adding icons from resources to buttons without Qt3Support

**skyphyr** · 5th December 2006, 14:36

Hi All,

I've got a resource file which I've used to add icons to buttons in designer.

The problem I've hit is that the code it generates uses qPixmapFromMimeSource - which I can get to work using Qt3Support, but I'd rather have it generate Qt4 style code.

Anyone know how I can get it to do this? Or what I should be using if I put the changes into the constructor of my class which inherits this ui file?

Cheers,

Alan.

In Qt4 you should create a qrc file and use a proper URI to reach the resource from your code. What buttons are we talking about here anyway? Qt3 ones?

Hi wysota,

Sorry for the delay - I complete forgot I posted this for a while with other issues popping up.

The project has only been done in Qt4 and the button type is QToolButton.

I have used a .qrc file - here's an example section from the .ui file

Qt Code:

Switch view

<widget class="QToolButton" name="taskResume" >
            <property name="sizePolicy" >
             <sizepolicy>
              <hsizetype>5</hsizetype>
              <vsizetype>5</vsizetype>
              <horstretch>0</horstretch>
              <verstretch>0</verstretch>
             </sizepolicy>
            </property>
            <property name="toolTip" >
             <string>Resume Task</string>
            </property>
            <property name="text" >
             <string>></string>
            </property>
            <property name="icon" >
             <iconset resource="../splishgraphics/splishgraphics.qrc" >:/icons/splish_play.png</iconset>
            </property>
            <property name="iconSize" >
             <size>
              <width>32</width>
              <height>32</height>
             </size>
            </property>
           </widget>

<widget class="QToolButton" name="taskResume" >
            <property name="sizePolicy" >
             <sizepolicy>
              <hsizetype>5</hsizetype>
              <vsizetype>5</vsizetype>
              <horstretch>0</horstretch>
              <verstretch>0</verstretch>
             </sizepolicy>
            </property>
            <property name="toolTip" >
             <string>Resume Task</string>
            </property>
            <property name="text" >
             <string>></string>
            </property>
            <property name="icon" >
             <iconset resource="../splishgraphics/splishgraphics.qrc" >:/icons/splish_play.png</iconset>
            </property>
            <property name="iconSize" >
             <size>
              <width>32</width>
              <height>32</height>
             </size>
            </property>
           </widget>

To copy to clipboard, switch view to plain text mode

Thanks for the help.

So what is the problem?

**skyphyr** · 24th December 2006, 12:24

The problem is that it creates code which requires qt3support, not code which is purely qt4.

Cheers,

Alan.

**wysota** · 24th December 2006, 13:16

What exact symbols does it need from Qt3support?

**skyphyr** · 30th December 2006, 16:11

Hi wysota,

It needs qPixmapFromMimeSource from q3mimefactory.h

Cheers,

Alan.

Can you post a small compilable example experiencing such a behaviour? Are you porting from Qt3? In the snippet you posted everything seems to be fine, the problem has to be elsewhere...

**Glitch** · 8th January 2007, 21:51

I have run into this when porting Qt3 forms to Qt4. You should just delete the pixmapFunction (or something to that effect) tag and its contents from the .ui file by hand. Worked for me. Newly created forms should not have this problem.

Hi,

Sorry again for the delay. This has definitely fixed it for me :-) I've only even worked in Qt4 for this project - perhaps I accidentally opened the ui in kdevelop's embedded designer?

Thanks very much for the help with this one.

Cheers,

Alan.
