Rollover on tree item and other tree item difficulties

Postby netamaster » Thu Mar 20, 2008 11:10

Hello everybody.
I'm currently working on a chat system that uses CEGUI and some Tree, TreeItem elements in a List object.

- First thing is that I have an item of type CEGUI::TreeItem *item.
I wanted to subscribe EventListener of mouse event that uses some rollover efect to change the tree item in the list or to put an tooltip text - when mouse is over to show the tooltip text displaying some information.
A possible solution could be listener for the event CEGUI::Window::EventMouseMove, but i don't know how to get item's position in window etc.
If there is a simple rolloveritem and rolloutitem functions it would be the best solution for me.

- Another thing is that when i tryed to load the layout of an agenda there was an error that fired: "GUILayout_xmlHandler::startElement - layout loading has been aborted since no WindowFactory is available for NewData/Tree objects". I looked and i found the definition in the looknfeel file that follows:

Unfortunately I am not aware of any simple means of achieving notifications that could be used for roll-over effects within the Tree. Having said this, I am not overly familiar with this particular widget (except in so much as it closely models the old style listbox). For me it is completely inexcusable that the tree, being a new widget, was created using the out-dated approach that it does - it should have been created using the newer ItemList approach, thus allowing more advanced abilities such that you are asking about.

It sounds like you are missing a mapping in the scheme file for the type "NewData/Tree" - defining a skin is not enough, this must then be mapped to a registered 'base' type and a registered WindowRenderer, to create a final type that can be instantiated.
