Distille the Native File Chooser files down into a single file. I would like to avoid that the common API runs out of sync between platforms (no code doubling - there was already a mismatch with 'const'), and that the users may wonder which file to include. Please check this on WIN32 and Unix. It does work on OS X.

/**
|
||||||
|
This class lets an FLTK application easily and consistently access
|
||||||
|
the operating system's native file chooser. Some operating systems
|
||||||
|
have very complex and specific file choosers that many users want
|
||||||
|
access to specifically, instead of FLTK's default file chooser(s).
|
||||||
|
|
||||||
|
In cases where there is no native file browser, FLTK's own file browser
|
||||||
|
is used instead.
|
||||||
|
|
||||||
|
To use this widget, use the following include in your code:
|
||||||
|
\code
|
||||||
|
#include <FL/Fl_Native_File_Chooser.H>
|
||||||
|
\endcode
|
||||||
|
|
||||||
|
The following example shows how to pick a single file:
|
||||||
|
\code
|
||||||
|
// Create and post the local native file chooser
|
||||||
|
#include <FL/Fl_Native_File_Chooser.H>
|
||||||
|
[..]
|
||||||
|
Fl_Native_File_Chooser fnfc;
|
||||||
|
fnfc.title("Pick a file");
|
||||||
|
fnfc.type(Fl_Native_File_Chooser::BROWSE_FILE);
|
||||||
|
fnfc.filter("Text\t*.txt\n"
|
||||||
|
"C Files\t*.{cxx,h,c}");
|
||||||
|
fnfc.directory("/var/tmp"); // default directory to use
|
||||||
|
// Show native chooser
|
||||||
|
switch ( fnfc.show() ) {
|
||||||
|
case -1: printf("ERROR: %s\n", fnfc.errmsg()); break; // ERROR
|
||||||
|
case 1: printf("CANCEL\n"); break; // CANCEL
|
||||||
|
default: printf("PICKED: %s\n", fnfc.filename()); break; // FILE CHOSEN
|
||||||
|
}
|
||||||
|
\endcode
|
||||||
|
|
||||||
|
<B>Platform Specific Caveats</B>
|
||||||
|
|
||||||
|
- Under X windows, it's best if you call Fl_File_Icon::load_system_icons()
|
||||||
|
at the start of main(), to enable the nicer looking file browser widgets.
|
||||||
|
Use the static public attributes of class Fl_File_Chooser to localize
|
||||||
|
the browser.
|
||||||
|
- Some operating systems support certain OS specific options; see
|
||||||
|
Fl_Native_File_Chooser::options() for a list.
