update screen

How can I update or refresh display after changing text or another value ?

[Joel Bodenmann]

There is no global "update everything" command. The way that GWIN is build implies that each element is only redrawn when needed to. If you call gwinSetText() the corresponding widget(s) will be redrawn automatically.
If you implement a custom widget that has a setValue() method you are supposed to call _gwinUpdate() in that function.
this means that if you have the need to manually update widgets or the entire display you are doing something wrong.

I hope that helps. Let us know if you have any other questions.
