<hr><a name="_details"></a><h2>Detailed Description</h2>
A GdkDisplay C++ wrapper class.
<p>
The purpose of <a class="el" href="classGFC_1_1Gdk_1_1Display.html">Display</a> objects are two fold:<ul>
<li>To grab/ungrab the keyboard focus and mouse pointer.</li><li>To manage and provide information about the Screen(s) available for this <a class="el" href="classGFC_1_1Gdk_1_1Display.html">Display</a>.</li></ul>
<p>
<a class="el" href="classGFC_1_1Gdk_1_1Display.html">Display</a> objects are the GDK representation of the X <a class="el" href="classGFC_1_1Gdk_1_1Display.html">Display</a> which can be described as a workstation consisting of a keyboard, a pointing device (such as a mouse) and one or more screens. It is used to open and keep track of various <a class="el" href="classGFC_1_1Gdk_1_1Screen.html">Screen</a> objects currently instantiated by the application. It is also used to grab and release the keyboard and mouse pointer.

Flushes any requests queued for the windowing system.
<p>
This happens automatically when the main loop blocks waiting for new events, but if your application is drawing without returning control to the main loop, you may need to call this function explicitely. A common case where this function needs to be called is when an application is executing drawing commands from a thread other than the thread where the main loop is running.<p>
This method is most useful for X11. On windowing systems where requests are handled synchronously, this method will do nothing. </td>

Flushes any requests queued for the windowing system and waits until all requests have been handled.

This is often used for making sure that the display is synchronized with the current state of the program. Calling <a class="el" href="classGFC_1_1Gdk_1_1Display.html#z116_3">sync()</a> before gdk_error_trap_pop() makes sure that any errors generated from earlier requests are handled before the error trap is removed. This is most useful for X11. On windowing systems where requests are handled synchronously, this function will do nothing. </td>
