<p>Creates a new GtkWindow, which is a toplevel window that can contain other widgets. Nearly always, the type of the window should be GTK_WINDOW_TOPLEVEL. If you're implementing something like a popup menu from scratch (which is a bad idea, just use GtkMenu), you might use GTK_WINDOW_POPUP. GTK_WINDOW_POPUP is not for dialogs, though in some other toolkits dialogs are called "popups". 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. </p>
<p>If you simply want an undecorated window (no window borders), use gtk_window_set_decorated(), don't use GTK_WINDOW_POPUP. </p>

<p>This function returns the position you need to pass to gtk_window_move() to keep window in its current position. This means that the meaning of the returned value varies with window gravity. See gtk_window_move() for more details. </p>
<p>If you haven't changed the window gravity, its gravity will be GDK_GRAVITY_NORTH_WEST. This means that gtk_window_get_position() gets the position of the top-left corner of the window manager frame for the window. gtk_window_move() sets the position of this same top-left corner. </p>
<p>gtk_window_get_position() is not 100% reliable because the X Window System does not specify a way to obtain the geometry of the decorations placed on a window by the window manager. Thus GTK+ is using a "best guess" that works with most window managers. </p>
<p>Moreover, nearly all window managers are historically broken with respect to their handling of window gravity. So moving a window to its current position as returned by gtk_window_get_position() tends to result in moving the window slightly. Window managers are slowly getting better over time. </p>
<p>If a window has gravity GDK_GRAVITY_STATIC the window manager frame is not relevant, and thus gtk_window_get_position() will always produce accurate results. However you can't use static gravity to do things like place a window in a corner of the screen, because static gravity ignores the window manager decorations. </p>
<p>If you are saving and restoring your application's window positions, you should know that it's impossible for applications to do this without getting it somewhat wrong because applications do not have sufficient knowledge of window manager state. The Correct Mechanism is to support the session management protocol (see the "GnomeClient" object in the GNOME libraries for example) and allow the window manager to save your window sizes and positions. </p>

<p>If window is not onscreen, it returns the size GTK+ will suggest to the window manager for the initial window size (but this is not reliably the same as the size the window manager will actually select). The size obtained by gtk_window_get_size() is the last size received in a GdkEventConfigure, that is, GTK+ uses its locally-stored size, rather than querying the X server for the size. As a result, if you call gtk_window_resize() then immediately call gtk_window_get_size(), the size won't have taken effect yet. After the window manager processes the resize request, GTK+ receives notification that the size has changed via a configure event, and the size of the window gets updated. </p>
<p>Note 1: Nearly any use of this function creates a race condition, because the size of the window may change between the time that you get the size and the time that you perform some action assuming that size is the current size. To avoid race conditions, connect to "configure-event" on the window and adjust your size-dependent state to match the size delivered in the GdkEventConfigure. </p>
<p>Note 2: The returned size does not include the size of the window manager decorations (aka the window frame or border). Those are not drawn by GTK+ and GTK+ has no reliable method of determining their size. </p>
<p>Note 3: If you are getting a window size in order to position the window onscreen, there may be a better way. The preferred way is to simply set the window's semantic type with gtk_window_set_type_hint(), which allows the window manager to e.g. center dialogs. Also, if you set the transient parent of dialogs with gtk_window_set_transient_for() window managers will often center the dialog over its parent window. It's much preferred to let the window manager handle these things rather than doing it yourself, because all apps will behave consistently and according to user prefs if the window manager handles it. Also, the window manager can take the size of the window decorations/border into account, while your application cannot. </p>
<p>In any case, if you insist on application-specified window positioning, there's still a better way than doing it yourself - gtk_window_set_position() will frequently handle the details for you. </p>

<p>Asks the window manager to move window 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. </p>
<p>Note: the position is the position of the gravity-determined reference point for the window. The gravity determines two things: first, the location of the reference point in root window coordinates; and second, which point on the window is positioned at the reference point. </p>
<p>By default the gravity is GDK_GRAVITY_NORTH_WEST, so the reference point is simply the x, y supplied to gtk_window_move(). The top-left corner of the window decorations (aka window frame or border) will be placed at x, y. Therefore, to position a window at the top left of the screen, you want to use the default gravity (which is GDK_GRAVITY_NORTH_WEST) and move the window to 0,0. </p>
<p>To position a window at the bottom right corner of the screen, you would set GDK_GRAVITY_SOUTH_EAST, which means that the reference point is at x + the window width and y + the window height, and the bottom-right corner of the window border will be placed at that reference point. So, to place a window in the bottom right corner you would first set gravity to south east, then write: gtk_window_move (window, gdk_screen_width() - window_width, gdk_screen_height() - window_height) (note that this example does not take multi-head scenarios into account). </p>

<p>If gtk_window_parse_geometry() returns TRUE, it will also set the GDK_HINT_USER_POS and/or GDK_HINT_USER_SIZE hints indicating to the window manager that the size/position of the window was user-specified. This causes most window managers to honor the geometry. </p>
<p>Note that for gtk_window_parse_geometry() to work as expected, it has to be called when the window has its "final" size, i.e. after calling gtk_widget_show_all() on the contents and gtk_window_set_geometry_hints() on the window. </p>

<p>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. </p>
<p>Unlike set_size_request(), which sets a size request for a widget and thus would keep users from shrinking the window, this function only sets the initial size, just as if the user had resized the window themselves. Users can still shrink the window again as they normally would. Setting a default size of -1 means to use the "natural" default size (the size request of the window). </p>
<p>For more control over a window's initial size and how resizing works, investigate set_geometry_hints(). </p>
<p>For some uses, resize() is a more appropriate function. resize() changes the current size of the window, rather than the size to be used on initial display. resize() always affects the window itself, not the geometry widget. </p>
<p>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. </p>
<p>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. </p>

<pre class="prototype">GtkWindow.set_modal()</pre>
<p>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 will then disallow lowering the dialog below the parent. </p>

<p>Request the windowing system to make window partially transparent, with opacity 0 being fully transparent and 1 fully opaque. (Values of the opacity parameter are clamped to the [0,1] range.) On X11 this has any effect only on X screens with a compositing manager running. See gtk_widget_is_composited(). On Windows it should work always. </p>
<p>Note that setting a window's opacity after the window has been shown causes it to flicker once on Windows. </p>

</table>
<p>This function is only useful on X11, not with other GTK+ targets. </p>
<p>In combination with the window title, the window role allows a window manager to identify "the same" window when an application is restarted. So for example you might set the "toolbox" role on your app's toolbox window, so that when the user restarts their session, the window manager can put the toolbox back in the same place. </p>
<p>If a window already has a unique title, you don't need to set the role, since the WM can use the title to identify the window when restoring the session. </p>

<p>Windows may set a hint asking the desktop environment not to display the window in the pager. This function sets this hint. (A "pager" is any desktop navigation tool such as a workspace switcher that displays a thumbnail representation of the windows on the screen.) </p>

<p>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. </p>
<p>This function is only useful on X11, not with other GTK+ targets. </p>
<h3><a name="set_title">set_title</a></h3><p class="brief">Sets the title of the GtkWindow. </p>

<table class="prototype">

</tbody>
</table>
<p>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, 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. </p>
<h3><a name="set_transient_for">set_transient_for</a></h3><p class="brief">Sets the window transient for a parent window. </p>

</tbody>
</table>
<p>Dialog windows should be set transient for the main application window they were spawned from. This allows window managers 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 gtk_window_set_transient_for() on your behalf. </p>
<p>Passing NULL for parent unsets the current transient window. </p>
<p>On Windows, this function puts the child window on top of the parent, much as the window manager would have done on X. </p>

</tbody>
</table>
<p>By setting the type hint for the window, you allow the window manager to decorate and handle the window in a way which is suitable to the function of the window in your application. </p>
<p>This function should be called before the window becomes visible. </p>
<h3><a name="set_urgency_hint">set_urgency_hint</a></h3><p class="brief">Sets the window urgency hint. </p>

</table>
<p>It sets the X Window System "class" and "name" hints for a window. According to the ICCCM, you should always set these to the same value for all windows in an application, and GTK+ sets them to that value by default, so calling this function is sort of pointless. However, you may want to call gtk_window_set_role() on each window in your application, for the benefit of the session manager. Setting the role allows the window manager to restore window positions when loading a saved session. </p>
