![]() ![]() The Caption property can be used to define an accelerator key to the control. For example, two radio buttons on a form can be checked at the same time only if they are contained in separate containers, such as two different group boxes. Or you can add a TRadioGroup, a group that already has radio buttons in it, so that you do not have to get the buttons from the Tool Palette.īy default, all radio buttons that are directly contained in the same windowed control container, such as a TRadioGroup or TPanel, are grouped. Properties provide control over access to an objects attributes, and they allow attributes to be computed. Add the group box to the form first, then get the radio buttons from the Component palette and put them into the group box. Radio buttons are frequently grouped in a radio group box (TGroupBox). When the user selects a radio button, the previously selected radio button becomes unselected. Radio buttons present a set of mutually exclusive options to the user- that is, only one radio button in a set can be selected at a time.

If tfVerificationFlagChecked in TTaskDialog(Sender).Flags then Procedure TForm1.TaskDialogVerificationClicked(Sender: TObject) OnVerificationClicked := TaskDialogVerificationClicked VerificationText := 'Remember my settings.' Text := 'Do you want to continue with settings?' OnVerificationClicked event, which is triggered every time the state of the checkbox is changed during the modality of the dialog. For example, imagine a check box within a group box. You can make the checkbox initially checked by setting the tfVerificationFlagChecked flag. The caption of the checkbox is the property. Using the VerificationText string property, you can add a checkbox to the footer of the task dialog. If TTaskDialog(Sender).Button.Index=0 then ModalResult: TModalResult var CanClose: Boolean) Procedure TForm1.TaskDialogButtonClicked(Sender: TObject Initially, the tab order is always the order in which the controls were added to the form. The control with the TabOrder value of 0 is the control that has the focus when the form first appears. OnButtonClicked := TaskDialogButtonClicked Description TabOrder is the order in which child windows are visited when the user presses the Tab key. With TTaskDialogButtonItem(Buttons.Add) do Mida is a complete converter of Embarcadero Delphi and C++ Builder VCL applications to. Procedure TForm1.btnShowTaskDialogClick(Sender: TObject) We can also implement custom button click event which will fire on custom button click.
