Tlistbox is moving when resizing

[Wanagen]

Hi.
I've got some little problems at design time using Linux Mandriva 2007.0

With default project and just one tlistbox.

Lazarus 0.9.22 :
when i try to resize the tlistbox with the mouse, the top and left position change +1 each at each step. And when i resize this tlistbox, if i move the mouse too fast, the tlistbox border is no longer following the mouse cursor.

Lazarus 0.9.20 :
same problem.

Lazarus 0.9.18:
Works perfectly, not changing the top and left position and the tlistbox border always follow the mouse cursor.

All three Lazarus were rebuilt with Free Pascal Compiler version 2.0.4 [2006/08/20] for i386 and gtk2 widgettype.

[Marc]

Ehm, did you report this problem for 0.9.20 ?

[Wanagen]

I've not used Lazarus 0.9.20 for linux before. I've downloaded it just to verify if there was the same problem as in 0.9.22.

as i typed that i done another test.

The problem is only with gtk2. With gtk1 all work correctly but that's not a solution.
I can't try with qt or gnome because i haven't got the appropriate libraries.

well continuing tests ...(Lazarus 0.9.22 + gtk2)

Same problem with TListBox, TColorListBox and TFileListBox.
No problem with TCheckListBox.( no font control )

In the editor when i just click it's ok but if i try to select some words the end of the selection go 1 or 2 line down under the mouse cursor. (depending of the font i use) I try all the fonts and the same thing go wrong.

[Wanagen]

Well, i've got now the good libraries to try in qt4.
libqt4intf.so compile correctly and i had copied it in /usr/lib
Lazarus compile (clean all) correctly but when i launch it it give me this before quit :

Then it's not a solution.

Bad luck for me.

Before this point there is no error.

Any suggest ?

[Vincent Snijders]

the gnome error has been fixed.

For QT, only compile the LCL for qt, but not Lazarus, because the QT widget set interface is not ready for use by such a complex application as Lazarus.

[Vincent Snijders]

Sorry, I confused that error for another error. Please submit a bug report.

[Vincent Snijders]

On a second thought, you don't need to create a bug report for the compilation failure with gnome.

We will remove the gnome interface shortly from Lazarus.

The gnome interface was only a simple extension of the gtk 1 interface with some dialogs. Those dialogs are now part of gtk2. The gnome interface was not maintained anymore and is broken for more than six months without anybody noticing or complaining (you are the first).

[Wanagen]

Thanks.

So i have to rebuild Lazarus 0.9.23 with gtk1 or Lazarus 0.9.18 with gtk2 to draw listbox and to select text correctly.

[Marc]

Yes, and report it as bug (if it is not already reported)

[Wanagen]

OK selecting text work correctly with Lazarus 0.9.23-20070412

I've reported for tlistbox problem.

[Wanagen]

Well,
with last daily snapshot (20070628) resizing tlistbox work correctly.

The 3 bugs i reported are still in "acknowledged" mode.
Must i write a note to modify the status to "resolved" ?

[Marc]

iirc, you can close yuor own bugs (if not, leave a note)
