[Qt-interest] Multiple monitors and multiple input devices

[Matthias Paul]

Dear Qt community,

I'm currently working on a new display setup: Windows 7x64 machine plugged to a usual HD display as primary display device.
Also there's a small LCD display (800x400 pixel), which is attached to secondary graphics adapter output.

I'd like to separate the two desktops which are currently init'ed as one virtual display using Qt:

1. The user must not be able to move dialogs/windows from one display the one.
Already partly fulfilled, because I prevent to move the widget from LCD to HD by setting the window size as fixed and maximize it. Still I'm able to move windows from HD to LCD. I'd be able to catch QMoveEvent and QResizeEvent of my Qt widgets and check them, whether they are spanning into second display and react. But I guess, I cannot catch events of native windows applications to prevent the same behaviour, am I right?

2. The user must not be able to operate with the mouse on LCD display (secondary).

3. The user must not be able to operate with the additional touch pad, which is attached to LCD, on HD display (primary).
This is easy by driver setting. Nevertheless, after using the touchpad and then returning to mouse input, the mouse cursor is located on touchpanel region. There seems to be no way to use both inputs at the same time, is there one?

I'm not sure: Can touchpad and mouse be distinguished programmatically, so I simply push cursor to a valid location, if they leave their areas (LCD or HD)?

Thank you for reading!
Paule
