A QWidgets' width in QToolBar
Message 1 in thread
Hi there,
This is Qt 4.3.0
I'm trying to have the QWidgets of a QToolBar all the same width.
This is how it currently works in our application, and imho it's a bit easier
on the eyes and looks 'cleaner'.
Well, I have this piece of code run in void showEvent(QShowEvent *e) of a
QDialog-derived class after I added all the actions:
QList<QAction*> a = toolbar.actions();
int max_widget_size = 0;
QList<QWidget*> widgets;
for(QList<QAction*>::iterator i = a.begin(); i != a.end(); ++i)
{
QWidget *w = toolbar.widgetForAction(*i);
if( w->width() > max_widget_size )
max_widget_size = w->width();
widgets.push_back(w);
}
for(QList<QWidget*>::iterator i = widgets.begin(); i !=
widgets.end(); ++i)
(*i)->setMinimumWidth(max_widget_size);
This seems to work -- every QWidget has the same width. But the width
is far wider than the widest QWidget normally would be. I've tried executing
exactly that code in a on_button_clicked() so it is executed after the dialog
has been shown completely, and it works exactly like I want it.
Now here's the issue: It seems the QWidgets in the QToolBar will be resized
somewhere after showEvent() runs. When might that be and what chances do
I have to run code to the right time?

Daniel Albuschat
