TTaskDlgTimerEvent procedure type
Specifies an event handler signalled when the timer callback is enabled in a task dialog.
Declaration
TTaskDlgTimerEvent = procedure(Sender: TObject; TickCount: Cardinal;
var Reset: Boolean) of objectArguments
Sender | Task dialog for the event notification. |
TickCount | Number of ticks (milliseconds) since the timer was started. |
Reset | Set to True to reset the timer. Set to False to continue execution of the timer callback. |
Description
TTaskDlgTimerEvent is an object procedure type which defines an
event handler signalled when the timer internal in a task dialog has elapsed.
Applications can implement and assign a routine using the signature for the
type to the OnTimer event handler in TTaskDialog.
The routine is signalled from the DoOnTimer method in TCustomTaskDialog and is called periodically from the widgetset class when the callback timer is enabled in the task dialog. Arguments passed to the routine indicate the dialog form for the event notification, the number of ticks (milliseconds) since the timer was started, and an updatable value to indicate that the time should be reset.
Added in LCL version 4.0.
