get mousepress when widget is disabled (QLineEdit)

[mortoray]

I have some disabled controls that I want to emit a signal when they are clicked. The typical use is a QLineEdit which in some modes can be edited, and in others not. Clicking on it when disabled gives the use a prompt which allows them to enable the editing.

How can I get a mouse press event when the control is disabled?

Alternately, how can I make it just look disabled (not just read-only)?

Reimplement event() for the widget and handle the mouse event there.

Reimplement the paint event for the widget and change the style options passed to the style for drawing the widget.

A side note - from usability and user-friendliness perspective what you are trying to do is a very poor design. A much better approach would be to provide a checkbox near the line edit to enable or disable the widget.

That works. Thank you.

Agreed. In fact a single checkbox for the whole interface is all that is needed "[x] Advanced Controls". But alas, my powers of persuasion have failed me. :(

I'm having the same problem.
