Detailed Description

Abstract base class for all modal dialogs.

A dialog shows a certain window instance to the user. The subclasses of this class will hold the parameters used for a certain window, eg a server connection dialog will hold the name of the selected server as parameter that way the caller doesn't need to know about the 'contents' of the window.

Usage

Simple dialogs that are shown to query user information it is recommended to add a static member called execute. The parameters to the function are:

references to in + out parameters by reference
references to the in parameters
the parameters for modal_dialog::show.

The 'in + out parameters' are used as initial value and final value when the OK button is pressed. The 'in parameters' are just extra parameters for showing.

When a function only has 'in parameters' it should return a void value and the function should be called display, if it has 'in + out parameters' it must return a bool value. This value indicates whether or not the OK button was pressed to close the dialog. See editor_new_map::execute for an example.

Saving only happens if a callback handler is installed.

Parameters

save_fields Does the value in the fields need to be saved?

Parameters

id	Id of the widget, same value as in WML.
mandatory	Is the widget mandatory or mandatory.
linked_variable	The variable the widget is linked to. See field::field for more information.
callback_change	When the value of the widget changes this callback is called.
initial_fire

Returns: Pointer to the created widget.

◆ register_label()

		const bool	mandatory,
		const std::string &	text,
		const bool	use_markup = `false`
	)

protected

Registers a new styled_widget as a label.

The label is used for a styled_widget to set the 'label' since it calls the styled_widget::set_label it can also be used for the image since there this sets the filename. (The use_markup makes no sense in an image but that's a detail.)

Note: In general it's preferred a widget sets its markup flag in WML, but some generic windows (like messages) may need different versions depending on where used.

Parameters

id	Id of the widget, same value as in WML.
mandatory	Is the widget mandatory or optional.
text	The text for the label.
use_markup	Whether or not use markup for the label.

◆ get_modal_dialog_id

Member Data Documentation

◆ allow_plugin_skip_

bool gui2::dialogs::modal_dialog::allow_plugin_skip_

private

Allow plugins to skip through the dialog? Most dialogs install a plugins context to allow plugins to accept whatever the dialog is offering and continue.

Some dialogs, especially those that install their own plugins context, may want to disable this.

Definition at line 373 of file modal_dialog.hpp.

◆ always_save_fields_

bool gui2::dialogs::modal_dialog::always_save_fields_

private

Always save the fields upon closing.

Normally fields are only saved when the retval::OK button is pressed. With this flag set is always saves. Be careful with the flag since it also updates upon canceling, which can be a problem when the field sets a preference.

◆ fields_

std::vector<std::unique_ptr<class field_base> > gui2::dialogs::modal_dialog::fields_

private

Contains the automatically managed fields.

Since the fields are automatically managed and there are no search functions defined we don't offer access to the vector. If access is needed the creator should store a copy of the pointer.

◆ focus_

std::string gui2::dialogs::modal_dialog::focus_

private

Contains the widget that should get the focus when the window is shown.

Referenced by init_fields(), and register_text().

◆ retval_

int gui2::dialogs::modal_dialog::retval_

private

The window's exit code (return value).

We keep a copy here so it may be accessed even after the dialog is closed and the window object is destroyed.

This value is initially set to 0 (retval::NONE) meaning the dialog was not shown. After show returns, it will hold the most recent retval of the window object, including any modifications made in post_show.

◆ show_even_without_video_

bool gui2::dialogs::modal_dialog::show_even_without_video_

private

Show the dialog even with –nogui? Some dialogs need to be shown even when –nogui is specified if the game is being driven by a plugin.

Those dialogs allow the plugin to styled_widget them by creating a plugin context in pre_show().
