- @page overview_tips wxTipProvider Overview
 
- @tableofcontents
 
- 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 <em>tip provider</em>. 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.
 
- @note 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. Also, 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.
