/**
|
|
A Linux-specific class that can embed a foreign X11 widget.
|
|
|
|
Use this class to embed a foreign X11 widget from other toolkits such as
|
|
GTK+ or QT.
|
|
|
|
There are two ways to initiate the Xembed protocol. Either the client creates
|
|
a window and passes this to the host (client initiated) or the host
|
|
creates a window in which the client can reparent it's client widget
|
|
(host initiated). XEmbedComponent supports both protocol types.
|
|
|
|
This is how you embed a GTK+ widget: if you are using the client
|
|
initiated version of the protocol, then create a new gtk widget with
|
|
gtk_plug_new (0). Then query the window id of the plug via gtk_plug_get_id().
|
|
Pass this id to the constructor of this class.
|
|
|
|
If you are using the host initiated version of the protocol, then first create
|
|
the XEmbedComponent using the default constructor. Use getHostWindowID to get
|
|
the window id of the host, use this to construct your gtk plug via gtk_plug_new.
|
|
|
|
A similar approach can be used to embed QT widgets via QT's QX11EmbedWidget
|
|
class.
|
|
|
|
Other toolkits or raw X11 widgets should follow the X11 embed protocol:
|
|
