- ' You can stop GuiDesigner from putting the following comment
- ' lines in callback functions by removing the comment lines in
- ' the code.xxx file in your \xb\xxx directory.
- '
- ' This is a callback function that supports the grid function
- ' of the same name less the last 4 letters (Code).
- '
- ' When an important event occurs in the grid function created
- ' from your design window, is sends a callback message to this
- ' function, with the original message in r1.
- '
- ' Most callback functions process only Selection messages
- ' because usually that's enough to perform their function.
- '
- ' When keystrokes are entered into a TextLine or TextArea grid,
- ' this callback function receives a TextEvent callback message.
- ' This function can prevent Keystrokes from inserting characters
- ' in the TextLine or TextArea grid by returning a -1 in kid.
- '
- ' The first time GuiDesigner generates this function, it puts
- ' a "SUB Selection" subroutine at the bottom of the function.
- ' It contains a SELECT CASE block with kid constants named the
- ' same as the grids you put in the design window. For grids
- ' you didn't give a name (with the AppearanceWindow), a not
- ' very useful default name is substituted, so be sure to enter
- ' good GridNames in the Appearance window for every grid in
- ' your design windows. If you change the GridNames later, the
- ' names in the SELECT CASE block are NOT updated, and you'll
- ' get "Undefined Constant" errors on lines with obsolete constant
- ' names when you recompile the program. Then you'll have to
- ' update the names in the SELECT CASE block by hand.
- '
- ' It's easy to find out what your code has to respond to...
- ' just run your program! When you operate the grids in the
- ' window, the XuiReportMessage() call in this function prints
- ' the entry arguments in a ReportMessage window. You can
- ' comment out this lines to disable this feature, but don't
- ' remove them entirely - it might come in handy later.
