QPalette won't set QLabel's Window & Foreground color

[koklim]

Hi, i am using qt 4.1.0 on a window xp platform. I use the appraoch below to set the label's forefround and Window color but nothing happens. I have serch every where for clues to solve this but to no avale. I greatly appreciate any help. Thanks

QPalette temp;
temp.setColor(QPalette::Foreground, QColor(255, 0, 0));
temp.setColor(QPalette::Window, QColor(0, 0, 0));

for (int i = 0; i < iColSize; i++)
{
ptrLbl = new QLabel(this);
ptrLbl->setObjectName("XXX");
ptrLbl->setGeometry( X,X,X,X );
ptrLbl->setFrameShape( QFrame::StyledPanel );
ptrLbl->setAlignment( int( Qt::AlignLeft ) );
ptrLbl->setMouseTracking(true);

ptrLbl->setPalette(temp);
}

at the end you must show your label

ptrLbl->show();

ptrLbl->show();

To copy to clipboard, switch view to plain text mode

it didn't work. Just found out that it must be something more.

Does it work when you use different style?

C:\...> app.exe -style plastique

C:\...> app.exe -style plastique

Two problems:
1) QPalette::Foreground is deprecated, use WindowText instead.
2) A label does not have a background in Qt4.1, only the text is drawn. To fill the background automatically you can use setAutoFillBackground(true) on your labels.

QPalette temp;
 temp.setColor(QPalette::WindowText, QColor(255, 0, 0)); 
 temp.setColor(QPalette::Window, QColor(0, 0, 0));
 
 for (int i = 0; i < iColSize; i++) 
 {
 ptrLbl = new QLabel(this);
 ptrLbl->setObjectName("XXX"); 
 ptrLbl->setAutoFillBackground( true );
 ptrLbl->setGeometry( X,X,X,X ); 
 ptrLbl->setFrameShape( QFrame::StyledPanel );
 ptrLbl->setAlignment( int( Qt::AlignLeft ) );
 ptrLbl->setMouseTracking(true);
 
 ptrLbl->setPalette(temp);
 }

QPalette temp;
 temp.setColor(QPalette::WindowText, QColor(255, 0, 0)); 
 temp.setColor(QPalette::Window, QColor(0, 0, 0));
 
 for (int i = 0; i < iColSize; i++) 
 {
 ptrLbl = new QLabel(this);
 ptrLbl->setObjectName("XXX"); 
 ptrLbl->setAutoFillBackground( true );
 ptrLbl->setGeometry( X,X,X,X ); 
 ptrLbl->setFrameShape( QFrame::StyledPanel );
 ptrLbl->setAlignment( int( Qt::AlignLeft ) );
 ptrLbl->setMouseTracking(true);
 
 ptrLbl->setPalette(temp);
 }

Hope this helps.
