Description
When running a sketch that uses the P2D or P3D renderer. The WM_CLASS window variable is not set. This makes it difficult (impossible?) to set window rules for the resulting window. (For example, making it so a tiling window manager makes the window float by default, instead of resizing it.)
Expected Behavior
WM_CLASS should be set to "Processing", "processing-sketch"
or similar. For reference, the main processing app has a WM_CLASS of "Processing", "Processing"
and a sketch with the default renderer has a WM_CLASS of "processing-core-PApplet", "processing-core-PApplet"
.
Current Behavior
The WM_CLASS variable is not set. (I don't mean empty, it just doesn't exist)
Steps to Reproduce
- Run a sketch that uses P2D or P3D as a renderer. Example code:
size(128, 128, P2D);
- Inspect the window class with
xprop
(or another similar tool). To usexprop
, simply run it on a terminal and click on the window. You can also pipe it intogrep
to filter out the other variables:xprop | grep WM_CLASS
