◆ switchCanvasOnly

void KisViewManager::switchCanvasOnly ( bool toggled )

slot

Capture the initial canvas position.

Going into a fullscreen mode is a multistage process that includes making the window fullscreen. It means that it is not easy to catch a moment, when the new state is "fully established". First, it hides the dockers, then it hides the menu, then it makes the window fullscreen (hiding titlebar and "start" menu). And these actions happen in the course of dozens of milliseconds.

And since we cannot catch the moment when the new state is "fully established" we use a heuristic (read "a hack") that just pre-scrolls the canves into an expected offset. The prescroll offset is saved globally, so that when exiting the fullscreen mode we would know how big the new offset should (since we cannot get the real value of it).

Here are the list of cases when this approach fails:

1) When the fullscreen window migrates to a different screen, potentially with a different resolution (while being fullscreen)

2) When dockers or toolbars are visible, and the user resizes them while the window is fullscreen.

In both the cases the saved offset in d->canvasOnlyOffsetCompensation becomes invalid and the window jumps in an offset direction on exiting the fullscreen mode.

Restore state uses the current layout state of the window, but removal of the menu will be backed into this state after receiving of some events in the event queue. Hence we cannot apply the application of the saved state directly. We need to postpone that via the events queue.
