QTableView stylesheet

Giovanna

Hi all,
I have a problem with the stylesheet I'd like to use for a tableview containing three columns and several rows. If a call the setStyleSheet function inside the panel constructor containing the tableview it doesn't work and the tableview is not populated even if i call the setModel function. (i have to set the style of indicator if it is checked or unchecked using images). If I call the setStyleSheet function when I open the panel containing the tableview, it works but it
causes a slowing down of the application.
Can you help me?
Thank you

Hi and welcome to devnet,

Can you show your stylesheet ? And the way you use it ?

Hi,
I explain better the problem. I have a tableview in a qwidget containing one column with strings and two column with checkboxes. I'd like to change the style of checkbox. So, i tried to set the stylesheet calling the function setStyleSheet in the widget constructor:

tableViewStyle.append("QTableView::indicator{background-color: transparent;}");
	tableViewStyle.append("QTableView::indicator:unchecked{background-color: transparent;}");
	tableViewStyle.append("QTableView::indicator:checked{image:url(:/new/MainWinImages/Images/V.PNG);}");
	tableViewStyle.append("QTableView::indicator{width:40px;height:40px;}");
	tableViewStyle.append("QTableView::indicator{margin-left:20%; margin-right:50%;}");
	tableViewStyle.append("QTableView{background-color: rgb(149, 199, 236);}");
		tableViewStyle.append("QTableView::indicator{width:40px;height:40px;}");
	tableViewStyle.append("QTableView::indicator{margin-left:20%; margin-right:50%;}");
	tableViewStyle.append("QTableView{background-color: rgb(149, 199, 236);}");

	m_ui->tableView->setEditTriggers(QAbstractItemView::NoEditTriggers);

	m_ui->tableView->setStyleSheet(tableViewStyle);

I call the function setModel in the constructor too passing a reimplemented model. I notice that when I open the panel containing the tableview the function data of the model that populate the tableview is not called and the stylesheet has no effect. Instead, if I set the stylesheet when I open the panel and not in the constructor, everything work fine but I notice the application slows down., maybe because the stylesheet is heavy.

It depends on the number of style sheet and their size but yes heaving customisation can trigger some slowdowns.

For the reason i Tried to call the function to set the stylesheet at the beginning, when the application is loading. Why the list is not populated if i set the stylesheet in the constructor?

I don't know, I don't have access to the code to check.
