These functions are used by the routines that are responsible for building the actual widgets from the XML node data structures.
GtkWidget* (*GladeNewFunc) (GladeXML *xml, GladeWidgetInfo *info); |
This function signature should be used by functions that build particular widget types. The function should create the new widget and set any non standard widget parameters (ie. don't set visibility, size, etc), as this is handled by glade_xml_build_widget, which calls these functions.
void (*GladeBuildChildrenFunc) (GladeXML *xml, GtkWidget *w, GladeWidgetInfo *info, const char *longname); |
This function signature should be used by functions that are responsible for adding children to a container widget. To create each child widget, glade_xml_build_widget should be called.
GtkWidget* glade_xml_build_widget (GladeXML *self, GladeWidgetInfo *info, const char *parent_long); |
This function is not intended for people who just use libglade. Instead it is for people extending it (it is designed to be called in the child build routine defined for the parent widget). It first checks the type of the widget from the class tag, then calls the corresponding widget creation routine. This routine sets up all the settings specific to that type of widget. Then general widget settings are performed on the widget. Then it sets up accelerators for the widget, and extracts any signal information for the widget. Then it checks to see if there are any child widget nodes for this widget, and if so calls the widget's build routine, which will create the children with this function and add them to the widget in the appropriate way. Finally it returns the widget.
void glade_xml_set_common_params (GladeXML *self, GtkWidget *widget, GladeWidgetInfo *info, const char *parent_long); |
This function sets the common parameters on a widget, and is responsible for inserting it into the GladeXML object's internal structures. It will also add the children to this widget. Usually this function is only called by glade_xml_build_widget, but is exposed for difficult cases, such as setting up toolbar buttons and the like.
struct GladeWidgetBuildData { char *name; GladeNewFunc new; GladeBuildChildrenFunc build_children; }; |
void glade_register_widgets (const GladeWidgetBuildData *widgets); |
This function is used to register new sets of widget building functions. each member of widgets contains the widget name, a function to build a widget of that type, and optionally a function to build the children of this widget. The child building routine would call glade_xml_build_widget on each child node to create the child before packing it.
This function is mainly useful for addon widget modules for libglade (it would get called from the glade_init_module function).
gchar* glade_xml_relative_file (GladeXML *self, const gchar *filename); |
This function resolves a relative pathname, using the directory of the XML file as a base. If the pathname is absolute, then the original filename is returned.
gint glade_enum_from_string (GtkType type, const char *string); |
This helper routine is designed to be used by widget build routines to convert the string representations of enumeration values found in the XML descriptions to the integer values that can be used to configure the widget.
GtkAdjustment* glade_get_adjustment (GladeWidgetInfo *info); |
This utility routine is used to create an adjustment object for a widget.
void glade_xml_set_window_props (GtkWindow *window, GladeWidgetInfo *info); |
This is a convenience function to set some common attributes on GtkWindow widgets and widgets derived from GtkWindow. It does not set the title or the window type, as these may need special handling in some widgets.
void glade_standard_build_children (GladeXML *self, GtkWidget *w, GladeWidgetInfo *info, const char *longname); |
This is the standard child building function. It simply calls gtk_container_add on each child to add them to the parent. It is implemented here, as it should be useful to many GTK+ based widget sets.
char* glade_xml_gettext (GladeXML *xml, const char *msgid); |
This function is a wrapper for gettext, that uses the translation domain requested by the user of the function, or the default if no domain has been specified. This should be used for translatable strings in all widget building routines.
void glade_xml_set_toplevel (GladeXML *xml, GtkWindow *window); |
This is used while the tree is being built to set the toplevel window that is currently being built. It is mainly used to enable GtkAccelGroup's to be bound to the correct window, but could have other uses.
GtkAccelGroup* glade_xml_ensure_accel (GladeXML *xml); |
This function is used to get the current GtkAccelGroup. If there isn't one, a new one is created and bound to the current toplevel window (if a toplevel has been set).
void glade_xml_push_uline_accel (GladeXML *xml, GtkAccelGroup *uline); |
Push a new uline accel group onto the stack. This is intended for use by GtkMenu so that GtkMenuItem's can set up underline accelerators.
void glade_xml_handle_label_accel (GladeXML *xml, const gchar *target, guint key); |
This function is called by the GtkLabel creation routine to register an underline accelerator for the label. If the target widget exists, the accelerator is connected to the grab_focus signal. If it does not exist yet, the (target, key) pair is saved so that it can be attached when the widget is created. If target is NULL, then the accelerator should be attached to one of the parents of this widget (typically a GtkButton).
