xtd::forms::common_dialog Class Reference

Inheritance diagram for xtd::forms::common_dialog:

Definition

Specifies the base class used for displaying dialog boxes on the screen.

Header

#include <xtd/forms/common_dialog>

xtd.forms

Remarks

Inherited classes are required to implement run_dialog by invoking show_dialog to create a specific common dialog box. Inherited classes can optionally override hook_proc to implement specific dialog box hook functionality.

Constructor & Destructor Documentation

common_dialog()

xtd::forms::common_dialog::common_dialog

(

)

Initializes a new instance of the common_dialog class.

Member Function Documentation

dialog_result()

xtd::forms::dialog_result xtd::forms::common_dialog::dialog_result ( ) const

noexcept

Gets async dialog_result result after dialog box is closing.

Returns

ok if the user clicks OK in the dialog box; otherwise, cancel.

tag() [1/2]

std::any xtd::forms::common_dialog::tag ( ) const

noexcept

Gets an object that contains data about the control.

Returns

The object that contains data about the common_dialog.

Remarks

Use this property to store arbitrary information about the control.

tag() [2/2]

common_dialog & xtd::forms::common_dialog::tag

(

const std::any &

tag

)

Sets an object that contains data about the control.

Parameters

tag	The object that contains data about the common_dialog.

Remarks

Use this property to store arbitrary information about the control.

reset()

virtual void xtd::forms::common_dialog::reset ( )

pure virtualnoexcept

When overridden in a derived class, resets the properties of a common dialog box to their default values.

Notes to Inheritors

Inheriting classes can override this method to reset their properties.

Implemented in xtd::forms::color_dialog, xtd::forms::file_dialog, xtd::forms::folder_browser_dialog, xtd::forms::font_dialog, and xtd::forms::input_dialog.

show_dialog() [1/2]

xtd::forms::dialog_result xtd::forms::common_dialog::show_dialog

(

)

Runs a common dialog box with a default owner.

Returns

ok if the user clicks OK in the dialog box; otherwise, cancel.

Remarks

This method implements run_dialog.

Examples

demo.cpp, input_dialog_multiline.cpp, and painting.cpp.

show_dialog() [2/2]

xtd::forms::dialog_result xtd::forms::common_dialog::show_dialog

ok the user clicks OK in the dialog box; otherwise, cancel.

Remarks

This version of the show_dialog method allows you to specify a specific form or control that will own the dialog box that is shown. If you use the version of this method that has no parameters, the dialog box being shown would be owned automatically by the currently active window of your application.

virtual void xtd::forms::common_dialog::on_help_request ( help_event_args &  e )

protectedvirtual

Raises the common_dialog::help_request event.

Parameters

e	An xtd::forms::help_event_args that provides the event data.

virtual bool xtd::forms::common_dialog::run_dialog ( intptr  hwnd_owner )

protectedpure virtual

When overridden in a derived class, specifies a common dialog box.

Parameters

hwnd_owner

A value that represents the window handle of the owner window for the common dialog box.

Remarks

The result will done in async. Check result_dialog property after dialog box closed to obtain the result.

Implemented in xtd::forms::file_dialog, xtd::forms::color_dialog, xtd::forms::folder_browser_dialog, xtd::forms::font_dialog, and xtd::forms::input_dialog.
