Cannot change the default mouse cursor (0.8.3)

Postby Revington_ » Sat May 17, 2014 22:04

Hi All,

I'm trying to build a simple hello world app with python but setting the cursor image doesn't work.
I use a self compiled CEGUI/PYCEGUI 0.8.3 on windows 8.1 64bit:
I get this error:
PyCEGUI.System.getSingleton().getDefaultGUIContext().getMouseCursor().setDefaultImage("TaharezLook/MouseArrow")
TypeError: No to_python (by-value) converter found for C++ type: class CEGUI::MouseCursor

How can I set the default cursor image - or - is there a workaround for this bug?
At the moment lots of windows have no cursor and I have to call setMouseCursor on every window and even that doesn't work for all:
For example:
self.wnd.getTitlebar().setMouseCursor("Vanilla-Images/MouseArrow")

If I hover the mouse over the closing x the cursor disappears.

Greetings
Revington

PS
Thanks for this awesome GUI-Toolkit!

This indeed looks like a bug. Probably an oversight on my part in PyCEGUI.

However I looked into the sources and PyCEGUI is exposing CEGUI::MouseCursor so I am really puzzled why this doesn't work for you. Do any other classes cause errors? Right now I have no leads why just MouseCursor doesn't work, it's exposed exactly as any other class.

Everything else seems to work fine.

"After posting" :hammer: I found this issue report:
http://cegui.org.uk/mantis/view.php?id=996

Following the advice in the description fixed the problem for me.
Maybe its a problem with the default output from pyplusplus(not installed on my system) in ScriptModules/Python/bindings/output?

From the mantis bug report:
The problem is that the Py++ bindings try to return by value, but the mouse cursor is not copyable.

Why is it not returning by reference?
