<H1 ALIGN="RIGHT">G - Migrating Code from FLTK 1.0.x</H1>
|
|
|
|
<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.
|
|
|
|
<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>
|
|
|
|
<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
|
|
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>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
|
|
HREF="Fl_Pixmap.html"><TT>Fl_Pixmap</TT>, and <A
|
|
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.
|
|
|
|
<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.
