[Qt-interest] ***SPAM*** Re: Query related selection color in Qt

[Ramesh]

Ya I do agree with that point,

But logically if we think, the control comes to customized paint method
here, painter is a pointer, we are going to modify and passing it to the
base class.

Where else painter value gets changed?

Hi,

I want to highlight the selected item text color in listview, for this I am
painting  the text in delegate method.

My problem is, if I set the pen to painter and draw the text manually it
works, but if the system draw text it doesn’t work 

May I know the reason why it happens like this?

 

Here is the sample code of delegate where my problem is occurring.

 

In this code, I am setting the pen color to painter and passing it to base
class to draw, still painter doest draw with the color which I set.

 

const bool sel((option.state & QStyle::State_Selected) ==
QStyle::State_Selected);

QBrush baseBrush(sel ? option.palette.highlight() : option.palette.base());

QBrush textBrush(sel ? option.palette.highlightedText() :
option.palette.text());

 

QColor color = textBrush.color();

painter->setPen(QColor(0,102,255));

QStyledItemDelegate::paint(painter,option,index); 

Probably, because QStyledItemDelegate::paint itself sets the color of the
pen before painting, based on the style, the palette and the style sheet, I
guess.
