Sometimes it's necessary to change a state of TCheckBox component, but without operation of OnClick event. This task can be solved so: {set a checked}
yourCheckBox.Perform(BM_SETCHECK, 1, 0);
{set a unchecked}
yourCheckBox.Perform(BM_SETCHECK, 0, 0);
or else in one procedure
procedure ChangeChecked(ACheckBox: TCheckBox; AState: Boolean); begin ACheckBox.Perform(BM_SETCHECK, Ord(AState), 0); end;For example, if you will call the ChangeChecked(myCheckBox, True), then will be myCheckBox.Checked = True. |
