How to pass parameters to a .ui file in Qt?

[TheIndependentAquarius]

For: http://doc.qt.nokia.com/4.7-snapshot...ml#setItemText
I wrote:

<widget class="QComboBox" name = "button55">
    <property name="ItemText">
        <number>0</number>
        <string>fontCombosBox</string>
    </property>
</widget>

<widget class="QComboBox" name = "button55">
    <property name="ItemText">
        <number>0</number>
        <string>fontCombosBox</string>
    </property>
</widget>

To copy to clipboard, switch view to plain text mode 

This results in:

ui_showmap.h:73:109: error: no matching function for call to ‘QComboBox::setItemText(QString)’
../../../../qtsdk-2010.05/qt/include/QtGui/qcombobox.h:206:10: note: candidate is: void QComboBox::setItemText(int, const QString&)

I checked: http://www.kde.gr.jp/~ichi/qt/design...l-15.html#1-19

Tried changing string to cstring. That didn't help either.

What's the way out?

P.S. Complier is g++ on openSUSE 11.3 with Qt 4.7

QComboBox::setItemTex takes 2 parameters, you're passing only one. The compilers complains on such invocation.

I *did* pass two.
First number, second string.

Now, I saw this: http://doc.qt.nokia.com/4.7-snapshot...dialog-ui.html

so the correct way is:

<widget class="QComboBox" name="zoomLevel" >
          <item>
                    <property name="text" >
		              <string>5</string>
		    </property>
  	  </item>
</widget>

<widget class="QComboBox" name="zoomLevel" >
          <item>
                    <property name="text" >
		              <string>5</string>
		    </property>
  	  </item>
</widget>

Question: Besides, qt functions also have parameter types as "QVariant". If I have to use those parameters what's the way out? Is there any proper documentation on .ui files?

[spirit]

Qt Designer has convenient QComboBox items editor. Why don't you use it instead of manually editing xml (ui) file?

[TheIndependentAquarius]

I don't have it installed currently, that's why asked.

I'm sure you do. Check your QTDIR/bin folder. Or if you are using QtCreator there is the "Designer" tab in main window.

[TheIndependentAquarius]

That's quite helpful. I opened the QtCreator and saw the designer tab. Indeed the .ui gets generated automatically. That's the reason perhaps that there is no proper documentation for it.

There is documentation but it's not a part of Qt's docs. It's part of the QtCreator's docs. See Developing Widget Based Applications.
