEdit: true, url: siteRoot + controller + "/Update" }, { height: 380, width: 500, reloadAfterSubmit: true, closeAfterAdd: true, url: siteRoot + controller + "/Add" }, { reloadAfterSubmit: true, url: siteRoot + controller + "/Delete" }, { multipleSearch: true }
