Hi Everyone,
Using Qt 4.3.1.
I am trying to reproduce the (Delphi) toolbar shown in ToolbarOrig. I have added two labels to the toolbar. When I change the text of one label, the toolbar doesn't resize.
How can I force the toolbar to recalc the positions of the actions/widgets?
Updating the text using action->setText didn't work at all. Updating the text using label->setText shows the start of the text. toolbar->updateGeometry isn't doing anything. label->adjustSize shows all of the text, on top of the next/prev buttons.
The doco for QAction add/insertWidget isn't very clear. Eg, it doesn't say who the owner of the widget should be.
Many tahnks in advance.
Tony.
Here is the code so far:
class TRisingMain : public QMainWindow
{
Q_OBJECT
public:
TRisingMain(TRisingApp *app_);
private slots:
void updateDrillToolbar();
private:
Ui::RisingMain ui;
QAction *actionSyllabus;
QLabel *labelSyllabus;
}
TRisingMain::TRisingMain(TRisingApp *app_)
: QMainWindow()
{
QLabel *label = NULL;
ui.setupUi(this);
label = new QLabel( tr("Syllabus:"), ui.toolBarTopics );
ui.toolBarTopics->insertWidget( ui.actionPreviousLevel, label );
labelSyllabus = new QLabel( ui.toolBarTopics );
actionSyllabus = ui.toolBarTopics->insertWidget( ui.actionPreviousLevel, labelSyllabus );
}
void TRisingMain::updateDrillToolbar()
{
labelSyllabus->setText( drill->syllabus->syllabus_name );
ui.toolBarTopics->updateGeometry();
}
// End of code

Thanks for that - updateGeometry did the trick. I am suprised that
adjustSize didn't do that itself!
geometryChanged doesn't compile for a QLabel. Would that be used in designer
plug-ins?
