| Summary | 0019886: Form with only width constraint changes height to zero after minimize/restore | ||||
| Description | If a form has Constraint.MinWidth set but MinHeight is 0 (so, no constraint) then after minimize/restore width is set to MinWidth and height is set to 0. This stems from the fact that in LCLWin32 minimized form has Width,Height=0. Without constraints the size is somehow remembered upon restore but with MinWidth>0 on minimize the size is set to Width=MinWidth, Height=0. And upon restore those values are used to resize the form thus only the caption bar is visible. This obviously works in other ways too (MinHeight > 0, MinWidth = 0). I checked with Linux LCLGTK2, LCLQT and it works fine. | ||||
| Steps To Reproduce | 1. Run attached application. 2. Minimize Test Form. 3. Restore Test Form. | ||||
| Tags | No tags attached. | ||||
| Fixed in Revision | r33145 | ||||

In branch fixes_0_9_30 rev. 31839 the bug does not exist. With trunk the bug appears since revision r29756: http://svn.freepascal.org/cgi-bin/viewvc.cgi?view=rev&root=lazarus&revision=29756 |
|
|
I can't reproduce this with the latest Lazarus trunk [edit: on Windows 7]. Maybe it is a Windows version dependent issue. |
|
|
Indeed, it doesn't happen anymore after rev. 33145, however 33145 in turn causes a regression: 0020670. |

I resolved this and set 20670 as a related issue. |
