| Summary | 0019069: Wrong modal form behavior in windows | ||||
| Description | After returning to application with activated modal form this form must be brought to front. In case of LCL ShowModal() it is not so. The example of this is Lazarus IDE. Steps to reproduce: 1. Start Lazarus and create new Application project 2. Go to "Options of project" dialog (menu Project|Project options or Shift+Ctrl+F11) - img01.png 3. Now you need another application to activate (e.g. FireFox) 4. Try to activate Lazarus again by clicking on its main form - img02.png Unfortunately, Lazaru IDE will not activated, but when we try to activate it by clicking on it in the taskbar, it will. | ||||

qt works fine, and I don't like your patch. It could be win32 only problem, and adding your patch can easy produce a mess with others. |
|
|
In my ide I set "Application.MainFormOnTaskbar := True; ", the problem did not appear. |
|
|
Qt must be tested separately under windows and under linux. Zeljan, indeed it is not a patch, it is only "direction". yang, it really fixes the problem, but I'm not sure, that it can be applied for Lazarus main project. |
|
|
Anton, your fix doesn't work even on Windows 7. It prevents any other application gaining focus. How could it work for you? |
|
|
As I already mentioned, this patch isn't good, roots of problem are somewhere else inside win32 ws code, and I think it can be fixed there when application activate occurs, that it should bring to top modal windows. |

I think that Paul fixed this recently...please test with 0.9.31 >= 36116 |
|
|
Can you test with recent trunk ? |
|

Lazarus 0.9.31 r36160M FPC 2.6.0 i386-win32-win32/win64 Microsoft Windows [Version 6.1.7601] (win7 HP x64 with disabled themes) Issue still alive. |
|
|
Please test and close if ok. |
|
|
Now it works, great! Thank you! |
