TCustomTaskDialog.OnRadioButtonClicked property

Declaration

property OnRadioButtonClicked: TNotifyEvent read FOnRadioButtonClicked write FOnRadioButtonClicked;

Description

OnRadioButtonClicked is a TNotifyEvent property with the event handler signalled when a radio button on the task dialog has been clicked. It is signalled (when assigned) from the DoOnRadioButtonClicked method, and occurs after the value in RadioButton has been updated to reflect the button identifier clicked on the dialog form.

For native implementations using the Task Dialog API (supported Windows versions), it occurs when the TDN_RADIO_BUTTON_CLICKED notification is handled in the callback routine for the class instance. For emulated task dialog forms, it occurs when the corresponding event handler implementation for the LCL form instance is called.

Added in LCL version 4.0.
