- @page overview_tips wxTipProvider overview
-
- Many "modern" Windows programs have a feature (some would say annoyance) of
- presenting the user tips at program startup. While this is probably useless to
- the advanced users of the program, the experience shows that the tips may be
- quite helpful for the novices and so more and more programs now do this.
- For a wxWidgets programmer, implementing this feature is extremely easy. To
- show a tip, it is enough to just call #wxShowTip function
- like this:
-
- @code
- if ( ...show tips at startup?... )
- {
- wxTipProvider *tipProvider = wxCreateFileTipProvider("tips.txt", 0);
- wxShowTip(windowParent, tipProvider);
- delete tipProvider;
- }
- @endcode
-
- Of course, you need to get the text of the tips from somewhere - in the example
- above, the text is supposed to be in the file tips.txt from where it is read by
- the @e tip provider. The tip provider is just an object of a class deriving
- from #wxTipProvider. It has to implement one pure
- virtual function of the base class: #GetTip.
- In the case of the tip provider created by
- #wxCreateFileTipProvider, the tips are just
- the lines of the text file.
-
- If you want to implement your own tip provider (for example, if you wish to
- hardcode the tips inside your program), you just have to derive another class
- from wxTipProvider and pass a pointer to the object of this class to wxShowTip -
- then you don't need wxCreateFileTipProvider at all.
-
- You will probably want to save somewhere the index of the tip last
- shown - so that the program doesn't always show the same tip on startup. As you
- also need to remember whether to show tips or not (you shouldn't do it if the
- user unchecked "Show tips on startup" checkbox in the dialog), you will
- probably want to store both the index of the
- last shown tip (as returned by
- wxTipProvider::GetCurrentTip and the flag
- telling whether to show the tips at startup at all.
-
- In a tips.txt file, lines that begin with a # character are considered comments
- and are automatically skipped. Blank lines and lines only having spaces are also
- skipped.
-
- You can easily add runtime-translation capacity by placing each line of the
- tips.txt file inside the usual translation macro. For example, your tips.txt
- file would look like this:
-
- @code
- _("This is my first tip")
- _("This is my second tip")
- @endcode
-
- Now add your tips.txt file into the list of files that gettext searches
- for translatable strings. The tips will thus get included into your
- generated .po file catalog and be translated at runtime along with the rest of
- your application's translatable strings.
-
- Note1: Each line in the tips.txt file needs to strictly begin with exactly the
- 3 characters of underscore-parenthesis-doublequote, and end with
- doublequote-parenthesis, as shown above.
-
- Note2: Remember to escape any doublequote characters within the tip string with
- a backslash-doublequote.
-
- See the dialogs program in your samples folder for a working example inside a
- program.
