[solved] ListBoxTextItem::setText() not updating window

Postby Mikademus » Wed Mar 18, 2009 21:01

In my learning CEGUI under OGRE I've made a spiffy FPS-related info window consisting of a MultiColumnList. The design went nice, and it draws, the only problem is that it doesn't update the text fields when calling setText() on them*.

Or rather, it seems that if will update once, and then not accept new updates. This makes my FPS counter somewhat dull and uninformative, I'm sad to say :(

Is this an issue, or am I doing something wrong?


* If calling every frame it will update the first time, if calling every second starting the second after booting the app it will actually never be updated... O.o

The MCL does not update automatically; this is by design to avoid performance issues when updating a lot of items. You need to do this after you've finished updating the list:

Code: Select all

mcl->handleUpdatedItemData();

Thanks! That was it!

I was going to make an article at the wiki about using MCLs, but I couldn't register... :( Pity, since CEGUI really needs more documentation and guides.
