[Ltilib-devel] Catch mouse button pressed events in viewer

[Per R. <pe...@kt...>]

How do I catch mouse button pressed events in viewer? I tried to
reimplement viewer::mainWindow::mouseButtonHandler in a mainWindow child
class, and viewer::ensureWindow to create objects of the new class, in a
new viewer child class, but I failed since ensureWindow isn't virtual.

My only solution right now is to copy and modify viewer to notify my
program of key pressed events, or to replace the show and ensureWindow
functions, but these solutions are very ugly.
