TCustomControlFilterEdit.InternalSetFilter procedure
Performs actions needed when a new value is assigned to the Filter property.
Declaration
procedure InternalSetFilter(const AValue: string)Arguments
AValue | New filter value applied in the method. |
Description
InternalSetFilter is called from the write access specifier for the
Filter property. It performs actions needed when the value in
Filter has been changed (and applied to Text), and the control needs to be
updated to reflect the modified value.
- Sets the enabled state for the Button on the control; it is enabled when the AValue argument contains a non-empty value.
- Sets the values in members for the Filter and FilterLowercase properties.
- Calls Invalidatefilter to update internal members which cause the control to refresh the list of filtered items when an idle state occurs.
Added in LCL version 3.0.
