Highlight an item in QCombobox by text color

[emp1953]

Have found the solution after writing bug report to nokia. Solution: connect signal currentIndexChanged(int) of the combobox (signal activated(QModelIndex) from QTreeView was not emitted for some reason) and process it in a slot to change parent items color and font when selected:

connect(myCombobox, SIGNAL(currentIndexChanged(int)), myCombobox, SLOT(setupComboboxFont()));

connect(myCombobox, SIGNAL(currentIndexChanged(int)), myCombobox, SLOT(setupComboboxFont()));

To copy to clipboard, switch view to plain text mode 

in slot we write:

void KComboboxBox::setupComboboxFont()
{
	QFont comboboxFont = font();
	QPalette comboboxPalette = palette();
	QModelIndex index = ((QTreeView *)view())->currentIndex();
	if(!index.parent().isValid()) // parent index
	{
		comboboxFont.setBold(true);	
		comboboxPalette.setColor(QPalette::Text, Qt::blue);
		comboboxPalette.setColor(QPalette::WindowText, Qt::blue);
	}
	else
	{
		comboboxFont.setBold(false);	
		if(parentWidget() != 0)
			comboboxPalette = parentWidget()->palette();
	}
	setFont(comboboxFont);
	setPalette(comboboxPalette);
}

void KComboboxBox::setupComboboxFont()
{
	QFont comboboxFont = font();
	QPalette comboboxPalette = palette();
	QModelIndex index = ((QTreeView *)view())->currentIndex();
	if(!index.parent().isValid()) // parent index
	{
		comboboxFont.setBold(true);	
		comboboxPalette.setColor(QPalette::Text, Qt::blue);
		comboboxPalette.setColor(QPalette::WindowText, Qt::blue);
	}
	else
	{
		comboboxFont.setBold(false);	
		if(parentWidget() != 0)
			comboboxPalette = parentWidget()->palette();
	}
	setFont(comboboxFont);
	setPalette(comboboxPalette);
}

To copy to clipboard, switch view to plain text mode 

That is all!!! Workable!

In Line 5, I get a compiler error for view() are you casting view() to a (QTreeView *)

error: 'view' was not declared in this scope
QModelIndex index = ((QTreeView *)view())->currentIndex();

Well, view() is a valid method in a QComboBox subclass, so maybe you are not inside such a class?
