[Qt-interest] How to select and test Qt-internal plugins?

[Rick Stockton]

Hi, everyone ;)

I'm in the process of writing an Update to support 31 mouse buttons into 
Qt 5.0.0, and I need a way to specify which plugin actually gets used. 
(These are Qt plugins, not my own.) Even though my primary targets are 
X11-XCB and Wayland, Qt itself still contains a large number of "legacy" 
plugin interfaces.

Is there a way to specify which one to use, without rebuilding Qt from 
hacked-up configuration files for each plugin?

It would be even better if I could iterate through ALL runnable plugins 
on my platform.
