Compiling
To compile the example:
- Launch EiffelStudio.
- Click Add project
- Browse to $ISE_EIFFEL\examples\wel\brushes\.
- Choose brushes.ecf
- Choose the location where the project will be compiled, by default the same directory containing the configuration file.
- Click OK.
Running
After launching the program you will see a window displayed containing three push buttons marked "Brushes", "Rectangles" and "3D". Clicking "Brushes" will open a new window demonstrating different brushes available. Clicking "Rectangles" will open a new window within which many different shaped and colored rectangles will be drawn. Clicking"3D" will open a new window demonstrating the use of multiple bitmaps for animation.
Under the Hood
Each of the three windows that are opened from the programs
MAIN_WINDOW inherit
WEL_FRAME_WINDOW and contains code for generating their output.
BRUSHES_DEMO redefines
idle_action to force a re-draw on the applicable windows.
Note. If enable_idle_action is not called, then
idle_action is never executed.
This sample contains the following classes:
- APPLICATION_IDS
- BRUSH_DEMO
- BRUSHES_DEMO
- DEMO_3D
- MAIN_WINDOW
- PROJECTION
- RECTANGLE_DEMO
