Click on icon in TComboBox
« on: May 22, 2011, 06:11:58 pm »
Hi all.

How to handle a click on the icon in the csOwnerDraw TComboBox? I need to when click on the icon to prohibit the selection item is clicked or collapse the list.

Sorry for my english((

Do you mean something like CheckBoxes in TComboBox ?

I think it is impossible with TComboBox.
The most similar thing I found in Lazarus: Tools -> Configure Build Lazarus ... (done by THeaderControl + TListBox)
You will probably have to do it by combonation of TEdit + TListBox (and you will show/hide TListBox).
Or possibly you can use one TStringGrid or TDrawGrid and change its height (one row / more rows).
And of course you will have to draw your own icons using OnDrawItem events.
At this time I have no idea for simplier solution.
