In fact, when I tried (after running "make x01c" and "make wxwidgets") examples/c/x01c -dev wxwidgets -locate -drvopt backend=0 examples/c/x01c -dev wxwidgets -locate -drvopt backend=1 examples/c/x01c -dev wxwidgets -locate -drvopt backend=2 that device it turns out that the fundamental interactivity features are available (although the agg backend does not identify the key strokes for some reason, and the other backends that identify the keystrokes fail to identify which mouse button was pushed). Of course, this result is on Linux with X serving as the fundamental graphical software library supporting wxwidgets, and I am not sure whether you will get the same result on the Windows version of wxwidgets. If you can get it to mostly work like I described, it would be a help if you refined it so all three backends produced good identification results including mouse button identification and distinguishing between press and release (see below). If you ever install GTK+, then using the xcairo device on the above example produces (at least on Linux) the ideal result; _every_ keystroke and mouse button is identified both on press and release. That latter feature is important since it allows the CLI to identify drag and release events with any key where the user holds down the key and only releases it when the cursor has been moved to a new position. Other interactive devices on Linux are not that good with no release identification (all of them other than xcairo), missing identifications altogether (qtwidget), missing mouse button identifications (xwin), etc. So there is some work to do to bring them all up to the level of xcairo, and your help with the part of that work needed for wxwidgets would be much appreciated if Windows already gives you access to the partial interactivity that shows up on Linux for the 3 different versions of that device.
