Class TSampleTreeSelect (unit TestSelectForm) |
This is a sample-TTreeSelect-form with two buttons. The first button shows how to clear the key-field. The second button calls a dialog that allows the user to edit the detail-table. The OnActivate-event is used to adjust the size of the TreeView and the buttons at runtime. The height of the form changes if DropdownHeight of the calling DbTreeLookupComboBox is not zero, the width changes always at runtime.
