Hello, We are testing Clutter and GTKClutterEmbed for maybe a rather unusual, but for us very logical use. We are building a 2D Medical Image Viewer, like MRICRO and ImageJ, for research purposes. Our first main objective is to have a tool specialized in ROI drawing, because we don't find any tool we find usable.
We are experimenting with OpenGL and we think Clutter is very suitable for our 2D needs. A single stage works perfectly to scroll,zoom and pan through a stack of slices. Now we are experimenting with MPR (Multi Planar Reformatted) Images, 3 views, Axial, Coronal, Sagittal views of the same stack. So we need 3 stages, because sometimes a very large zoom has to be separate and none overlapping between the 3 views right next to each other. So we started to use GTKClutterEmbed. But this is giving me big problems. Moving with the mouse from one to the other, events start to generate lots of errors like the one below, I connected some leave and enter events, and the pointers they return are not always the pointers of the stage the pointer is in. If I go from one embedded clutter stage to the other by moving first out of the window before entering the other embedded clutter widget, everything is working fine. Is this a bug or could it be my coding?
