<P>This appendix describes the differences between the FLTK
|
|
|
|
|
1.0.x and FLTK 1.1.x functions and classes.</P>

<H2>Color Values</H2>
|
|
|
|
|
|
|
|
|
|
<P>Color values are now stored in a 32-bit unsigned integer
|
|
|
|
|
instead of the unsigned character in 1.0.x. This allows for the
|
|
|
|
|
specification of 24-bit RGB values or 8-bit FLTK color indices.
|
|
|
|
|
|
2005-12-19 16:33:08 +03:00
|
|
|
<P><TT>FL_BLACK</TT> and <TT>FL_WHITE</TT> now remain black and
|
|
|
|
|
white, even if the base color of the gray ramp is changed using
|
|
|
|
|
<A HREF="Fl.html#Fl.background"><TT>Fl::background()</TT></A>.
|
|
|
|
|
<TT>FL_DARK3</TT> and <TT>FL_LIGHT3</TT> can be used instead to
|
|
|
|
|
draw a very dark or a very bright background hue.</P>
|
|
|
|
|
|
|
|
|
|
<P>Widgets use the new color symbols <TT>FL_FORGROUND_COLOR</TT>,
|
|
|
|
|
<TT>FL_BACKGROUND_COLOR</TT>, <TT>FL_BACKGROUND2_COLOR</TT>,
|
|
|
|
|
<TT>FL_INACTIVE_COLOR</TT>, and <TT>FL_SELECTION_COLOR</TT>.

<H2>Cut and Paste Support</H2>
|
|
|
|
|
|
|
|
|
|
<P>The FLTK clipboard is now broken into two parts - a local
|
|
|
|
|
selection value and a cut-and-paste value. This allows FLTK to
|
|
|
|
|
support things like highlighting and replacing text that was
|
|
|
|
|
previously cut or copied, which makes FLTK applications behave
|
|
|
|
|
like traditional GUI applications.

<H2>File Chooser</H2>
|
2001-11-27 02:50:30 +03:00
|
|
|
|
|
|
|
|
<P>The file chooser in FLTK 1.1.x is significantly different
|
|
|
|
|
than the one supplied with FLTK 1.0.x. Any code that directly
|
2002-03-25 21:30:16 +03:00
|
|
|
references the old <TT>FCB</TT> class or members will need
|
|
|
|
|
to be ported to the new <A
|
|
|
|
|
HREF="Fl_File_Chooser.html"><TT>Fl_File_Chooser</TT></A>
|
|
|
|
|
class.</P>

<H2>Function Names</H2>
|
|
|
|
|
|
|
|
|
|
<P>Some function names have changed from FLTK 1.0.x to 1.1.x in
|
2002-06-24 19:22:57 +04:00
|
|
|
order to avoid name space collisions. You can still use the old
|
|
|
|
|
function names by defining the <CODE>FLTK_1_0_COMPAT</CODE>
|
|
|
|
|
symbol on the command-line when you compile
|
|
|
|
|
(<CODE>-DFLTK_1_0_COMPAT</CODE>) or in your source, e.g.:
|
|
|
|
|
|
|
|
|
|
<UL><PRE>
|
|
|
|
|
#define FLTK_1_0_COMPAT
|
|
|
|
|
#include <FL/Fl.H>
|

|
|
|
#include <FL/Enumerations.H>

#include <FL/filename.H>
|
|

</PRE></UL>

<H2>Image Support</H2>
|
|
|
|
|
|
|
|
|
|
<P>Image support in FLTK has been significantly revamped in
|
|
|
|
|
1.1.x. The <A HREF="Fl_Image.html"><TT>Fl_Image</TT></A> class
|
|
|
|
|
is now a proper base class, with the core image drawing
|
|
|
|
|
functionality in the <A
|
|
|
|
|
HREF="Fl_Bitmap.html"><TT>Fl_Bitmap</TT></A>, <A
|
2002-03-27 15:40:59 +03:00
|
|
|
HREF="Fl_Pixmap.html"><TT>Fl_Pixmap</TT></A>, and <A
|
2002-03-25 21:30:16 +03:00
|
|
|
HREF="Fl_RGB_Image.html"><TT>Fl_RGB_Image</TT></A> classes.
|
|
|
|
|
|
|
|
|
|
<P>BMP, GIF, JPEG, PNG, XBM, and XPM image files can now be
|
|
|
|
|
loaded using the appropriate image classes, and the <A
|
|
|
|
|
HREF="Fl_Shared_Image.html"><TT>Fl_Shared_Image</TT></A> class
|
|
|
|
|
can be used to cache images in memory.
|
2001-11-27 02:50:30 +03:00
|
|
|
|
2002-03-25 21:30:16 +03:00
|
|
|
<P>Image labels are no longer provided as an add-on label type.
|
|
|
|
|
If you use the old <TT>label()</TT> methods on an image, the
|
|
|
|
|
widget's <TT>image()</TT> method is called to set the image
|
|
|
|
|
as the label.
|
2001-11-27 02:50:30 +03:00
|
|
|
|
2002-04-26 14:33:03 +04:00
|
|
|
<P>Image labels in menu items must still use the old labeltype
|
|
|
|
|
mechanism to preserve source compatibility.

<H2>Keyboard Navigation</H2>
|
|
|
|
|
|
|
|
|
|
<P>FLTK 1.1.x now supports keyboard navigation and control with
|
|
|
|
|
all widgets. To restore the old FLTK 1.0.x behavior so that only
|
|
|
|
|
text widgets get keyboard focus, call the <A
|
|
|
|
|
HREF="Fl.html#Fl.visible_focus"><CODE>Fl::visible_focus()</CODE></A>
|
|
|
|
|
method to disable it:
|
|
|
|
|
|
|
|
|
|
<UL><PRE>
|
|
|
|
|
Fl::visible_focus(0);
