| Summary | 0036127: [Patch] TForm's bounds and restored bounds are inconsistent | ||||
| Description | The attached patch tries to fix the following issues: When form is designed with WindowState=wsMaximized: 1. Restored dimension is wrong (related to 0027894, 0022771, 0027375) 2. Width/Height in OnShow() and OnActivate() events are wrong (related to 0021119) Under Delphi 3: - OnCreate(): design time restored width/height - OnShow() and OnActivate(): maximized width/height When form's WindowsState=not maximized 3. Restored bounds in OnResize() and OnChangeBounds() events are wrong or not updated (related to 0032631) Note: Expanded on the idea of Yuichiro Takahashi from Issue 0008576 to use Application.QueueAsyncCall() to "queue" the procedure to update the restored values, to the main event loop, thus delaying it until the form is properly moved or resized. The first calls to OnShow() and OnActivate() are also moved to this procedure so that querying Width/Height during these events will return the correct values. Tested on GTK2 and Win32. | ||||

Updated the patch (v2) with the following fixes: - because the queued procedure is shared between WMMove and WMSize events, an event is sometimes missed because duplicate calls are discarded.

Interesting! How many of the related issues this would fix? I think this should be applied and tested in trunk. |

I applied the patch in r61997 for everybody to test. Let's see if somebody finds bugs in it. |

Another one :) GTK2 only: When a form is designed so as part of it is clipped off the screen, and WindowState=wsMaximized, width and height during onShow()/onActivate() is wrong. Reason: After creation (?), the window manager automatically moves the form so that the whole form is visible. This will trigger WMMove() events, thus triggering the delayed onShow()/onActivate() even before the form is maxmimized. Solution is to wait for the first WMSize() before triggering onShow()/onActivate(). Apply patch after the v2 patch. |
