- .TUTORIAL - Using the [ DIALOG ] and [ HINT ] keywords
-
- It's time to flesh out the editor a bit. Let's add the standard
- Search & Replace dialogs.
-
- The Dialog Editor is a screen painter. You can open a file by
- pressing F3 and adding the ".DLG" file extension. Or use the menu
- command, "RUN|Dialog Editor" or (Alt-D).
-
- This lets you interactively compose dialogs to be used with the
- application. The [ DIALOG ] keyword signals SHAZAM to generate
- dialogs (*.DLG) as code (*.SRC) or resources (*.REZ).
-
- You can determine code or resources by using the SETUP|Code dialog,
- command-line switches, the [ SWITCH ] keyword or the [ DIALOG ] local
- override switch.
-
- The dialogs used in this example and the library (..\DLG) were
- created with the Dialog Editor, and have hcXX symbols assigned.
- These symbols provide a "link" to Hint Text and Help Text.
-
- *** IMPORTANT ***
- [X] When resources are used, the VALUE of an hcXX symbol is written
- to the resource file (*.REZ).
-
- [X] When code is generated, the TEXT for the hcXX symbol is written
- to the source-code file (*.SRC).
-
- When hand-coding, you MUST be aware of this! A program and its
- resources can get "out of sync", such as after you edit & compile
- help text. It can happen to cmXX values too, if you change them.
-
- During the generate process, SHAZAM ensures updated values. If you
- use the Dialog Editor to write a dialog to a resource file, load the
- Help Symbol file and use "EDIT|Help context|Update all".
-
- *****************
-
- In a definition, MenuBar and MenuBox elements have hint text on the
- same line as the SubMenu or Item, using the double semi-colon. To
- create hints for other views, use the [ HINT ] keyword to name the
- hcXX symbol and add text after a double semi-colon.
-
- Note that the hints use a naming convention, the result of which
- causes the hcXX symbols to be sorted and assigned a value in sort
- order. This allows for how TCLUSTER assigns "HelpCtx" values; ie:
- The initial value is incremented by one for each additional element
- after the first (the only element using the directly assigned
- value). See CLUSTER.DEF for a dedicated example of hints & TClusters.
-
- Corresponding Help text is covered in the next example.
