Please install Adobe's SVG-Viewer 3.0 (ASV3.0) plug-in from Adobe-site to view following SVG Components:

US Map [Please Move Mouse over the Red-squares/Dots in the Middle]

It is possible to create GUI-Classes that take any two CCG-objects and displays the first component at a given location and pops-up the second component, if mouse moves (or upon mouse click) on the first component.

For example:
LandMarkTemplete  LM_Obj1 = new LandMarkTemplete (CCG1, CCG2, loc_x, loc-y);

// Where, loc_x and loc_y gives the coordinates for the CCG1's component.
// The
CCG2 is presented upon mouse action. (Please move mouse over RED-Rectangle)
// loc_x and loc_y are usually set to ZERO, so that parent can determine the location (see below)

//The map is drawn on a "canvas" (please click here for a Canvas example):
// The following statement instantiates the Canvas's GUI-Object.
CanvasTemplate CanvasObj1 = new CanvasTemplate (x_size, y_size, width, height);

// Create the back-ground Vector map for any country (or City/State). 
MapComponentFactory MAP_Obj = new MapComponentFactory("USA", COUNTRY);

//Now, to add each component to the Canvas's Object, use its methods. For example:
CanvasObj1.addComponent ( MAP_Obj,  0,  0); 
// Add map as the background
CanvasObj1.addComponent ( LM_Obj1,  loc_x1,  loc_y1); // Add first landmark
CanvasObj1.addComponent ( LM_Obj2,  loc_x2,  loc_y2); // Add second landmark
CanvasObj1.addComponent ( LM_Obj3,  loc_x3,  loc_y3); // Repeat it to add landmarks
Note: The order is important. First component is shown at the bottom of the SVG-image stack. If we add the MAP_Obj last, all the landmark components added before will be hidden behind the Map.

The above SVG example showed three types of Landmark GUI-Classes:

  1. A pop-up information component (Auto Hide, upon mouse out).

  2. A pop-up window to show the information subcomponent.

  3. A info-component to be displayed at a specific location away from the map.

Note: In the above example, we have used simple Circle or Squire for the Land Marks, but they could be complex components, having 10 subcomponents and thousands of lines of code.

Usually the GUI-classes do not restrict the complexity of the subcomponents. There is no technical limitation that require us to restrict the complexity of the subcomponents. However, some cases the extra testing effort may not give any advantage, if user always use certain types of components.

Following are just Bitmaps. But we could modify those programs to create SVG Trees.
