Retrieve Child Object

Postby mrGREEN » Wed May 13, 2009 11:45

Hi

For my app I need to retrieve all the Child Objects Names from a Father Object. I'm using a layout to load every single object.

Basically, what I'm doing is

Code: Select all

CEGUI::Window *cWindowFather = poWindowManager->getWindow("Root/MainWindow");
for (U32 k = 0; k < cWindowFather->getChildCount(); k++)
{
   CEGUI::Window *cWindowChild = cWindowFather->getChild(k);
   LOG ("name %s",cWindowChild->getName().c_str());
}


From the test that I'm running, "Root/MainWindow" has 18 child. I got only two child names, and then I got an exception. :cry:
Another weird thing if that one of the two names that I retrieve is wrong. I got something like "Root/MainWindow__auto_tilebar__".

I can't see where is the problem :!:

This is the Layout file that I'm using

Code: Select all

Re: Retrieve Child Object

Postby Jamarr » Wed May 13, 2009 16:16

There are a couple of issues here.

First, the reason your application is crashing is because you are using the API incorrectly. The getChild() function expects a user-defined window-id, but you are passing a child-index. You should be using getChildAtIdx() instead.

Second, you are forgetting (or never knew) about auto-windows. Auto-windows are child-windows defined in the .looknfeel file that are created automatically. The "Root/MainWindow__auto_tilebar__" is a perfectly valid child of a FrameWindow. By default a frame-window is composed of several child-windows including the titlebar among others. You can determine if a window is an auto-window or not by calling isAutoWindow() on the window in question.
If somebody helps you by replying to your thread, upvote him/her as a thanks! Make sure to include your CEGUI.log and everything you tried when posting! And remember that we are not magicians!
