| michael@0 | 18 | * MozContainer |
| michael@0 | 19 | * |
| michael@0 | 20 | * This class serves two purposes in the nsIWidget implementation. |
| michael@0 | 21 | * |
| michael@0 | 22 | * - It provides objects to receive signals from GTK for events on native |
| michael@0 | 23 | * windows. |
| michael@0 | 24 | * |
| michael@0 | 25 | * - It provides a container parent for GtkWidgets. The only GtkWidgets |
| michael@0 | 26 | * that need this in Mozilla are the GtkSockets for windowed plugins (Xt |
| michael@0 | 27 | * and XEmbed). |
| michael@0 | 28 | * |
| michael@0 | 29 | * Note that the window hierarchy in Mozilla differs from conventional |
| michael@0 | 30 | * GtkWidget hierarchies. |
| michael@0 | 31 | * |
| michael@0 | 32 | * Mozilla's hierarchy exists through the GdkWindow hierarchy, and all child |
| michael@0 | 33 | * GdkWindows (within a child nsIWidget hierarchy) belong to one MozContainer |
| michael@0 | 34 | * GtkWidget. If the MozContainer is unrealized or its GdkWindows are |
| michael@0 | 35 | * destroyed for some other reason, then the hierarchy no longer exists. (In |
| michael@0 | 36 | * conventional GTK clients, the hierarchy is recorded by the GtkWidgets, and |
| michael@0 | 37 | * so can be re-established after destruction of the GdkWindows.) |
| michael@0 | 38 | * |
| michael@0 | 39 | * One consequence of this is that the MozContainer does not know which of its |
| michael@0 | 40 | * GdkWindows should parent child GtkWidgets. (Conventional GtkContainers |
| michael@0 | 41 | * determine which GdkWindow to assign child GtkWidgets.) |
| michael@0 | 42 | * |
| michael@0 | 43 | * Therefore, when adding a child GtkWidget to a MozContainer, |
| michael@0 | 44 | * gtk_widget_set_parent_window should be called on the child GtkWidget before |
| michael@0 | 45 | * it is realized. |
