* SECTION:gtkwindow
|
||
* @title: GtkWindow
|
||
* @short_description: Toplevel which can contain other widgets
|
||
*
|
||
* A GtkWindow is a toplevel window which can contain other widgets.
|
||
* Windows normally have decorations that are under the control
|
||
* of the windowing system and allow the user to manipulate the window
|
||
* (resize it, move it, close it,...).
|
||
*
|
||
* # GtkWindow as GtkBuildable
|
||
*
|
||
* The GtkWindow implementation of the GtkBuildable interface supports a
|
||
* custom <accel-groups> element, which supports any number of <group>
|
||
* elements representing the #GtkAccelGroup objects you want to add to
|
||
* your window (synonymous with gtk_window_add_accel_group().
|
||
*
|
||
* An example of a UI definition fragment with accel groups:
|
||
* |[
|
||
* <object class="GtkWindow">
|
||
* <accel-groups>
|
||
* <group name="accelgroup1"/>
|
||
* </accel-groups>
|
||
* </object>
|
||
*
|
||
* ...
|
||
*
|
||
* <object class="GtkAccelGroup" id="accelgroup1"/>
|
||
* ]|
|
||
*
|
||
* The GtkWindow implementation of the GtkBuildable interface supports
|
||
* setting a child as the titlebar by specifying “titlebar” as the “type”
|
||
* attribute of a <child> element.
|
||
*
|
||
* # CSS nodes
|
||
*
|
||
* |[<!-- language="plain" -->
|
||
* window.background
|
||
* ├── decoration
|
||
* ├── <titlebar child>.titlebar [.default-decoration]
|
||
* ╰── <child>
|
||
* ]|
|
||
*
|
||
* GtkWindow has a main CSS node with name window and style class .background,
|
||
* and a subnode with name decoration.
|
||
*
|
||
* Style classes that are typically used with the main CSS node are .csd (when
|
||
* client-side decorations are in use), .solid-csd (for client-side decorations
|
||
* without invisible borders), .ssd (used by mutter when rendering server-side
|
||
* decorations). GtkWindow also represents window states with the following
|
||
* style classes on the main node: .tiled, .maximized, .fullscreen. Specialized
|
||
* types of window often add their own discriminating style classes, such as
|
||
* .popup or .tooltip.
|
||
*
|
||
* GtkWindow adds the .titlebar and .default-decoration style classes to the
|
||
* widget that is added as a titlebar child.

|
||
* In GTK+, #GTK_WINDOW_POPUP means a pop-up menu or pop-up tooltip.
|

* On X11, popup windows are not controlled by the

* [window manager][gtk-X11-arch].
|

*
|
||
* All top-level windows created by gtk_window_new() are stored in
|
||
* an internal top-level window list. This list can be obtained from
|
||
* gtk_window_list_toplevels(). Due to Gtk+ keeping a reference to

||
* the window internally, gtk_window_new() does not return a reference

|
||
*
|

* The default size of a window only affects the first time a window is

* shown; if a window is hidden and re-shown, it will remember the size
|
||
* it had prior to hiding, rather than using the default size.
|
||
*
|
||
* Windows can’t actually be 0x0 in size, they must be at least 1x1, but
|
||
* passing 0 for @width and @height is OK, resulting in a 1x1 default size.

*
|

|
||
*
|
||
* If you are getting a window size in order to position the window

* on the screen, you should, instead, simply set the window’s semantic

* If the configure request has not changed, we don't ever resend

* it, because it could mean fighting the user or window manager.
|

*
|

* - the one from gtk_window_move()/gtk_window_resize()

/* Position Constraints
|
||
* ====================
|
||
*
|
||
* POS_CENTER_ALWAYS is conceptually a constraint rather than
|
||
* a default. The other POS_ values are used only when the
|
||
* window is shown, not after that.
|
||
*
|
||
* However, we can't implement a position constraint as
|
||
* "anytime the window size changes, center the window"
|
||
* because this may well end up fighting the WM or user. In
|
||
* fact it gets in an infinite loop with at least one WM.
|
||
*
|
||
* Basically, applications are in no way in a position to
|
||
* constrain the position of a window, with one exception:
|
||
* override redirect windows. (Really the intended purpose
|
||
* of CENTER_ALWAYS anyhow, I would think.)
|
||
*
|
||
* So the way we implement this "constraint" is to say that when WE
|
||
* cause a move or resize, i.e. we make a configure request changing
|
||
* window size, we recompute the CENTER_ALWAYS position to reflect
|
||
* the new window size, and include it in our request. Also, if we
|
||
* just turned on CENTER_ALWAYS we snap to center with a new
|
||
* request. Otherwise, if we are just NOTIFIED of a move or resize
|
||
* done by someone else e.g. the window manager, we do NOT send a
|
||
* new configure request.
|
||
*
|
||
* For override redirect windows, this works fine; all window
|
||
* sizes are from our configure requests. For managed windows,
|
||
* it is at least semi-sane, though who knows what the
|
||
* app author is thinking.
|
||
*/
|
||
|
||
/* This condition should be kept in sync with the condition later on

||
* that determines whether we send a configure request. i.e. we
