#Openoffice for window windows#

Windows adds arbitrary properties to an HWND. The bean deals with this issue by adding another function to the local library. The VCL's implementation is system dependent. The parent window can be filled 'full size' with the child window, but only for UNIX and not for Windows. The VCL, Apache OpenOffice's windowing engine creates a special system child window, thus we can resize windows. The child does not resize it window, because it must know the layout of the parent window.

Normally, the child window expects resize events of the parent. If it does not work, try the hack.Īnother difficulty is resizing the window. If in doubt, implement both and try the new method at runtime. The old method still works and can be used, but it should be considered deprecated. Newer versions do not check this parameter, thus this new, method works. This method cannot be used in Apache OpenOffice build versions before src642, because the process ID parameter is unknown to the Java environment. This accepts an any with a wrapped HWND or X Window ID, as long and the system type, such as Windows, Java, and UNIX directly. The .Toolkit service implements the interface .XSystemChildFactory with a method createSystemChild(). SYSTEMDEPENDENT // now the toolkit can create an .XWindowĬom. Rectangle ( 0, 0, 0, 0 ) if (aParentView. WindowServiceName = 'workwindow' ĪDescriptor. New JavaWindowPeerFake (aParentView ) ) Ĭom. setVisible ( true ) // now wrap the canvas (JavaWindowPeerFake) and add the necessary interfacesĬom. some JNI methods cannot work before thisĪParentView. createInstance ( '.Toolkit' ) ) // this is the canvas object with the JNI methods The two methods getNativeWindow() and getNativeWindowSystemType() are declared and exported, but implemented for windows in bean/native/win32/com_sun_star_beans_LocalOfficeWindow.c through JNIĬom.

a method to identify the operating system, for example, UNIX, Windows, or Macintoshįor an example, see bean/com/sun/star/beans/LocalOfficeWindow.java.

a method to query the window handle (HWND on Windows, X11 ID on UNIX).

For this, use a and the following JNI methods: Some of this information may be helpful with other local window integrations.Īn important precondition is the existence of a system window handle of the own Java window.

This chapter shows the integration of Apache OpenOffice windows into a Java bean environment. There are multiple possibilities to integrate local windows with Apache OpenOffice windows.

The following provides background information about possible strategies to reach this goal. Usually, developers use the OfficeBean for this purpose. This section discusses experiences obtained during the development of Java-Apache OpenOffice integration.
