How to get informations in QStyledItemDelegate?

qwe3

Hi,

I have my own QStyledItemDelegate and reiplementet paint() function on it. I need that delegate to use with my QCalendarWidget. And in standard QCalendarWidget weekend's days ( Saturday, Sunday ) are red. The rest days's color is black. I would like to get that information ( red / black color ) in that paint() function.

And the second information: I would like to know in paint() function, which day there is. But I need full date ( year, month, day ). The day I can get like this:

index.data(Qt::ItemDataRole());

I don't know why such stuff should be needed but you will need additional information from e.g. QCalenderWidget::currentPageChanged() to retrieve the month and year. Then you know the date and can draw something different for the specific days.

You can set the text format of your cells via QCalendarWidget::setWeekdayTextFormat(). There you can also set the desired background.

@Christian-Ehrlicher Thank you for your answer, but I think I don't underrstand something.

I need that color in paint() function like this ( pseudocode ):

   if( dayTextColor == "red")
  {
     painter->drawSomething;
  }
  else if(  dayTextColor == "black")
  {
     painter->drawOtherThing;
  }

And the same with the date.

Can you explain how to use QCalendarWidget::setWeekdatsTextFormat() to achieve that?
