Struct AppChooserDialog 

Source 
pub struct AppChooserDialog { /* private fields */ }
Expand description

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 AppChooserDialogExt::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 AppChooserDialogExt::set_heading().

§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.

Readable | Writable | Construct Only

Window
§accept-focus

Whether the window should receive the input focus.

Readable | Writable

§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 ApplicationExtManual::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 :application property to None.

Readable | Writable

§attached-to

The widget to which this window is attached. See GtkWindowExt::set_attached_to().

Examples of places where specifying this relation is useful are for instance a Menu created by a ComboBox, a completion popup window created by Entry or a typeahead search entry created by TreeView.

Readable | Writable | Construct

§decorated

Whether the window should be decorated by the window manager.

Source§

fn add(&self, widget: &impl IsA<Widget>)

Adds widget to self. Typically used for simple containers such as Window, Frame, or Button; for more complicated layout containers such as Box or Grid, this function will pick default packing parameters that may not be correct. So consider functions such as BoxExt::pack_start() and GridExt::attach() as an alternative to add() in those cases. A widget may be added to only one container at a time; you can’t place the same widget inside two different containers. Read more

Source§

fn foreach<P: FnMut(&Widget)>(&self, callback: P)

Invokes callback on each non-internal child of self. See forall() for details on what constitutes an “internal” child. For all practical purposes, this function should iterate over precisely those child widgets that were added to the container by the application with explicit add() calls. Read more

fn propagate_draw(&self, child: &impl IsA<Widget>, cr: &Context)

When a container receives a call to the draw function, it must send synthetic draw calls to all children that don’t have their own GdkWindows. This function provides a convenient way of doing this. A container, when it receives a call to its draw function, calls propagate_draw() once for each child, passing in the cr the container received. Read more

fn remove(&self, widget: &impl IsA<Widget>)

Removes widget from self. widget must be inside self. Note that self will own a reference to widget, and that this may be the last reference held; so removing a widget from its container can destroy that widget. If you want to use widget again, you need to add a reference to it before removing it from a container, using g_object_ref(). If you don’t want to use widget again it’s usually more efficient to simply destroy it directly using gtk_widget_destroy() since this will remove it from the container and help break any circular reference count cycles.

fn iconify(&self)

Asks to iconify (i.e. minimize) the specified self. Note that you shouldn’t assume the window is definitely iconified afterward, because other entities (e.g. the user or [window manager][gtk-X11-arch]) could deiconify it again, or there may not be a window manager in which case iconification isn’t possible, etc. But normally the window will end up iconified. Just don’t write code that crashes if not. Read more

fn is_active(&self) -> bool

Returns whether the window is part of the current active toplevel. (That is, the toplevel window receiving keystrokes.) The return value is true if the window is active toplevel itself, but also if it is, say, a Plug embedded in the active toplevel. You might use this function if you wanted to draw a widget differently in an active window from a widget in an inactive window. See has_toplevel_focus() Read more

fn move_(&self, x: i32, y: i32)

Asks the [window manager][gtk-X11-arch] to move self to the given position. Window managers are free to ignore this; most window managers ignore requests for initial window positions (instead using a user-defined placement algorithm) and honor requests after the window has already been shown. Read more
Source§

fn present(&self)

Presents a window to the user. This function should not be used as when it is called, it is too late to gather a valid timestamp to allow focus stealing prevention to work correctly.

fn present_with_time(&self, timestamp: u32)

Presents a window to the user. This may mean raising the window in the stacking order, deiconifying it, moving it to the current desktop, and/or giving it the keyboard focus, possibly dependent on the user’s platform, window manager, and preferences. Read more
Source§

fn propagate_key_event(&self, event: &EventKey) -> bool

Propagate a key press or release event to the focus widget and up the focus container chain until a widget handles event.

fn resize(&self, width: i32, height: i32)

Resizes the window as if the user had done so, obeying geometry constraints. The default geometry constraint is that windows may not be smaller than their size request; to override this constraint, call WidgetExt::set_size_request() to set the window’s request to a smaller value. Read more

Source§

fn set_attached_to(&self, attach_widget: Option<&impl IsA<Widget>>)

Marks self as attached to attach_widget. This creates a logical binding between the window and the widget it belongs to, which is used by GTK+ to propagate information such as styling or accessibility to self as if it was a children of attach_widget. Read more
Source§

fn set_decorated(&self, setting: bool)

By default, windows are decorated with a title bar, resize controls, etc. Some [window managers][gtk-X11-arch] allow GTK+ to disable these decorations, creating a borderless window. If you set the decorated property to false using this function, GTK+ will do its best to convince the window manager not to decorate the window. Depending on the system, this function may not have any effect when called on a window that is already visible, so you should call it before calling WidgetExt::show(). Read more
Source§

fn set_default(&self, default_widget: Option<&impl IsA<Widget>>)

The default widget is the widget that’s activated when the user presses Enter in a dialog (for example). This function sets or unsets the default widget for a Window. When setting (rather than unsetting) the default widget it’s generally easier to call WidgetExt::grab_default() on the widget. Before making a widget the default widget, you must call WidgetExt::set_can_default() on the widget you’d like to make the default. Read more
Source§

fn set_default_size(&self, width: i32, height: i32)

Sets the default size of a window. If the window’s “natural” size (its size request) is larger than the default, the default will be ignored. More generally, if the default size does not obey the geometry hints for the window (set_geometry_hints() can be used to set these explicitly), the default size will be clamped to the nearest permitted size. Read more
Source§

fn set_deletable(&self, setting: bool)

By default, windows have a close button in the window frame. Some [window managers][gtk-X11-arch] allow GTK+ to disable this button. If you set the deletable property to false using this function, GTK+ will do its best to convince the window manager not to show a close button. Depending on the system, this function may not have any effect when called on a window that is already visible, so you should call it before calling WidgetExt::show(). Read more
Source§

fn set_destroy_with_parent(&self, setting: bool)

If setting is true, then destroying the transient parent of self will also destroy self itself. This is useful for dialogs that shouldn’t persist beyond the lifetime of the main window they’re associated with, for example. Read more
Source§

fn set_focus(&self, focus: Option<&impl IsA<Widget>>)

If focus is not the current focus widget, and is focusable, sets it as the focus widget for the window. If focus is None, unsets the focus widget for this window. To set the focus to a particular widget in the toplevel, it is usually more convenient to use WidgetExt::grab_focus() instead of this function. Read more

Source§

fn set_hide_titlebar_when_maximized(&self, setting: bool)

If setting is true, then self will request that it’s titlebar should be hidden when maximized. This is useful for windows that don’t convey any information other than the application name in the titlebar, to put the available screen space to better use. If the underlying window system does not support the request, the setting will not have any effect. Read more
Source§

fn set_icon(&self, icon: Option<&Pixbuf>)

Sets up the icon representing a Window. This icon is used when the window is minimized (also known as iconified). Some window managers or desktop environments may also place it in the window frame, or display it in other contexts. On others, the icon is not used at all, so your mileage may vary. Read more

fn set_keep_above(&self, setting: bool)

Asks to keep self above, so that it stays on top. Note that you shouldn’t assume the window is definitely above afterward, because other entities (e.g. the user or [window manager][gtk-X11-arch]) could not keep it above, and not all window managers support keeping windows above. But normally the window will end kept above. Just don’t write code that crashes if not. Read more
Source§

fn set_keep_below(&self, setting: bool)

Asks to keep self below, so that it stays in bottom. Note that you shouldn’t assume the window is definitely below afterward, because other entities (e.g. the user or [window manager][gtk-X11-arch]) could not keep it below, and not all window managers support putting windows below.

fn set_modal(&self, modal: bool)

Sets a window modal or non-modal. Modal windows prevent interaction with other windows in the same application. To keep modal dialogs on top of main application windows, use set_transient_for() to make the dialog transient for the parent; most [window managers][gtk-X11-arch] will then disallow lowering the dialog below the parent.

fn set_startup_id(&self, startup_id: &str)

Startup notification identifiers are used by desktop environment to track application startup, to provide user feedback and other features. This function changes the corresponding property on the underlying GdkWindow. Normally, startup identifier is managed automatically and you should only use this function in special cases like transferring focus from other processes. You should use this function before calling present() or any equivalent function generating a window map event. Read more
Source§

fn set_title(&self, title: &str)

Sets the title of the Window. The title of a window will be displayed in its title bar; on the X Window System, the title bar is rendered by the [window manager][gtk-X11-arch], so exactly how the title appears to users may vary according to a user’s exact configuration. The title should help a user distinguish this window from other windows they may have open. A good title might include the application name and current document filename, for example. Read more

fn set_transient_for(&self, parent: Option<&impl IsA<Window>>)

Dialog windows should be set transient for the main application window they were spawned from. This allows [window managers][gtk-X11-arch] to e.g. keep the dialog on top of the main window, or center the dialog over the main window. gtk_dialog_new_with_buttons() and other convenience functions in GTK+ will sometimes call set_transient_for() on your behalf.

fn stick(&self)

Asks to stick self, which means that it will appear on all user desktops. Note that you shouldn’t assume the window is definitely stuck afterward, because other entities (e.g. the user or [window manager][gtk-X11-arch] could unstick it again, and some window managers do not support sticking windows. But normally the window will end up stuck. Just don’t write code that crashes if not. Read more

fn unfullscreen(&self)

Asks to toggle off the fullscreen state for self. Note that you shouldn’t assume the window is definitely not full screen afterward, because other entities (e.g. the user or [window manager][gtk-X11-arch]) could fullscreen it again, and not all window managers honor requests to unfullscreen windows. But normally the window will end up restored to its normal state. Just don’t write code that crashes if not. Read more
Source§

fn unmaximize(&self)

Asks to unmaximize self. Note that you shouldn’t assume the window is definitely unmaximized afterward, because other entities (e.g. the user or [window manager][gtk-X11-arch]) could maximize it again, and not all window managers honor requests to unmaximize. But normally the window will end up unmaximized. Just don’t write code that crashes if not. Read more

Source§

fn can_activate_accel(&self, signal_id: u32) -> bool

Determines whether an accelerator that activates the signal identified by signal_id can currently be activated. This is done by emitting the can-activate-accel signal on self; if the signal isn’t overridden by a handler or in a derived widget, then the default check is that the widget must be sensitive, and the widget and all its ancestors mapped.

Source§

fn drag_dest_add_image_targets(&self)

Add the image targets supported by SelectionData to the target list of the drag destination. The targets are added with info = 0. If you need another value, use TargetList::add_image_targets() and drag_dest_set_target_list().
Source§

fn drag_dest_add_text_targets(&self)

Add the text targets supported by SelectionData to the target list of the drag destination. The targets are added with info = 0. If you need another value, use TargetList::add_text_targets() and drag_dest_set_target_list().
Source§

fn drag_dest_add_uri_targets(&self)

Add the URI targets supported by SelectionData to the target list of the drag destination. The targets are added with info = 0. If you need another value, use TargetList::add_uri_targets() and drag_dest_set_target_list().
Source§

fn drag_dest_find_target( &self, context: &DragContext, target_list: Option<&TargetList>, ) -> Option<Atom>

Looks for a match between the supported targets of context and the dest_target_list, returning the first matching target, otherwise returning GDK_NONE. dest_target_list should usually be the return value from drag_dest_get_target_list(), but some widgets may have different valid targets for different parts of the widget; in that case, they will have to implement a drag_motion handler that passes the correct target list to this function.

fn drag_dest_unset(&self)

Clears information about a drop destination set with WidgetExtManual::drag_dest_set(). The widget will no longer receive notification of drags.
Source§

fn drag_get_data(&self, context: &DragContext, target: &Atom, time_: u32)

Gets the data associated with a drag. When the data is received or the retrieval fails, GTK+ will emit a drag-data-received signal. Failure of the retrieval is indicated by the length field of the selection_data signal parameter being negative. However, when drag_get_data() is called implicitely because the DestDefaults::DROP was set, then the widget will not receive notification of failed drops. Read more
Source§

fn drag_highlight(&self)

fn set_device_events(&self, device: &Device, events: EventMask)

Sets the device event mask (see gdk::EventMask) for a widget. The event mask determines which events a widget will receive from device. Keep in mind that different widgets have different default event masks, and by changing the event mask you may disrupt a widget’s functionality, so be careful. This function must be called while a widget is unrealized. Consider add_device_events() for widgets that are already realized, or if you want to preserve the existing event mask. This function can’t be used with windowless widgets (which return false from has_window()); to get events on those widgets, place them inside a EventBox and receive events on the event box. Read more

fn set_direction(&self, dir: TextDirection)

Sets the reading direction on a particular widget. This direction controls the primary direction for widgets containing text, and also the direction in which the children of a container are packed. The ability to set the direction is present in order so that correct localization into languages with right-to-left reading directions can be done. Generally, applications will let the default reading direction present, except for containers where the containers are arranged in an order that is explicitly visual rather than logical (such as buttons for text justification).

fn set_has_window(&self, has_window: bool)

Specifies whether self has a gdk::Window of its own. Note that all realized widgets have a non-None “window” pointer (window() never returns a None window when a widget is realized), but for many of them it’s actually the gdk::Window of one of its parent widgets. Widgets that do not create a window for themselves in realize must announce this by calling this function with has_window = false. Read more

fn connect_drag_drop<F: Fn(&Self, &DragContext, i32, i32, u32) -> bool + 'static>( &self, f: F, ) -> SignalHandlerId

The ::drag-drop signal is emitted on the drop site when the user drops the data onto the widget. The signal handler must determine whether the cursor position is in a drop zone or not. If it is not in a drop zone, it returns false and no further processing is necessary. Otherwise, the handler returns true. In this case, the handler must ensure that gtk_drag_finish() is called to let the source know that the drop is done. The call to gtk_drag_finish() can be done either directly or in a drag-data-received handler which gets triggered by calling drag_get_data() to receive the data for one or more of the supported targets.

fn intersect( &self, area: &Rectangle, intersection: Option<&mut Rectangle>, ) -> bool

Computes the intersection of a self’s area and area, storing the intersection in intersection, and returns true if there was an intersection. intersection may be None if you’re only interested in whether there was an intersection. Read more

fn connect_map_event<F: Fn(&Self, &Event) -> Propagation + 'static>( &self, f: F, ) -> SignalHandlerId

The ::map-event signal will be emitted when the widget’s window is mapped. A window is mapped when it becomes visible on the screen. Read more

fn connect_unmap_event<F: Fn(&Self, &Event) -> Propagation + 'static>( &self, f: F, ) -> SignalHandlerId

The ::unmap-event signal will be emitted when the widget’s window is unmapped. A window is unmapped when it becomes invisible on the screen. Read more

fn add_tick_callback<P: Fn(&Self, &FrameClock) -> ControlFlow + 'static>( &self, callback: P, ) -> TickCallbackId

Queues an animation frame update and adds a callback to be called before each frame. Until the tick callback is removed, it will be called frequently (usually at the frame rate of the output device or as quickly as the application can be repainted, whichever is slower). For this reason, is most suitable for handling graphics that change every frame or every few frames. The tick callback does not automatically imply a relayout or repaint. If you want a repaint or relayout, and aren’t changing widget properties that would trigger that (for example, changing the text of a Label), then you will have to call WidgetExt::queue_resize() or WidgetExt::queue_draw_area() yourself.

fn add_events(&self, events: EventMask)

Adds the events in the bitfield events to the event mask for self. See WidgetExtManual::set_events() and the [input handling overview][event-masks] for details. Read more

fn events(&self) -> EventMask

Returns the event mask (see gdk::EventMask) for the widget. These are the events that the widget will receive. Read more

fn set_events(&self, events: EventMask)

Sets the event mask (see gdk::EventMask) for a widget. The event mask determines which events a widget will receive. Keep in mind that different widgets have different default event masks, and by changing the event mask you may disrupt a widget’s functionality, so be careful. This function must be called while a widget is unrealized. Consider WidgetExtManual::add_events() for widgets that are already realized, or if you want to preserve the existing event mask. This function can’t be used with widgets that have no window. (See WidgetExt::has_window()). To get events on those widgets, place them inside a EventBox and receive events on the event box.

unsafe fn destroy(&self)

Calls gtk_widget_destroy() on this widget. Read more

fn hide_on_delete(&self) -> Propagation

Utility function; intended to be connected to the delete-event signal on a Window. The function calls WidgetExt::hide() on its argument, then returns true. If connected to ::delete-event, the result is that clicking the close button for a window (on the window frame, top right corner usually) will hide but not destroy the window. By default, GTK+ destroys windows when ::delete-event is received. Read more
