2002-02-05 Michael Natterer <mitch@gimp.org> Removed pointer grabbing from all tools: * app/tools/gimptool.[ch]: added "gboolean perfectmouse" which defaults to FALSE but can be set to TRUE in a tool's instance_init function. * app/display/gimpdisplayshell-callbacks.c: look at active_tool->perfectmouse and gimprc.perfectmouse and do the pointer grab/ungrab here. The pointer is now grabbed right before dispatching the button_press to the tool and ungrabbed after the tool's button_release has returned. It is also grabbed *always*, not only if tool->state got ACTIVE by button_press, which makes it all much simpler... * app/tools/gimpbezierselecttool.c * app/tools/gimpblendtool.c * app/tools/gimpbucketfilltool.c * app/tools/gimpbycolorselecttool.c * app/tools/gimpclonetool.c * app/tools/gimpcolorpickertool.c * app/tools/gimpcroptool.c * app/tools/gimpeditselectiontool.c * app/tools/gimpfliptool.c * app/tools/gimpfreeselecttool.c * app/tools/gimpfuzzyselecttool.c * app/tools/gimpinktool.c * app/tools/gimpiscissorstool.c * app/tools/gimpmagnifytool.c * app/tools/gimpmeasuretool.c * app/tools/gimpmovetool.c * app/tools/gimppainttool.c * app/tools/gimppathtool.c * app/tools/gimprectselecttool.c * app/tools/gimpselectiontool.c * app/tools/gimptexttool.c * app/tools/gimptransformtool.c: removed gdk_pointer_grab()/ungrab() calls all over the place. Also removed inclusion of "display/gimpdisplayshell.h" from most of them.
