Libglade BuildSynopsis
DescriptionThese functions are used by the routines that are responsible for building the actual widgets from the XML node data structures. DetailsGladeNewFunc ()
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. GladeBuildChildrenFunc ()
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. glade_xml_build_widget ()
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. glade_xml_set_common_params ()
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
glade_register_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). glade_xml_relative_file ()
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. glade_enum_from_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. glade_get_adjustment ()
This utility routine is used to create an adjustment object for a widget. glade_xml_set_window_props ()
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. glade_standard_build_children ()
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. glade_xml_gettext ()
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. glade_xml_set_toplevel ()
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. glade_xml_ensure_accel ()
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). glade_xml_push_uline_accel ()
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. glade_xml_pop_uline_accel ()
Pops the uline accel group. This will usually be called after a GtkMenu has built all its children. glade_xml_get_uline_accel ()
This function is intended for use in menu items when setting up underline accelerators. glade_xml_handle_label_accel ()
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). glade_xml_get_parent_accel ()
This function gets the latest label underline accelerator directed at the parent widget. If there is no accelerator waiting, 0 is returned. If this function is called twice in a row, the second call will always return 0. |
