[gtk-vnc-devel] nevermind... my mod screwed up scaling...

[Rob Stoddard <rstoddard telanetix com>]

I found out what I did that messed up the scaling in the widget.    I 
was trying to get the widget to work properly when it's created and 
scaling is set during the gtk main loop, which, by the way, causes it to 
crash because the GL scaling expects the vncdisplay.c priv->image 
pointer to be valid.  If it isn't, the program crashes.  Suppose you 
create the widget in response to a user action, and set scaling 
immediately, then the program will crash.  I was trying to make the 
program not crash, and in so doing screwed up scaling...  but now I've 
found a happy medium by adding the following (in bold for those who 
support it):



static void rescale_display(VncDisplay *obj, gint width, gint height)
{
       VncDisplayPrivate *priv = obj->priv;

       if (*(priv->image || priv->gl_enabled) &&* priv->allow_scaling &&
           (priv->fb.height != width ||
            priv->fb.height != height))
               scale_display(obj, width, height);
       else if (priv->gl_enabled) {
               void *data;
               priv->gl_enabled = 0;
/* and so on */


Where I screwed up was I had only added the priv->image  and didn't 
check to see if gl_enabled was set...  That caused it to do some pretty 
odd stuff.
