Hello.

A long time ago I tried to find method how to stick QDialog window to screen borders for my small projects like Skype windows do it, but I failed. May be I was looking this code not in the right place, so now I'm looking the solution here, on stack! :)

So, does any one have a deal with some kind of such code, links, samples?

In my opinion, we have to reimplement QDialog moveEvent function, like below, but that code does not working:

void    CDialog::moveEvent(QMoveEvent * event) {

    QRect wndRect;
    int leftTaskbar = 0, rightTaskbar = 0, topTaskbar = 0, bottomTaskbar = 0;
//  int top = 0, left = 0, right = 0, bottom = 0;

    wndRect = this->frameGeometry();

    // Screen resolution
    int screenWidth =   QApplication::desktop()->width();
    int screenHeight =  QApplication::desktop()->height();

    int wndWidth = wndRect.right() - wndRect.left();
    int wndHeight = wndRect.bottom() - wndRect.top();

    int posX = event->pos().x();
    int posY = event->pos().y();

    // Snap to screen border
    // Left border
    if (posX >= -m_nXOffset + leftTaskbar &&
        posX <= leftTaskbar + m_nXOffset) {
        //left = leftTaskbar;
        this->move(leftTaskbar, posY);
        return;
    }

    // Top border
    if (posY >= -m_nYOffset &&
        posY <= topTaskbar + m_nYOffset) {
        //top = topTaskbar;
        this->move(posX, topTaskbar);
        return;
    }

    // Right border
    if (posX + wndWidth <= screenWidth - rightTaskbar + m_nXOffset &&
        posX + wndWidth >= screenWidth - rightTaskbar - m_nXOffset) {
        //right = screenWidth - rightTaskbar - wndWidth;
        this->move(screenWidth - rightTaskbar - wndWidth, posY);
        return;
    }

    // Bottom border
    if (posY + wndHeight <= screenHeight - bottomTaskbar + m_nYOffset &&
        posY + wndHeight >= screenHeight - bottomTaskbar - m_nYOffset) {
        //bottom = screenHeight - bottomTaskbar - wndHeight;
        this->move(posX, screenHeight - bottomTaskbar - wndHeight);
        return;
    }

    QDialog::moveEvent(event);
}

Thanks.
