|
There is(was?) a bug in Sun's XmuLookupStandardColormap
|
||
|
|
X library function.
|
||
|
|
If you compile togl.c with the SOLARIS_BUG symbol defined (-DSOLARIS_BUG)
|
||
|
|
this function call will be omitted.

Before Tk 8.5,
|
||
|
|
Tk does not support true fullscreen windows.
|
||
|
|
Consequenly the full-screen stereo,
|
||
|
|
that gaming graphics cards support (ATI Radeon, NVidia GeForce),
|
||
|
|
won't be added until sometime after Tk 8.5 is available.
|
||
|
|
Fullscreen stereo on workstation graphics cards
|
||
|
|
(ATI FireGL, NVidia Quadro, Matrix Parhelia, 3Dlabs Wildcat)
|
||
|
|
does work.

|

<dd>
|
||
|
|
First call <code>Togl_MakeCurrent</code> to make sure you have the
|
||
|
|
right OpenGL context and device context set,
|
||
|
|
then call <code>wglGetCurrentDC</code>.

<a name="python"><b>How do I use Togl from Python?</b></a>
|
||
|
|
<dd>
|
||
|
|
The Togl source distribution comes with a <code>Togl.py</code> file
|
||
|
|
that provides a Tkinter-style Togl widget.
|
||
|
|
And for Togl callbacks that are C functions,
|
||
|
|
there is a <code>toglpy.h</code> file that provides a function
|
||
|
|
that converts a Python object into its corresponding Togl widget:
|
||
|
|
<blockquote>
|
||
|
|
<code>Togl *getToglFromWidget(PyObject *widget)</code>
|
||
|
|
</blockquote>
|
||

|
||
|
|
<dd>
|
||
|
|
Yes, Togl works as is (except for the bitmap font support for X11 and Aqua).
|
||
|
|
From <a href="http://wiki.tcl.tk/1218">Joe English</a>:
|
||
|
|
<blockquote>
|
||
|
|
Complex "owner-draw" widgets like tkZinc,
|
||
|
|
or the text and canvas widgets,
|
||
|
|
really don't benefit much from themability,
|
||
|
|
so there's no reason to rewrite them.
