[osg-users] Cursor problem under Windows
Hi all,
Currently (the SVN version of OSG), hidding the cursor under Windows has no
effect. Setting cursor to false on the traits or making something like :
osgViewer::ViewerBase::Windowswindows;
viewer.getWindows(windows);
for (osgViewer::ViewerBase::Windows::iterator itr = windows.begin(); itr !=
windows.end(); ++itr)
{
(*itr)-useCursor(false);
}
Doesn't work, I always see the cursor...
Any idea on which modification has break things ? The same code was working
for me some weeks ago, but I can't tell which revision it was...
Thanks !
Best regards,

Re: [osg-users] Cursor problem under Windows
I have an update, using :
osgViewer::ViewerBase::Windowswindows;
viewer.getWindows(windows);
for (osgViewer::ViewerBase::Windows::iterator itr = windows.begin(); itr !=
windows.end(); ++itr)
{
//(*itr)-useCursor(false);
(*itr)-setCursor(osgViewer::GraphicsWindow::MouseCursor::NoCursor);
}
Instead of setting useCursor(false) works, the cursor is invisible.

Re: [osg-users] Cursor problem under Windows
Hi Serge,
Good to hear you got it working, useCursor(false) should still work
though... so that is a bug. Can you say which versions of the OSG
that useCursor(false) was still working on? Have you tried out other
platforms?
Robert.

Re: [osg-users] Cursor problem under Windows
Hi Robert,
I've only tried it on Windows, and about the version where it was working,
maybe it was 2 or 3 weeks ago, but I am really not sure, I've made a fresh
OSG compile last night from the SVN but I can't remember when I dit it the
previous time... :/
I'm really sorry to not investigate further but I don't have time currently,
I'll try to give it a look next week.
Best regards,

Re: [osg-users] Cursor problem under Windows
Hi Robert Serge,
Here is the offending line:
void GraphicsWindowWin32::setCursorImpl( MouseCursor mouseCursor )
{
if (_mouseCursor != mouseCursor)
{
_mouseCursor = mouseCursor;
HCURSOR newCursor = getOrCreateCursor( mouseCursor);
if (newCursor == _currentCursor) return;
_currentCursor = newCursor;
_traits-useCursor = (_currentCursor != NULL); // Problem:
Changing useCursor when setCursorImpl is called
if (_mouseCursor != InheritCursor)
::SetCursor(_currentCursor);
}
}
It looks like this line isn't really necessary, but if it is desired to
change the useCursor mode when a cursor is set, it should be done in
setCursor, and not setCursorImpl.
void GraphicsWindowWin32::setCursor( MouseCursor mouseCursor )
{
_appMouseCursor = mouseCursor;
setCursorImpl(mouseCursor);
_traits-useCursor = (_currentCursor != NULL); // Line belongs
here instead (if this behavior is desired).
}
From a design perspective, I think useCursor and setCursor methods
should be orthogonal. Changing a cursor should not affect the useCursor
state of the window. Orthogonal designs tend to be more flexible. So if
it were up to me, I would simply delete the line with the result of a
slight change in semantics of the setCursor function.
Serge, try moving the indicated line to the indicated function. If that
doesn't work, delete it entirely. Some other code may be calling
setCursor behind your back and turning it back on.
Regards,
Mark
