TCustomDBComboBox.WndProc procedure
Handles cut, copy and paste window messages for the control.
Declaration
procedure WndProc(var Message: TLMessage); overrideArguments
Message | LCL window message examined in the method. |
Description
WndProc is an overridden method in
TCustomDBComboBox.
WndProc ensures that LCL Cut, Copy, and Paste window messages are applied
when both the control and the dataset can be modified. WndProc uses the
internal
TFieldDataLink instance to examine the value in
CanModify. When it is
True, the inherited method is called.
Otherwise, the Message result is set to 1 to prevent calling the default
window process.
The inherited method is called for LCL window messages other than Cut, Copy, and Paste.
