QTreeWidget + ScrollBar

[raphaelf]

Hi everybody!

QT:4.1.1
Compiler: MINGW
OS: WINXP PRO

I am using a Tree Widget for showing some tables from a Database. The Vertical Scroll Bar is Working fine (if is necessary it appears automaticaly), but the horizontal one not.( the scrollBar never appears).

I am Working in the Designer and have for both the same Settings (default):

verticalScrollBarPolicy: Qt::ScrollBarAsNeeded
horizomtalScrollBarPolicy: Qt::Qt::ScrollBarAsNeeded
autoScroll: auto

Can somebody tell me why the horizontal Scrollbar never appears on my Tree?

As far as I can see the horizontal scrollbar only appears when you drag beyond the first column of the tree widget.
Could you try making it as small as posszible to see what happens?

Cheers

Hi Everall

Here the result:

[Everall]

there has been a bug filed in task tracker :

103904 - QTreeWidget with 1 column never shows a horizontal scrollbar

Scheduled for?
4.2.0

Description

A QTreeWidget with 1 column never shows a horizontal scrollbar. A vertical scrollbar shows up when the items total height exceeds the widgets' height, but this never happens for a horizontal scrollbar, even though the policy is set to Qt::ScrollBarAsNeeded, the resizeMode to custom and the stretching of the last column to false.

Update:
Fixing this will change behavior that other customers are relying on. Will be fixed in Qt 4.2.

Guys dont forget that free windows version has some limitation

Before I got a commercial license for Qt I was using the OpenSource version with MinGW, which worked fine against my PostgreSQL database. After I installed the commercial version I compiled against Oracle without changing the code (except for aggregate sum selects), and that worked fine also.

Aside from lacking drivers for Oracle, SQL Sever, etc... what limitations would those be?:

Its not limitation as such, but there is available some disagreeable bugs, that occasionally surface in different qt forums, and support only by free windows version

Are you talking about Qt 4 Open Source Edition or Q..3/Windows Free Edition?

I mean Qt4 open source

Do you have any examples of such bugs?
