TRadioButton.DialogChar function
Implements support for an accelerator key in the control.
Declaration
function DialogChar(var Message: TLMKey): Boolean; overrideArguments
Message | Message examined for the accelerator key. |
Function result
True when the message is handled and the control is focused and checked.Description
DialogChar is an overridden
Boolean function in
TRadioButton which handles accelerator keys in messages for the
control. The return value is set to
True when the radio button is
successfully toggled in the method.
Message is the TLMKey instance with the key code examined in the
method. If the key code matches the accelerator key in
Caption,
the control is focused, its Checked state is enabled, and the return value is
set to
True.
If the control cannot be focused, or Message does not represent the accelerator for the control, the inherited method is called to get the return value.
This method is called even if the control is disabled or hidden. Provided for Delphi VCL compatibility.
