Qt developers! Is there are way to add image on the background of my midArea like on picture below?
I know I can use something like this
QImage img("logo.jpg");
mdiArea->setBackground(img);
But I don't need any repeat of my image on the background.
Thank you!
As I said in my comment above, you can sub-class the QMdiArea, override its paintEvent() function and draw your logo image yourself (in the bottom right corner). Here is the sample code that implements the mentioned idea:
class MdiArea : public QMdiArea
{
public:
MdiArea(QWidget *parent = 0)
:
QMdiArea(parent),
m_pixmap("logo.jpg")
{}
protected:
void paintEvent(QPaintEvent *event)
{
QMdiArea::paintEvent(event);
QPainter painter(viewport());
// Calculate the logo position - the bottom right corner of the mdi area.
int x = width() - m_pixmap.width();
int y = height() - m_pixmap.height();
painter.drawPixmap(x, y, m_pixmap);
}
private:
// Store the logo image.
QPixmap m_pixmap;
};
And finally use the custom mdi area in the main window:
int main(int argc, char *argv[])
{
QApplication app(argc, argv);
QMainWindow mainWindow;
QMdiArea *mdiArea = new MdiArea(&mainWindow);
mainWindow.setCentralWidget(mdiArea);
mainWindow.show();
return app.exec();
}
