| #define GLADE_HOOKUP_OBJECT | ( | component, | |||
| widget, | |||||
| name | ) |
g_object_set_data_full (G_OBJECT (component), name, \
gtk_widget_ref (widget), (GDestroyNotify) gtk_widget_unref)
Hookup object to widget with call to g_object_set_data_full.
Link a widget to an other widget by a specific name.
The linked widget can latter be retrieved using g_object_get_data, the current macro is in fact just a wrapper to the g_object_set_data_full GTK function.

| #define GLADE_HOOKUP_OBJECT_NO_REF | ( | component, | |||
| widget, | |||||
| name | ) | g_object_set_data (G_OBJECT (component), name, widget) |
Hookup object to widget with call to g_object_set_data.
Simpler version of the GLADE_HOOKUP_OBJECT that uses g_object_set_data instead of g_object_set_data_full.

| GtkWidget* create_window | ( | void | ) |
Create a GTK window.
This function creates a window that will contain the representation of the graph.
Definition at line 120 of file gvplugin_xgtk.cpp.
| static void gtk_finalize | ( | GVJ_t * | firstjob | ) | [static] |
End point for the plug-in engine.
This function is the end point for the gvdevice_engine_t object.
This function shows the main window and starts the gtk_main object.
| firstjob | job structure of the plug-in, and only by the way |
Definition at line 206 of file gvplugin_xgtk.cpp.
| static void gtk_initialize | ( | GVJ_t * | firstjob | ) | [static] |
Start point for the plug-in.
This function is the start point of the gvdevice_engine_t object.
Making it the start point of the render plug-in. It is responsible for starting GTK and initializing the display.
It can NOT start the gtk_main function.
| firstjob | job structure of the plug-in |
Definition at line 176 of file gvplugin_xgtk.cpp.
| GtkWidget* lookup_widget | ( | GtkWidget * | widget, | |
| const gchar * | widget_name | |||
| ) |
Obtain a widget from a lower point in the widget structure.
This function works it way up the parent of the widget until it reaches the desired widget.
This function is used in conjunction with macros GLADE_HOOKUP_OBJECT and GLADE_HOOKUP_OBJECT_NO_REF.
It will not work if the widget was not added using these macros.
| widget | the source | |
| widget_name | reference name of the widget to obtain |
Definition at line 86 of file gvplugin_xgtk.cpp.
| gboolean Redraw | ( | gpointer | data | ) |
Redraw main window.
This function invalidates the main window which makes it redraw itself, this is a way to periodically call the expose event.
| data | input data pointer, the window widget to invalidate is received here |
