Description

TEmulatedTaskDialog is a TForm descendant which implements the form displayed for an emulated task dialog. It provides a LCL implementation of the task dialog. It is used when a native task dialog implementation is not available, or is explicitly requested when a task dialog is executed.

TLabels instances are used to represent the visual elements on the dialog as defined in the TTaskDialogElement enumeration.

It provides a TComboBox used for a selection list, a TEdit control used for query input, and a TCheckBox used for the verification text.

There are restrictions to the task dialog flags used on an emulated task dialog. Only the tdfUseCommandLinks, tdfUseCommandLinksNoIcon, and tdfQuery flag options are supported. Other values passed requested in the caller are ignored for an emulated task dialog.

Use the aNonNative argument in the TTaskDialog.Execute method to specify use of an emulated task dialog at run-time.

TTaskDialog.Execute		Launches the task dialog form.
TTaskDialogElement		Represents visual elements which can be displayed on a task dialog.
TTaskDialogFlag		Contains flags used to control the display and behavior of a task dialog.
TTaskDialogFlags		Set type used to store values from the TTaskDialogFlag enumeration.
TTaskDialog.Execute		Launches the task dialog form.
TForm		Implements a form used in an LCL application.
