QTableWidget - How to set background-color with widget

SGaist

Hi,

Can you share the code you use to setup the background color and widgets ?

fgdevel

yes of course :

[...]
tableItem = new QTableWidgetItem("");
tableItem->setFlags(tableItem->flags() & ~(Qt::ItemIsEditable));
//Add Table items here With Default Cell Texts
ui->tableWidget->setItem(y,0,new QTableWidgetItem(""));
ui->tableWidget->setItem(y,1,tableItem);
ui->tableWidget->setItem(y,2,new QTableWidgetItem(""));
ui->tableWidget->setCellWidget(y,3,new QCheckBox(""));
ui->tableWidget->setCellWidget(y,4,new QCheckBox(""));
ui->tableWidget->setCellWidget(y,5,new QCheckBox(""));
[...]

The background-color works only for "QTableWidgetItem" cells (without widget)

SGaist

When you set a cell widget you don't see the item underneath (and you don't have any under), you have to set the background on the widget itself.

@SGaist

is there any global function to set the background-color ? (which works with or without widget...) ?

SGaist

You can try by modifying the palette of the application.

@SGaist

I want to modify a specific TableWidget and not all grids or all widget contained in the application...Have you an example ?

SGaist

You want to modify only that widget and all its children ?

fgdevel

@SGaist

I want to modify all cells of QTableWidget, several cells contain QTableWidgetItem, several cells contain QCheckbox for example

SGaist

Then you can write the style sheet so that it applies to both your QTableWidget and its children widgets

fgdevel

@SGaist

It seems to work on QTableWidget but not on children widgets when I set the style sheet

fgdevel

I have resolved my problem with :

ui->tableWidget->item(i,j)->setBackground(Qt::gray);
