xtd::forms::button Class Reference

Inheritance diagram for xtd::forms::button:

Definition

Represents a Windows button control.

class forms_export_ button : public xtd::forms::ibutton_control, public xtd::forms::button_base

Inheritance

xtd::object → xtd::forms::component → xtd::forms::control → xtd::forms::button_base → xtd::forms::button

Implements

xtd::forms::ibutton_control

Header

#include <xtd/forms/button>

Namespace

xtd::forms

Library

xtd.forms

Remarks

A Button can be clicked by using the mouse, ENTER key, or SPACEBAR if the button has focus.

Set the accept_button or cancel_button property of a form to allow users to click a button by pressing the ENTER or ESC keys even if the button does not have focus. This gives the form the behavior of a dialog box.

When you display a form using the show_dialog method, you can use the dialog_result property of a button to specify the return value of show_dialog.

You can change the button's appearance. For example, to make it appear flat for a Web look, set the flat_style property to flat_style::flat. The flat_style property can also be set to flat_style::popup, which appears flat until the mouse pointer passes over the button; then the button takes on the standard Windows button appearance.

Note

If the control that has focus accepts and processes the ENTER key press, the button does not process it. For example, if a multiline text_box or another button has focus, that control processes the ENTER key press instead of the accept button.

Appearance

Gets the required creation parameters when the control handle is created.

Remarks

The create_params property should not be overridden and used to adjust the properties of your derived control. Properties such as the create_params::caption, create_params::width, and create_params::height should be set by the corresponding properties in your control such as control::text, control::width and control::height. The create_params should only be extended when you are wrapping a standard Windows control class or to set styles not provided by the forms namespace.

Notes for inheritors

When overriding the create_params property in a derived class, use the base class's create_params property to extend the base implementation. Otherwise, you must provide all the implementation.
