Problem with fill style

[hasmik]

Hello!!!

Please, look at attached pictures.
I want dispaly items on a grid texture. So mouse could move across discrete points. To obtain grid appearance I set view's background brush with pixmap.

view->setBackgroundBrush(QPixmap("Resources\\grid.png"));

view->setBackgroundBrush(QPixmap("Resources\\grid.png"));

To copy to clipboard, switch view to plain text mode 

But I met some problems. When I do zoom action the discrete points are zooming too. Item's fill texture spoilt too. But I want to zoom only GarphicsItems' sizes but not fillstyle and grid texture.

Please, give me advice to solve this problem.

one quick fix could be to set the background image in a style sheet with background-repeat option

Thank you for replying.

I never use style sheets.

Do you mean this?

view->setStyleSheet("QGraphicsView {background-image: url(Resources\\grid.png); "
		"background-repeat: repeat; }");

view->setStyleSheet("QGraphicsView {background-image: url(Resources\\grid.png); "
		"background-repeat: repeat; }");

To copy to clipboard, switch view to plain text mode 

What I've written wrong?

I understood why the image wasn't displayed. I should wrote QFrame instead of QGraphicsView.

view->setStyleSheet("QFrame { background-image: url(grid.png) ;"
				"background-repeat: repeat }");

view->setStyleSheet("QFrame { background-image: url(grid.png) ;"
				"background-repeat: repeat }");

To copy to clipboard, switch view to plain text mode 

But I don't understand what is doing background-repeat option.
Is it repeat background image without scaling??? (I don't think so)

Here I want to show how I do zoom operation.

void LayoutEditor::zoomIn()
{
	scaleFactor *= 1.25;
	view->scale(1.25, 1.25);
	if(scaleFactor >= 1.0) {
		// which function to use??????
		//view->setBackgroundBrush(QBrush(QPixmap("Resources\\grid.png")));
		//view->setStyleSheet("QFrame { background-image: url(grid.png) ;"
						"background-repeat: repeat }");
	}
	...
 
}
 
void LayoutEditor::zoomOut()
{
	scaleFactor *= 0.8;
	view->scale(0.8, 0.8);
	if(scaleFactor < 1.0) {
		view->setBackgroundBrush(QBrush(Qt::black));
	}	
	...
 
}

void LayoutEditor::zoomIn()
{
	scaleFactor *= 1.25;
	view->scale(1.25, 1.25);
	if(scaleFactor >= 1.0) {
		// which function to use??????
		//view->setBackgroundBrush(QBrush(QPixmap("Resources\\grid.png")));
		//view->setStyleSheet("QFrame { background-image: url(grid.png) ;"
						"background-repeat: repeat }");
	}
	...
		
}

void LayoutEditor::zoomOut()
{
	scaleFactor *= 0.8;
	view->scale(0.8, 0.8);
	if(scaleFactor < 1.0) {
		view->setBackgroundBrush(QBrush(Qt::black));
	}	
	...
	
}
