Brushes

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
