Display Manager component
A component designed to simplify the process of drawing primitives and text onto a graphical display. Keeps track of coordinates so you don't have to. Also works great as a base layer for gLCD based games as it will check for collisions and perform movement.
Component Source Code
Please click here for the component source code: FC_Comp_Source_DisplayManager.fcfx
Detailed description
The component can create the follow objects.
Type_line - A simple straight line.
Type_Rectangle - A simple rectangular box.
Type_RectangeFilled - A filled rectangular box.
Type_Ellipse - A simple ellipse or circle.
Type_EllipseFilled - A filled ellipse or circle.
Type_TextBox - A text area allowing a line of text to be displayed.
The type can be entered by using the public constants. Begin with the Display Manager handle name followed by :: and the list of the public variables will be displayed.
For example... DisplayManager1::Type_TextBox
Examples
An example showing the creation of some text areas inside formatted shapes.
