Bump.
I've made a tiny bit of progress with dialog positioning, but I am
still having a hard time understanding how sizes and positioning are
done.
I see these two variables seem very important to the process, but I
don't understand how they get set or how to fill them with the proper
values.
ih->currentwidth
ih->currentheight
I've found the function
void iupdrvBaseLayoutUpdateMethod(Ihandle *ih)
It looks like this is a good time to set the size and position of
widgets. However, I don't think the ih->currentwidth and
ih->currentheight values are valid. I don't think Iup yet has proper
sizing information for my widgets, like the minimum fit size for a
button or label is. And I don't understand how the dialog finally gets
its total fit information.
Thanks,
Eric
