bug in designer's editor

Qt 3.3.3 has just been released and i found a bug in the designer's editor: the lines are not tabbed correcly. when selecting text and then hitting the tab key, the lines should be tabbed like:

Source code

 
1
2
3
4

   if ( ... )
        my code
    else
        my other code;


instead i get:

Source code

 
1
2
3
4

    if ( ... )
 my code;
    else
 my other code;


even hitting tab at the begining of line 2 does not push it!

This kind of bug should be in a final release especially when they are not present in one of the previous snapshots of that release!!

Have you tried setting the tab behaviour trough the preferences??
I doubt the designer has such a bug.

yes sure. same parametres.

actually it happens with old files written with qt's editor of a previous sanpshot of qt3.3.
I just put the cursor at the begining of the line, hit tab and the text comes back at the beginin of the line!

bug in designer's editor

I had the same experience when upgrading from v3.3.2 to v3.3.3 on my Gentoo system. I solved it by changing the editor's font to a non-proportional one in the Preferences.

BTW: when you enter a partial variable name and hit the Tab key the Designer's editor pops up a listbox for name completion. Handy ! But it probably gets confused about this dual meaning of the Tab key.

RE: bug in designer's editor

There is a (very old) bug in QTextParagraph class which has been fired up in 3.3.3.
You can patch the widget (very simply) using the patch available at:

or freebsd.ports.bugs

The bug itself lies in the paint method in:

Someone should bother to incorporate this patch into the official release.
