Summary0015450: Lazarus should save window positions and sizes per resolution
DescriptionWhen I use Lazarus on my UMPC and I change the resolution by accident (wrong button) or on purpose (external monitor), the positions of Lazarus' windows are lost, when I reset the original resolution.

It would be nice if Lazarus saves the positions and sizes of its windows per resolution and reloads these settings on a resolution change.
Additional InformationI don't know about X or Carbon/Cocoa, but Windows notifies all processes with WM_DISPLAYCHANGE about a change in resolution and depth.

The attached screenshots show a sequence 1024x600 -> 800x480 -> 1024x600. The source editor window is moved to the left after the first resolution change and stays there after the second one.

Problem is similar, when a window is resized in the smaller resolution (to fit the screen), but not resized to "fill" the larger one.

Another case is a maximized window (Lazarus' main bar): the window is resized to fit the lower resolution and not restored to full size (but still in maxmized state!) once the resolution is increased again. Maybe the last problem is worth an extra issue ^^

Sounds nice… When this gets implemented, the following would be appreaciable:
when resolution changes:
  look for profile for this resolution
    if one is found, apply that profile (even save the visibility state of windows in these profiles?)
    if none is found, use the current and scale window positions and sizes according to the factors you get when you divide the old resolution by the new one. Exclude the main bar window from this, since it does not make any sense to scale this vertically (but horizontally would be nice, of course).

just a few cents ;)
