Hi,
While trying to understand the zoom function to apply it to other GUI
objects, I studied the bng and tgl objects, and in the process came up
with a solution that fixed both.
For the iem_gui objects only the basic generic GUI parameters are
available in a struct; x & y position coordinates, height and width. All
other GUI dimensions are not accessible outside the drawing functions.
The only option to get a correct zoom is to apply the zoom-factor to all
appropriate dimension values in all GUI functions.
At least for bng I have this working. With some more refactoring this
could be applied without adding too much to the declared mess in the
objects code.
Greetings,
Fred Jan
