I'd like to use TElXTree as a grid with some calculated columns. Therefore I need not only to disable the editing ability for some columns, but also to disable their focusing by mouse or keyboard. For example: I have 5 columns - the first four contain editable numbers, and the fifth contain some result.
And I'd like to be able to control the cell selection: the first four columns are selectable, but nothing should happen when user clicks any cell in the fifth column. Selection/focus ring shouldn't move.
I can't find any suitable event handlers. Is this yet possible?
Some modified files (ElXTreeHeader.pas and ELXTree.pas) were sent to email@example.com
