[ocemp-devel] Style changes in OcempGUI

[Marcus v. A. <ma...@sy...>]

Hello,

the first version of OcempGUI (up to 0.0.6) had an ugly style support.
This will change with the upcoming version 0.0.7, in which the Style
class resides in the widget package.
Every widget now can support several states with the new design, so a
fine grained visible diversion of the look and feel can be made.

This also means, that the next release will not be compatible with
previous releases. I apologize for those circumstances, but the benefit
is much higher than the problems with the broken compatibility.

First parts of those changes are checked in today and seem to work well.


Feedback is welcome.

Regards
Marcus

Marcus:

Your Ocemp GUI package looks very interesting, and thank you for
producing and releasing it.

However, in my initial testing, some of your demos did not work for
me.  Here are the results I got:

[exception backtrace]

right, this is a critical error based on less testing. Many constructors
of the widgets call update() on creation in 0.0.6. The ToggleButton
inherits from Button, which calls update() and then tries to run the
ToggleButton.draw() method. A really dumb error, I've overseen.
It is fixed in the current CVS version and will go into 0.0.7.

If you however want to get rid of it, please go through the various
widgets and encapsulate the 'self.update()' line in the __init__()
methods in a try-except statement:

try:
    self.update()
except:
    pass

Or simply use the CVS version, which seems to be pretty stable.
Sorry for those circumstances.

Regards
Marcus
