QTable>>>paintCell

[:db:sStrong]

hello ppl,

I have reimplemented paintCell, i want to give the cells of my table a color.. i have 10 cells and i want that the 5 cells should get a color.. like the first cell white and the second yellow and the third white, fourth yellow .....

this is my code i am only able to color the 3 cells ...

void myTable::paintCell(QPainter *p, int row, int col, const QRect &cr, bool selected, const QColorGroup &cg)
{
 
	int numRows = this->numRows();
	int countRows = numRows;
 
	for(int i = 0; i < numRows ; i++)
 
		if (row == numRows-- || row == numRows+i || row == numRows-i || row == numRows+i
			|| row ==numRows-i)
		{
			QColorGroup colorGroup(cg);
			colorGroup.setColor(QColorGroup::Base, QColor("#ffffbb"));
			QTable::paintCell(p, row, col, cr, selected, colorGroup);
		}
		else
		{
			QTable::paintCell(p, row, col, cr, selected, cg);
		}
 
}

void myTable::paintCell(QPainter *p, int row, int col, const QRect &cr, bool selected, const QColorGroup &cg)
{
   
	int numRows = this->numRows();
	int countRows = numRows;

	for(int i = 0; i < numRows ; i++)
	
		if (row == numRows-- || row == numRows+i || row == numRows-i || row == numRows+i
			|| row ==numRows-i)
		{
			QColorGroup colorGroup(cg);
			colorGroup.setColor(QColorGroup::Base, QColor("#ffffbb"));
			QTable::paintCell(p, row, col, cr, selected, colorGroup);
		}
		else
		{
			QTable::paintCell(p, row, col, cr, selected, cg);
		}
	
}

if (row == numRows-- || ...

That -- looks very suspicious.

You don't need the for loop:

void myTable::paintCell(QPainter *p, int row, int col, const QRect &cr, bool selected, const QColorGroup &cg)
{
   QColorGroup colorGroup(cg);
   if( col % 2 == 1 ) {
      colorGroup.setColor(QColorGroup::Base, QColor("#ffffbb"));
   }
   QTable::paintCell(p, row, col, cr, selected, colorGroup);
}

void myTable::paintCell(QPainter *p, int row, int col, const QRect &cr, bool selected, const QColorGroup &cg)
{
   QColorGroup colorGroup(cg);
   if( col % 2 == 1 ) {
      colorGroup.setColor(QColorGroup::Base, QColor("#ffffbb"));
   }
   QTable::paintCell(p, row, col, cr, selected, colorGroup);
}
