[bug] Fullscreen doesn't work with 2 displays when one of them has Windows scale setup

[joao-bolsson]

Hi! I'm studying your framework and I'm using two displays in Windows platform. I set the scale of one display up to 125% and left the other one normal (100%). When I externalize a dock to another display (125) and keep the root on the other (100), the fullscreen doesn't fill all the available space.

The following code gives me the right scale, in this case: 1.25.

GraphicsDevice device;
double scale =device.getDisplayMode().getWidth() / device.getDefaultConfiguration().getBounds()

I already tried to just multiply the bounds (w and h) by thatscale, but it didn't work, seems to me that have another code working on that as well, but I'm not pretty sure about it.

I'm working on the class DefaultScreenDockFullscreenStrategy. If you have some idea of what could be, please give a return and I can send the fix.

lol, I did never think of such a configuration.

You are probably stopped by the BoundaryRestriction, which is there to ensure that a window cannot be dragged outside of a screen.

Try disabling the restriction with:
CControl.putProperty(ScreenDockStation.BOUNDARY_RESTRICTION, BoundaryRestriction.FREE)

Thanks for answering, but it didn't work :( haha
The problem with the dimension only happens when the panels are in different displays. If both are in the same display (with scale or not) the fullscreen works fine.

I'll give some more shots in this issue and try to solve, any help is welcome :)

[update]:
case 1: both panels (root and externalized dock) in the same display with 125% of scale
case 2: externalized dock in the display with 125% and root in another display with 100%

from DefaultScreenDockFullscreenStrategy.findBestFullscreenBounds is returned the same Rectangle for both cases, but with case 1 the externalized dock fills all the available space, but in the case 2 doesn't. Looks like the framework is getting some configuration from where the root panel is.
