1. Description

• In this lab we merge the code from

  • Lab 10, which implements custom drawing in CDrawBox, and

  • Lab 13, which demonstrates the use of the radio buttons and the check box widget:

   

   

2. Copying Visual Studio Project

• We will use Lab 10 project as a prototype for this exercise. Make a copy of Lab 10 subfolder

  
      c255labs\labs\c255_lab10_mouse
  
  

  or download and unzip c255_lab10_mouse.zip

• Rename the new folder as c255_lab14_draw_box.

• Open solution file in Visual Studio and finish the usual steps to rename the project.

   

3. Adding widgets in FLUID

• Start FLUID program and open Lab 13 project

  
      c255labs\labs\c255_lab13_check_box\fluid_project\CFluidWindow.fl
  
  

• Using FLUID tree view, select group of the radio buttons and the check box widget. Click menu

  
      Edit/Copy
  
  

  to copy the widgets to the operating system's clipboard.

• Open Lab 14 FLUID project

  
      c255labs\labs\c255_lab14_draw_box\fluid_project\CFluidWindow.fl
  
  

• Resize the window to make it a little bigger.

• Select Window win_app object in FLUID tree view. Use menu

  
      Edit/Paste
  
  

  to paste the widgets and re-position them as necessary.

• Save FLUID project and generate C++ code by

  
      File/Write Code...
  
  

   

4. Adding code to support the check box

• Open solution

  
      c255labs\labs\c255_lab14_draw_box\c255_lab14.sln
  
  

  in Visual Studio.

• Compile and test the program.

• Clean the solution by

  
      Build -> Clean Solution
      File -> Close Solution
  
  

• Exit Visual Studio

• Run clean_before_submit.bat in c255labs\labs\c255_lab14_draw_box. It deletes the hidden .vs subdirectory from the new project. Removing .vs saves megabytes of space on your hard drive.

   

5. Copying callback code from Lab 13 with WinMerge

• Use WinMerge to compare Lab 13 and Lab 14 folders. Use WinMerge menu

  
      File -> Open
  
  

• Specify locations of the two folders, for example,

  
      C:\BCC\c255labs\labs\c255_lab13_check_box
      C:\BCC\c255labs\labs\c255_lab14_draw_box
  
  

   

  Click OK.

• Double-click CMainWindow.h in WinMerge comparison view. The two files appear compared side-by-side with the differences highlighted.

• Right-click every highlighted item and use context-sensitive menu to copy the code over from Lab 13 to Lab 14.

• Save the changes by pressing CTRL+S or use File/Save WinMerge menu. Close the side-by-side view of CMainWindow.h.

• Repeat the same steps for CMainWindow.cpp. Double-click the file and use side-by-side view to merge the differences.

• Save the file when done and exit WinMerge.

   

6. Testing the results

• Reopen solution

  
      c255labs\labs\c255_lab14_draw_box\c255_lab14.sln
  
  

  in Visual Studio.

• Compile and test the program.

• At this stage, the radio buttons and the check box don't do much except printing debug messages on the console window. However, all required callbacks are now in place, so we are ready to implement the logic for drawing alternative shapes in the next lab.

   

7. How to submit

• This is a self-learning lab. There are no files to submit. Make sure to complete all required steps to build and test the project on your own home computer.
