The usage of this 15// container is similar to GtkFixed. 16// 17// The "child-size-request" signal is optional, if you want to expand child 18// widgets to customized size other than the container's size. It should have 19// the following signature: 20// 21// void (*child_size_request)(GtkExpandedContainer* container, 22// GtkWidget* child, 23// GtkRequisition* requisition); 24// 25// This signal is emitted for each child with the requisition set to the size of 26// the container. Your handler may adjust the value of the requisition. If the 27// width or height is set to -1, then that direction will not be expanded, and 28// the original size request of the child will be used. 29 30G_BEGIN_DECLS 31 32#define GTK_TYPE_EXPANDED_CONTAINER \ 33 (gtk_expanded_container_get_type()) 34#define GTK_EXPANDED_CONTAINER(obj) \ 35 (G_TYPE_CHECK_INSTANCE_CAST((obj), GTK_TYPE_EXPANDED_CONTAINER, \ 36 GtkExpandedContainer)) 37#define GTK_EXPANDED_CONTAINER_CLASS(klass) \ 38 (G_TYPE_CHECK_CLASS_CAST((klass), GTK_TYPE_EXPANDED_CONTAINER, \ 39 GtkExpandedContainerClass)) 40#define GTK_IS_EXPANDED_CONTAINER(obj) \ 41 (G_TYPE_CHECK_INSTANCE_TYPE((obj), GTK_TYPE_EXPANDED_CONTAINER)) 42#define GTK_IS_EXPANDED_CONTAINER_CLASS(klass) \ 43 (G_TYPE_CHECK_CLASS_TYPE((klass), GTK_TYPE_EXPANDED_CONTAINER)) 44#define GTK_EXPANDED_CONTAINER_GET_CLASS(obj) \ 45 (G_TYPE_INSTANCE_GET_CLASS((obj), GTK_TYPE_EXPANDED_CONTAINER, \ 46 GtkExpandedContainerClass)) 47 48typedef struct _GtkExpandedContainer GtkExpandedContainer; 49typedef struct _GtkExpandedContainerClass GtkExpandedContainerClass; 50 51struct _GtkExpandedContainer { 52 // Parent class. 53 GtkFixed fixed; 54}; 55 56struct _GtkExpandedContainerClass { 57 GtkFixedClass parent_class; 58}; 59 60UI_EXPORT GType gtk_expanded_container_get_type() G_GNUC_CONST; 61UI_EXPORT GtkWidget* gtk_expanded_container_new(); 62UI_EXPORT void gtk_expanded_container_put(GtkExpandedContainer* container, 63 GtkWidget* widget, gint x, gint y); 64UI_EXPORT void gtk_expanded_container_move(GtkExpandedContainer* container, 65 GtkWidget* widget, gint x, gint y); 66UI_EXPORT void gtk_expanded_container_set_has_window( 67 GtkExpandedContainer* container, 68 gboolean has_window); 69UI_EXPORT gboolean gtk_expanded_container_get_has_window( 70 GtkExpandedContainer* container); 71 72G_END_DECLS 73 74#endif // UI_BASE_GTK_GTK_EXPANDED_CONTAINER_H_ 75
