Default Edit Menu

Problem

This example shows how to implement a default Edit menu into an application using GCC (it was taken of the Code Warrior examples included with the PalmOS? SDK).

This way you save code for handling these functions: Copy, Paste, Cut, Undo, Select All, Keyboard and Graffiti .

 

Solution

Define the following resource IDs. PilRC will print a warning if you don't use the --allowEditIDs command line switch:

 

// System Menu Bar and Menus
#define sysEditMenuID                 10000
#define sysEditMenuUndoCmd        10000
#define sysEditMenuCutCmd          10001
#define sysEditMenuCopyCmd        10002
#define sysEditMenuPasteCmd       10003
#define sysEditMenuSelectAllCmd   10004
#define sysEditMenuSeparator       10005
#define sysEditMenuKeyboardCmd  10006
#define sysEditMenuGraffitiCmd     10007

Then define the menu bar in your .RCP file like this (adapt to your needs):

 

// Menubars
MENU ID MainMenuBar
BEGIN
  PULLDOWN "Edit"
   BEGIN
      MENUITEM "Undo" ID sysEditMenuUndoCmd "U"
      MENUITEM "Cut" ID sysEditMenuCutCmd "X"
      MENUITEM "Copy" ID sysEditMenuCopyCmd "C"
      MENUITEM "Paste" ID sysEditMenuPasteCmd "P"
      MENUITEM "Select all" ID sysEditMenuSelectAllCmd "S"
      MENUITEM "-" sysEditMenuSeparator
      MENUITEM "Keyboard" ID sysEditMenuKeyboardCmd "K"
      MENUITEM "Grafitti" ID sysEditMenuGraffitiCmd "G"
   END

   PULLDOWN "Options"
   BEGIN
      MENUITEM "About..." ID OptionsAboutHipso
   END
END

If you only have a form with an edit menu, you can specify the menu ID 10000 in the form and get the system's built-in Edit-only menu.

Here is the menu handle function:

 

Boolean PrvHandleMenu (UInt16 menuItem) {
  Boolean result = false;
  
  switch (menuItem) {
    case OptionsAboutHipso:
      FrmPopupForm (AboutBoxAlert);
      result = true;
      break;
 
    default:
      result = false;
      break;
  }
  return result;
}

.
