TCustomComboBox.RealSetText

Updates ItemIndex when the new value for the control is updated.

Declaration

Source position: stdctrls.pp line 386

protected procedure TCustomComboBox.RealSetText(

  const AValue: TCaption

); override;

Arguments

AValue

  

The new value for the control.

Description

RealSetText is an overridden method in TCustomComboBox. It ensures that ItemIndex is updated with the ordinal position in Items where the AValue argument is found. If there are no values stored in Items, ItemIndex is set to -1. A visible emulated TextHint is hidden when AValue is not an empty string ('').

The inherited method is called prior to exit. This causes the widgetset class to be updated when its Handle is valid. The value in Caption is also updated, and a CM_TEXTCHANGED control message is performed for the control.
