Signals to select Titles?
Hi all,
I know that I can interact with the mouse on the actual canvas, to select data, etc. Is it possible to link the QwtPlot directly to recognise a selection, click, double click on the graph titles or axis, so that the user could interactively select titles to update?
I know I could have a permenant dialogue box for changing these titles, but a pupop would be a neater solution.
Any ideas, or tips for other users out there?
Robbie

QwtPlot is a composite widget. All of its children are available using getter methods. So you can install event filters to handle all mouse/wheel/key events on them.
On the canvas you also have QwtPlotPicker, that offers a visual feedback for your selections and returns the selection in plot coordinates.
