Suggestion: Option to disable rendering

[Daid]

I would like to suggest an option to disable rendering of an widget, until enabled again.

Currently I'm putting elements in a listbox, but during this inserting the listbox gets drawn repeatedly, causing flicker. I worked around this by:

gwinSetVisible(ghFileList, FALSE);
for each file:
    gwinListAddItem(ghFileList, fn, TRUE);
gwinSetVisible(ghFileList, TRUE);

However, gwinSetVisible FALSE causes the listbox area to be cleared on the screen. So it's empty for a while.

If I hack this up to:

ghFileList->flags &= ~2;//Disable the visibility flag.
for each file:
    gwinListAddItem(ghFileList, fn, TRUE);
gwinSetVisible(ghFileList, TRUE);

I get the result I'm looking for, in a very dirty way.

Thoughts?

I understand the problem that you are describing. I'll try to come up with a solution asap.

This feature has finally been added: https://bitbucket.org/Tectu/ugfx/commit ... 5cc557c2f7

As we couldn't come up with any usecase for other widgets than the list, it has been implemented directly into the list widget API.
