QToolBox Colors

[rooney]

Hi,

I am trying to format a QToolBox.
Can anyone tell me a way to set a different background colors to the different tabs (headers) of a QToolBox?

Your help greatly appreciated!

Adapt the idea from this:

#include <QtGui>
 
static void setToolBoxButtonColor(QToolBox* toolBox, int index, QColor color)
{
	int i = 0;
	foreach (QAbstractButton* button, toolBox->findChildren<QAbstractButton*>())
	{
		// make sure only toolbox button palettes are modified
		if (button->metaObject()->className() == QString("QToolBoxButton"))
		{
			if (i == index)
			{
				// found correct button
				QPalette p = button->palette();
				p.setColor(QPalette::Button, color);
				button->setPalette(p);
				break;
			}
			i++;
		}
	}
}
 
int main(int argc, char *argv[])
{
	QApplication a(argc, argv);
 
	QToolBox* toolBox = new QToolBox;
 
	toolBox->addItem(new QLineEdit("HAHA"), "LineEdit");
	toolBox->addItem(new QTextEdit("HOHO"), "TextEdit");
	toolBox->addItem(new QLabel("MUAHAHA"), "Label");
 
	setToolBoxButtonColor(toolBox, 0, Qt::red);
	setToolBoxButtonColor(toolBox, 1, Qt::green);
	setToolBoxButtonColor(toolBox, 2, Qt::blue);
 
	toolBox->show();
 
	a.connect(&a, SIGNAL(lastWindowClosed()), &a, SLOT(quit()));
	return a.exec();
}

#include <QtGui>

static void setToolBoxButtonColor(QToolBox* toolBox, int index, QColor color)
{
	int i = 0;
	foreach (QAbstractButton* button, toolBox->findChildren<QAbstractButton*>())
	{
		// make sure only toolbox button palettes are modified
		if (button->metaObject()->className() == QString("QToolBoxButton"))
		{
			if (i == index)
			{
				// found correct button
				QPalette p = button->palette();
				p.setColor(QPalette::Button, color);
				button->setPalette(p);
				break;
			}
			i++;
		}
	}
}

int main(int argc, char *argv[])
{
	QApplication a(argc, argv);

	QToolBox* toolBox = new QToolBox;

	toolBox->addItem(new QLineEdit("HAHA"), "LineEdit");
	toolBox->addItem(new QTextEdit("HOHO"), "TextEdit");
	toolBox->addItem(new QLabel("MUAHAHA"), "Label");

	setToolBoxButtonColor(toolBox, 0, Qt::red);
	setToolBoxButtonColor(toolBox, 1, Qt::green);
	setToolBoxButtonColor(toolBox, 2, Qt::blue);

	toolBox->show();

	a.connect(&a, SIGNAL(lastWindowClosed()), &a, SLOT(quit()));
	return a.exec();
}

Edit: This will naturally work only if items toolbox items are added by QToolBox::addItem(). Using QToolBox::insertItem() in arbitrary order will also make toolbutton's children laid in same order and the color is set for a wrong button. QObject docs promise that:

The first child added is the first object in the list and the last child added is the last object in the list, i.e. new children are appended at the end.

no need to write code use ui file with style sheet like below code:
#toolBox my control name
-----------------------------------------------------------------------------------
#toolBox::tab:selected { font: bold; color: #4FA600;height: 26px;} /* selected tab */
#toolBox::tab:!selected { font: bold; color: rgb(85,85,84);height: 26px;} /* non-selected tab */
#toolBox{
border: 0px transparent;
}

#toolBox::tab:QToolButton{
border: 1px transparent;
border-top-left-radius: 6px;
border-top-right-radius: 6px;
background-color: rgb(234, 234, 234); /* Button background color no need to write long code */
}
