TTaskDialog is a non-visual component, which shows full-featured dialogs at runtime, dialogs with rich features like Windows TaskDialog API has. It is available under the Dialogs of the Component Palette.
Dialog is shown with the Execute() method, and if it gets True, property ModalResult has id of pressed button:
- id of standard button (OK, Cancel, Yes etc)
- id of custom button, which is specified in each button's ModalResult
Also, property RadioButton has the radio-button object, which was clicked.
This example shows how to create dialog in runtime, and to add custom buttons in runtime:
with TTaskDialog.Create(self) do
try
Title := 'Confirm removal';
Caption := 'Confirm';
Text := Format('Are you sure that you want to remove the book file named "%s"?', [FNameOfBook]);
CommonButtons := [];
with TTaskDialogButtonItem(Buttons.Add) do
begin
Caption := 'Remove';
ModalResult := mrYes;
end;
with TTaskDialogButtonItem(Buttons.Add) do
begin
Caption := 'Keep';
ModalResult := mrNo;
end;
MainIcon := tdiNone;
if Execute then
if ModalResult = mrYes then
DoDelete;
finally
Free;
end;
