Struct AppChooserDialog 

pub struct AppChooserDialog { /* private fields */ }

👎Deprecated:

Since 4.10

The application selection widgets should be implemented according to the design of each platform and/or application requiring them. AppChooserDialog shows a AppChooserWidget inside a Dialog.

Note that AppChooserDialog does not have any interesting methods of its own. Instead, you should get the embedded AppChooserWidget using widget() and call its methods if the generic AppChooser interface is not sufficient for your needs.

To set the heading that is shown above the AppChooserWidget, use set_heading().

CSS nodes

AppChooserDialog has a single CSS node with the name window and style class .appchooser.

Properties

gfile

The GFile used by the AppChooserDialog.

The dialog’s AppChooserWidget content type will be guessed from the file, if present.

Readable | Writable | Construct Only

heading

The text to show at the top of the dialog.

The string may contain Pango markup.

Readable | Writable

Dialog

use-header-bar

true if the dialog uses a headerbar for action buttons instead of the action-area.

For technical reasons, this property is declared as an integer property, but you should only set it to true or false.

Creating a dialog with headerbar

Builtin Dialog subclasses such as ColorChooserDialog set this property according to platform conventions (using the gtk-dialogs-use-header setting).

Here is how you can achieve the same:

⚠️ The following code is in c ⚠️

g_object_get (settings, "gtk-dialogs-use-header", &header, NULL);
dialog = g_object_new (GTK_TYPE_DIALOG, header, TRUE, NULL);

Readable | Writable | Construct Only

Window

application

The Application associated with the window.

The application will be kept alive for at least as long as it has any windows associated with it (see g_application_hold() for a way to keep it alive without windows).

Normally, the connection between the application and the window will remain until the window is destroyed, but you can explicitly remove it by setting the this property to NULL.

Readable | Writable

child

The child widget.

Readable | Writable

decorated

Whether the window should have a frame (also known as decorations).

Readable | Writable

default-height

The default height of the window.

Readable | Writable

default-widget

The default widget.

Readable | Writable

default-width

Readable | Writable

destroy-with-parent

If this window should be destroyed when the parent is destroyed.

Readable | Writable

display

This property is maintained by GTK based on user input and should not be set by applications.

Readable | Writable

focus-widget

The focus widget.

Readable | Writable

fullscreened

Whether the window is fullscreen.

Setting this property is the equivalent of calling GtkWindowExt::fullscreen() or GtkWindowExt::unfullscreen(); either operation is asynchronous, which means you will need to connect to the ::notify signal in order to know whether the operation was successful.

Readable | Writable

gravity

The gravity to use when resizing the window programmatically.

Gravity describes which point of the window we want to keep fixed (meaning that the window will grow in the opposite direction). For example, a gravity of GTK_WINDOW_GRAVITY_TOP_RIGHT means that we want the to fix top right corner of the window.

Readable | Writable

handle-menubar-accel

Whether the window frame should handle F10 for activating menubars.

Readable | Writable

hide-on-close

If this window should be hidden instead of destroyed when the user clicks the close button.

Readable | Writable

icon-name

Specifies the name of the themed icon to use as the window icon.

See IconTheme for more details.

Readable | Writable

is-active

Whether the toplevel is the currently active window.

Readable

maximized

Whether the window is maximized.

Setting this property is the equivalent of calling GtkWindowExt::maximize() or GtkWindowExt::unmaximize(); either operation is asynchronous, which means you will need to connect to the ::notify signal in order to know whether the operation was successful.

Readable | Writable

mnemonics-visible

Whether mnemonics are currently visible in this window.

This property is maintained by GTK based on user input, and should not be set by applications.

Overrides for height request of the widget.

If this is -1, the natural request will be used.

Readable | Writable

Whether to expand horizontally.

Readable | Writable

This property is meant to be set by widget implementations, typically in their instance init function.

Readable | Writable

limit-events

Makes this widget act like a modal dialog, with respect to event delivery.

Global event controllers will not handle events with targets inside the widget, unless they are set up to ignore propagation limits. See EventControllerExt::set_propagation_limit().
