Dear all,
I want to do the following GUI element : a QLineEdit which popups when
some control is clicked, allowing the user for text input, and which
hides when enter is pressed, or when the user clicks outside the
QLineEdit.
How can this be implemented? In other words, I'm looking for an
undecorated floating widget (modal?) and getting an event when the
user clicked outside.
Thanks,
Etienne
Try popping up a QLineEdit with parent set to 0, and call this on it:
myLineEdit->setWindowFlags(Qt::ToolTip|Qt::Window);
You can also play around with other window flags of course. Obviously,
you will need to position the line edit before showing, relative to the
widget it is connected to. Take care that the coordinate system of a
widget with a parent is relative to its parent, while that of a a widget
without a parent is the global coordinate system. So, use
QWidget::mapToGlobal from your
widget-that-needs-to-show-a-popup-line-edit to get its global coordinates.
