Hi,
I've seen some discussions about the mouse cursor, but it doesn't answer my
question.
How can I set a cursor with the function setCursor. When I make a setCursor :
Code:
osgViewer::GraphicsWindow::MouseCursor mouseCursor;
mouseCursor = osgViewer::GraphicsWindow::DestroyCursor;
gw->setCursor(mouseCursor);
it does absolutely nothing.
The only way I can have a cursor, is to do :
Code:
while(!viewer.done())
{
viewer.frame();
gw->setCursor(mouseCursor);
}
And it does not a proper set, it sets the new cursor only when the mouse is not
moving.
I watched the source code, and I find it a bit confusing :
osgViewer/GraphicsWindowWin32.cpp
GraphicsWindowWin32::setCursor( MouseCursor mouseCursor )
Code:
if (mouseCursor != LeftRightCursor &&
mouseCursor != UpDownCursor &&
mouseCursor != TopLeftCorner &&
mouseCursor != TopRightCorner &&
mouseCursor != BottomLeftCorner &&
mouseCursor != BottomRightCorner)
{
_appMouseCursor = mouseCursor;
}
then :
Code:
case WM_NCHITTEST :
...
...
default:
if (_traits->useCursor && _appMouseCursor != InheritCursor)
setCursor(LeftArrowCursor);
break;
so if I set a cursor, _appMouseCursor will be equal to the new cursor, but will
be erased by the case WM_NCHITTEST;
Is there something I'm missing?
Thank you.
Romain.
