Dave,
The code that moves the text is visible e.g. in the resize function
in lib/Xm-2.1/ToggleB.c where Lab_TextRect_x(w) gets set.
This really implies that the superclass (XmLabel) does all the work
of drawing the text, and has sufficient support so XmToggleButton
can get away with that; and Toggle only takes care of the position
calculation and drawing the indicator.
For your information, there's similar interaction between XmLabel
and XmPushButton for accelerators. (There's no reason why XmLabel
has accelerators except its subclasses.)
If you want to start single-stepping this, be sure not to end up in
a case where you freeze your whole screen. On my (linux) system, I
would have to run this in an Xnest X server to prevent the grabs
from blocking me; maybe this is different on your (windows?) system.
