paletteBackgroundColor()

[jpn]

ui.l1_le->setPaletteBackgroundColor("yellow");

QWidget::setPaletteBackgroundColor() is a Qt3 support member.



// set
QPalette palette = ui.l1_le->palette();
palette.setColor(ui.l1_le->backgroundRole(), Qt::yellow);
ui.l1_le->setPalette(palette);

// get
QColor color = ui.l1_le->palette().color(ui.l1_le->backgroundRole());


Instead of "ui.l1_le->backgroundRole()" you may also directly use QPalette::Base (http://doc.trolltech.com/4.2/qpalette.html#ColorRole-enum) which is used as a background role of text entry widgets.

Hello,

Thank you very much..

But how could i convert it to String?
For this for example:
QColor color = ui.l1_le->palette().color(ui.l1_le->backgroundRole());
QMessageBox::information(this,"LernIT",color);

I could solve my problem like that:

Thanks :D



QColor color = ui.l1_le->palette().color(ui.l1_le->backgroundRole());
//QMessageBox::information(this,"LernIT",QString::number(a));



if (color == "#ffff00")
insert();


else
solve();
