    Default Absolute widget coordinates

    The x() and y() functions return the relative coordinates of a widget to its parent. Is there a simple way to find the absolute coordinates of a widget in a window (rather than iterating up parents to the window)?

    thanks, Richard

    you can use QWidget::mapToGlobal(const QPoint & pos) which gives you pos translated to global coordinates
    I would like to be a "Guru"

    Useful hints (try them before asking):
    1. Use Qt Assistant
    2. Search the forum

    If you haven't found solution yet then create new topic with smart question.

    thanks for the reply faldżip.
    Unfortunately mapToGlobal() gives the result in screen coordinates, meaning that it is dependent on the location of the window.

    Try this:
    Qt Code:
    1. QPoint localPoint = ...
    2. QPoint windowPoint = myWidget->mapTo(myWidget->window(), localPoint);
    To copy to clipboard, switch view to plain text mode 

    It's probably equivalent to:
    Qt Code:
    1. QPoint mapToWindow(QWidget *from, QPoint pt){
    2. QWidget *wnd = from->window();
    3. while(from && from!=wnd){
    4. pt = from->mapToParent(pt);
    5. from = from->parent();
    6. }
    7. return pt;
    8. }
    To copy to clipboard, switch view to plain text mode
