Re: Updating windows in IUP

["Luciano de Souza" <luchyanus@...>]

Antônio,

What I sent you is not exactely a program, but only a simple test writen to 
understand the options I have using IUP. As I told you before, I am blind. I 
am not so interested in color indeed, but the bgcolor attribute is so easy 
to use that I decide to test it. My screen reader can inform the change of 
colors on the window.

Since it is only a test, don't search a well-built code. Actually, in this 
example, the button changing the color is "Agendar", in the code identified 
by al_bt_schedule. So the lines you need to observe are from "function 
al_bt_schedule". You are right: only typing "root.bgcolor = '200 200 200', I 
can change the color. However, is it occur immediately and for all the 
screen? I think no, but my screen reader or I can be craizy. As long as I 
move the focus with the tabulations, one part of the screen is changed, 
becoming wholly changed, only when I move the focus to another TAB.

You can see anyway how IUP will help me in programin. A graphical interface 
created by someone who can't see anything is a very differnt thing, don't 
you? But, from waht I am able to understand, although the normal vision is 
very important, to program IUP codes is perhaps suficient to imagine. 
Furthermore, it is one of my first examples. Certainly, I will improve my 
skills. Despite the non attractive layout, for the screen readers, the 
navigation among the controls is very simple.
