|
|
* MozContainer
|
|
*
|
|
* This class serves two purposes in the nsIWidget implementation.
|
|
*
|
|
* - It provides objects to receive signals from GTK for events on native
|
|
* windows.
|
|
*
|
|
* - It provides a container parent for GtkWidgets. The only GtkWidgets
|
|
* that need this in Mozilla are the GtkSockets for windowed plugins (Xt
|
|
* and XEmbed).
|
|
*
|
|
* Note that the window hierarchy in Mozilla differs from conventional
|
|
* GtkWidget hierarchies.
|
|
*
|
|
* Mozilla's hierarchy exists through the GdkWindow hierarchy, and all child
|
|
* GdkWindows (within a child nsIWidget hierarchy) belong to one MozContainer
|
|
* GtkWidget. If the MozContainer is unrealized or its GdkWindows are
|
|
* destroyed for some other reason, then the hierarchy no longer exists. (In
|
|
* conventional GTK clients, the hierarchy is recorded by the GtkWidgets, and
|
|
* so can be re-established after destruction of the GdkWindows.)
|
|
*
|
|
* One consequence of this is that the MozContainer does not know which of its
|
|
* GdkWindows should parent child GtkWidgets. (Conventional GtkContainers
|
|
* determine which GdkWindow to assign child GtkWidgets.)
|
|
*
|
|
* Therefore, when adding a child GtkWidget to a MozContainer,
|
|
* gtk_widget_set_parent_window should be called on the child GtkWidget before
|
|
* it is realized.
