Resize toolbar buttons?

Hello,

I have a main window with a dock witget. Inside the dock widget I have a Toolbox. Each toolbox item has a vertical toolbar to which I add actions. However it doesnt look the best. I have attached the screenshot. You can see the toolbar button is only big enough as the text. This usually makes sense for a button, and even toolbar button, since toolbars are usually horizontal. In reality the texts in the buttons will not be all the same lenght like they are in the image. This results in a rather ugly looking dockwidget, with all the buttons having varying sizes. Is there any way to make all the buttons stretch horizontally so that they fill 100% of the toolbar, all the way to the right side. I have tried a few things trying to force a layout onto toolbar, and playing with size policies; but all without sucess. This is done in Qt4, which I am stil getting familiar with. Any help is much appreciated.

RE: Resize toolbar buttons?

Did you try changing the horizontal size policy to Expanding? Do you have a layout set for the toolbox page?

void MainWindow::createToolbox()
{
	QDockWidget *dw = new QDockWidget( tr("Toolbox"), this );
	dw->setAllowedAreas( Qt::LeftDockWidgetArea | Qt::RightDockWidgetArea );
	dw->setFeatures(QDockWidget::AllDockWidgetFeatures);
	m_settingsMenu->addAction(dw->toggleViewAction());
        
	addDockWidget( Qt::LeftDockWidgetArea, dw );
    
	m_toolBox = new QToolBox( dw );
	
	dw->setWidget( m_toolBox );
	dw->setMinimumWidth( 110 );
	
	for(int groupNumber = 0; groupNumber < m_nGroups; groupNumber++)
	{
		QToolBar* tb = new QToolBar(m_toolBox);
		tb->setOrientation(Qt::Vertical);
		tb->setToolButtonStyle(Qt::ToolButtonTextBesideIcon);
		
		/*QVBoxLayout *layout = new QVBoxLayout();
		tb->setLayout(layout);
		tb->setSizePolicy(QSizePolicy::Expanding, QSizePolicy::Expanding);*/

		m_toolBox->addItem(tb, m_groupIcons.at(groupNumber), m_groupNames.at(groupNumber));

		for(int actionNumber = 0; actionNumber < m_groups[groupNumber].size(); actionNumber++)
		{
			tb->addAction(m_groups[groupNumber].at(actionNumber));
		}
	}    		

	dw->show();
}


I have tried the code in the comment. Or just setting the size policty, and no layout. I also tried using MinimumExpanding. That had to effect on the buttons. I think thhe size policy stuff acts on the toolbar, in respect to its parent. not how the widgets in the toolbar will look. Also when I set the layout, it prints:

QWidget::setLayout() : QLayout "" added to QToolBar "", which already has a layout


Not sure if this is good or bad.

Were you refering to this? Or what widget?

I can achieve the desired look if I use QPushButtons. This is the code:

void MainWindow::createToolbox3()
{
	QDockWidget *dw = new QDockWidget( tr("Toolbox"), this );
	dw->setAllowedAreas( Qt::LeftDockWidgetArea | Qt::RightDockWidgetArea );
	dw->setFeatures(QDockWidget::AllDockWidgetFeatures);
	m_settingsMenu->addAction(dw->toggleViewAction());
        
	addDockWidget( Qt::LeftDockWidgetArea, dw );
    
	m_toolBox = new QToolBox( dw );
	
	dw->setWidget( m_toolBox );
	dw->setMinimumWidth( 110 );
	
	for(int groupNumber = 0; groupNumber < m_nGroups; groupNumber++)
	{
		QFrame* frame = new QFrame(m_toolBox);
		frame->setFrameStyle(QFrame::NoFrame);
		frame->setSizePolicy(QSizePolicy::Minimum, QSizePolicy::Fixed);

		QVBoxLayout *layout = new QVBoxLayout();

		m_toolBox->addItem(frame, m_groupIcons.at(groupNumber), m_groupNames.at(groupNumber));

		for(int actionNumber = 0; actionNumber < m_groups[groupNumber].size(); actionNumber++)
		{
			QPushButton* btn = new QPushButton(m_groups[groupNumber].at(actionNumber)->icon(), m_groups[groupNumber].at(actionNumber)->text(), frame);
			btn->setToolTip(m_groups[groupNumber].at(actionNumber)->toolTip());
			btn->setStatusTip(m_groups[groupNumber].at(actionNumber)->statusTip());
			btn->addAction(m_groups[groupNumber].at(actionNumber));
			connect(btn, SIGNAL(clicked()), m_groups[groupNumber].at(actionNumber), SLOT(trigger()));
		
			layout->addWidget(btn);
		}
		frame->setLayout(layout);
		
	}    		

	dw->show();
}


However, this isn't as nice code as just having the actions. It looks a little different, than with toolbar, but it is ok. Also there is some weird little drawing artifact when I do it this way. See the attached image. It goes away after all the toolbox items have been clicked. Not the individual buttons, just the groups.

I am not really opposed to doing it this way. But if I can get the buttons to stretch in a toolbar, I'd rather use that. So if there is a way I'd like to know.

Thanks,

Latem

It's bad.

To the QFrame from your second example.

Use QToolButtons instead.

OOhh right; I forgot about, or missed the QToolButton. Ok that is better. I think actually I'll use that.

Thanks jacek,
