My best wishes for the new year
I am trying to have items in a TTMSFNCListbox that can have a height from 0 to whatever its content needs.
I set the ItemsAppearance → heightMode = lihmvariable and fixedheight to 0 or -1 but this does no seem to work except with wordwrapping checked and have higher items.
The default item size can not be changed
My initial intention was to have items that can be unvisible (height=0) or the height that all item’s text is visible
That’s unfortunately not possible. The minimum variable item height can be set to 1, 0 will not be accepted, since it automatically calculates the start & end position of the item based on the height. For performance reasons, it does not loop through all items, it uses a base height
TMSFNCListBox1.TreeView.NodesAppearance.VariableMinimumHeight := 0.000001;
It will still allow you to select the item even though it’s pratically a zero height item. You would need to disable selecting it with
TMSFNCListBox1.Items[0].Enabled := False;
And then also change the disabledfill to make it “invisible”.
