Button clicks lost if node is being edited

[mpfj]

Delphi 12.2
VTV - current git master

If you are editing a node in the tree and you click away from that edit box onto (say) a standard button, the edit box closes but the button click never occurs.

This is contrary to how the standard Win32 treeview works ... this closes the edit box, applies the new text and then also clicks the button (which is how myself and my colleagues perceive the control should work).

To demonstrate this:-

• Load up, compile and run the "Minimal" demo
• Click on the first node "Level 0, Index 0"
• Press F2 to enter Edit Mode
• Now click the "Clear tree" button at the bottom

You will see that the edit box closes but the tree is not cleared.
Somewhere the "click the button" message is being lost when the edit box closes.

This is contrary to how the standard Win32 treeview works

I cannot confirm this. I just tried this in the File-Open-Dialog of Delphi, both with the treeview and the listview: Selecting an element, pressing F2 and then clicking the Open or Cancel button does nothing. I am on Windows 11. Can you confirm this?

No, when I using the following code, I get a TreeView on which I can double-click the nodes to start editting the text.
Once in edit mode, you can click the Button and the message box pops up.

This is not how VTV seems to work ... the Button press is ignored until the edit has finished so you have to click twice.

Have you tried in the File-Open-dialog?

[mpfj]

Yes and, as you say, the OK and Cancel clicks are ignored until the edit box is ended.

So I guess what I'm asking is which behaviour is "correct" ?
As with many things Windows based, nothing is consistent :(
