Package OpenCAGE.GUI.Display_Controllers.Graph_Display_Controllers

Class `GDC_Clicked_Object`

This is an Enumeration. Possible values: Background, Object, None.

Class `Graph_Display_Controller`

extends OpenCAGE.GUI.Display_Controllers.Display_Controller

Attributes

private Gdk.Types.Gdk_Key_Type Key: holds the name of the key which is pressed
private OpenCAGE.GUI.Displays.Graph_Window_Models.Graph_Window_Model Model: holds the pointer to the object of the class Window_Model
private OpenCAGE.GUI.Displays.Graph_Window_Displays.Graph_Window_Display Display: holds the pointer to the object of the class Window_Display
private OpenCAGE.GUI.Display_Controllers.Graph_Display_Controllers.GDC_Clicked_Object Last_Left_Clicked_Object: the last left clicked object (category).
private Boolean Button_Pressed: true if there was a Button_Press_Event and no Button_Release_Event
private OpenCAGE.GUI.Menus.Con_Men_Controllers.Con_Men_Controller Con_Men_Controller
private OpenCAGE.GUI.Cursors.Cursor_State_Model_Observer Cursor_Observer: This observer changes the cursor in the window according to the observed state.
private OpenCAGE.GUI.Display_Controllers.Graph_Display_Controllers.Node_Model_Observer My_Node_Model_Observer: This observer handles changes in the node model.
private OpenCAGE.GUI.Display_Controllers.Graph_Display_Controllers.Display_Observer My_Display_Observer: This observer handles changes in the displays.
private Boolean Dirty: This is set to true when the display has to be redrawn (e.g. by observers). The display controller checks this flag, when the command pipe has executed a command - notified by a milestone observer - and redraws itself if dirty.
private OpenCAGE.GUI.Display_Controllers.Graph_Display_Controllers.GDC_Milestone_Observer After_Execute_Milestone_Observer: Observer that observes the after execute pipe segment.

Operations

public Update_All(void);
public Show_Window(void);: Shows the window of the display. [This description is adopted from 'OpenCAGE.GUI.Display_Controllers.Display_Controller'.]
public Hide_Window(void);: Hides the window of the display. [This description is adopted from 'OpenCAGE.GUI.Display_Controllers.Display_Controller'.]
public Connect_Handlers(void);
public Boolean Is_Visible(void);: Returns true, if the window is visible, false otherwise. [This description is adopted from 'OpenCAGE.GUI.Display_Controllers.Display_Controller'.]
public Toggle_Visibility(void);: Shows the window, if it is hidden, hides it, else. [This description is adopted from 'OpenCAGE.GUI.Display_Controllers.Display_Controller'.]
private Add_Misc_Data( FET.Parameter_Pot Pot);: Adds some misc data only the controller knows to the given pot.
private Child_Node_Added( OpenCAGE.GIF.Node_Model Model);: Called by a model observer when received the corresponding message.
private Child_Node_Removed( OpenCAGE.GIF.Node_Model Model);: Called by a model observer when received the corresponding message.
public Raise_Window(void);: Bring window of the display to front. [This description is adopted from 'OpenCAGE.GUI.Display_Controllers.Display_Controller'.]
public OpenCAGE.GUI.Displays.Window_Displays.Window_Display Get_Display(void);: returns the display that is controlled [This description is adopted from 'OpenCAGE.GUI.Display_Controllers.Display_Controller'.]
public OpenCAGE.GUI.Displays.Window_Models.Window_Model Get_Model(void);: returns the model that is displayed by the display of this controller [This description is adopted from 'OpenCAGE.GUI.Display_Controllers.Display_Controller'.]
private Destroy_Really(void);: The controller can not be destroyed by itself, because it is destroyed by the window. So Destroy calls the destroy method of the window, the window calls an event handler that calls this method.
private Node_Display_Destroying( OpenCAGE.GUI.Displays.Node_Displays.Node_Display Node);: Called by a display observer when received the corresponding message.
private Edge_Display_Destroying( OpenCAGE.GUI.Displays.Edge_Displays.Edge_Display Edge);: Called by a display observer when received the corresponding message.
private Boolean Is_My_Background_Equal_To( OpenCAGE.GIF.Node_Model Node);: true: if the background of the graph_display_controller equals the given node. false: if not.
public Add_Incoming_Edge( OpenCAGE.GIF.Node_Model Node, OpenCAGE.GIF.Edge_Model New_Edge);: Adds an incoming edge to the given node.
public Add_Outgoing_Edge( OpenCAGE.GIF.Node_Model Node, OpenCAGE.GIF.Edge_Model New_Edge);: Adds an outgoing edge to the given node.
public Remove_Incoming_Edge( OpenCAGE.GIF.Node_Model Node, OpenCAGE.GIF.Edge_Model Old_Edge);: Remove an incoming edge from the given node.
public Remove_Outgoing_Edge( OpenCAGE.GIF.Node_Model Node, OpenCAGE.GIF.Edge_Model Old_Edge);: Remove an outgoing edge from the given node.
private Changed(void);: Called by a model observer when received the corresponding message.
public Redraw_If_Dirty(void);: Redraws the display if Dirty is True.
public Set_Oc_Data( OpenCAGE.Data.Data To);: needed to initialize further objects that need Oc_Data
