HowTo stick QDialog to Screen Borders like Skype do?
- by mosg
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.
