Programming :: Can't Get Xlib Window To Display / What To Do?
Mar 12, 2009I am having trouble writing an Xlib application that displays a window. The most frustrating thing is that I've written applications like this before, and never had any problems. For some reason I cannot get this program to work properly. I'm running KDE and when I launch the program, a "button" for the application will appear on the application panel, however, no window will display. It is possible to right click on the panel button and select the Close item which will successfully close the window.
The following is source code that when built will exhibit the behaviour described above code...
Programming :: QSplashScreen And QPainter - Draw Shapes And Gradients

How would I best achieve this:
- Draw some shapes and gradients with QPainter/QPen etc
- Create a splash screen out of it
- Display SplashScreen.
I cannot find anything that doesn't involve

I am comfortable making splash screens out of images, but now I want to try drawing one myself.

View 6 Replies View RelatedProgramming :: Xlib - C Programming - Get Value From Pixel
Dec 11, 2009I'm making a game with the xlib library. What I want to do is to know if the character is standing on a trap or something else.
So far I've solved that using the coordinates but when I draw circles or stuff not shaped like a rectangle it gets to hard to make the game exact.
So what I'm asking for is if there is some kind of function in the xlib that tells you which color a pixel has. Because then it'd be much easier.
I've searched but I haven't been able to find anything good. I found XGetPixel() but that appears to work only with images, maybe I can make my window to be an "image"?
Programming :: Use Colors In Xlib Programming ?
Apr 27, 2010I'm trying to understand how to use colors in Xlib programming. What I think I understand so far is that modern displays use 24 or 32-bit TrueColor. And TrueColor uses three colormaps, one for each primary color, and a single pixel value is composed of three indices.
Now the part i'm confused about is how to get my programs to use a 32-bit TrueColor visual. I thought I could inheret the visual from the root window to get color but it seems no matter what pixel value I use it's either black or white.
I guess my question is, how can I setup my programs so that I can specify a pixel value that is a combination of RGB values to get the color I want?
I come from windows where I simply used RGB(r,g,b) macro to specify colors and never had to worry about depth and colormaps and visuals, so I'm a bit overwhelmed by all of these concepts.
Programming :: Xlib Documentation With GUI Programming?
Dec 14, 2008I want to do some experimentation with GUI programming. What mostly interests me is how the toolkits actually work (what are the drawing mechanisms, how it communicates with X, etc.) and how the window managers work. I know it's quite a lot but I don't plan on developing the next best DE/Toolkit/Window Manager, just to play with API, mostly to learn. It seems that there is a shortage of documentation on this topics, I'm trying to find anything for 2 days now with no result.

Please don't tell me to download binaries, I cant do that, it wont work. Unless you have armeb binaries for me.

View 4 Replies View RelatedProgramming :: WM-hints And Moving Window?
Sep 7, 2010I have a toplevel window that I want to place depending on another toplevel window. I use gtk_window_move(widget, x, y); At startup this function is called several times and y is changed ones from 412 to 413 and x is always 0(checked with gdb in netbeans). The window gets placed at x=10 and y=400 or so. If I do not use variables but pure ints for x and y it gets placed correctly even if its the same values. I suspect that my window manager notice this change of y and place the widget for me. Is this correct and how do I tell the WM not to do so?
This change of y is due to window size is just a local size and not the correct one as in X. Can i force uppdates from X to the local cache?
