When using the mouse wheel inside a viewport (ListBox or Viewport directly) the vertical scroll bar is immediately scrolls to the upper left regardless of
the position of the scrolling / the amount scrolled.
This only happens in VST mode, in standalone mode it works fine (it also works fine in Mac standalone / AU / VST )
I’ve found that in the func. doMouseWheel() the line:
A similar issue is discribed here: When more than one Juce-based plugin is opened only the last opened will get valid mouse messages.
I just added this Component to the Juce demo plugin where the mousewheel worked fine with the Viewport:
class Container : public Viewport
{
public:
Container()
{
editor.setSize(50, 200);
setViewedComponent(&editor, false);
}
private:
TextEditor editor;
};
It was sized to show a scroll bar (50x150). Could it be you ran into the issue described above?
How is this even possible? I thought Windows used standard generic drivers for mice (the vendor specific driver can be installed to gain additional features but without it, the generic driver provides basic functions). If this is the case then mouse behavior should be independent of the application. Unless, your mouse has installed some kind of special software that treats applications differently. Logitech for example can do this, customize the mouse for each app (usually a game).
