The button will be visible by default. The application would show or
hide the button depending on the context.
Anyway, my actual modifications to TEditBtn just add the necessary logic
so that a descendant that can hide/show the button becomes feasible.
I think you mean component TCustomEditButton.
Indeed.
Your modification could be used for a filter-edit component I planned to make
and use for different list- and treeviews in Lazarus.
When empty, the control shows a gray "(filter)" or "(search)".
When user types something, an erase-button shows up. Clicking the button makes
the control empty again.
I wanted to draw an erase-button on the right end of the edit control itself,
but it may be more difficult.
Anyway, if you have modifications for TCustomEditButton which don't break
existing code, I think it can be used in LCL.
I think my modifications suit your exact needs. I'll submit the patch.
