Update of /project/mcclim/cvsroot/mcclim/Backends/gtkairo In directory clnet:/tmp/cvs-serv23372
Modified Files: clim-fix.lisp event.lisp gtk-ffi.lisp medium.lisp port.lisp Log Message: Low-flicker drawing: Double-buffer everything.
* clim-fix.lisp (HANDLE-REPAINT, HIGHLIGHT-OUTPUT-RECORD-RECTANGLE): Use FORCE-OUTPUT on the SHEET instead of MEDIUM-FORCE-OUTPUT.
* event.lisp (EXPOSE-HANDLER): If the mirror has a valid double buffering pixmap, has just blit the exposed rectangle to screen. Else, this must be the first redraw after initialization (A) or resize (B), so enqueue a window repaint event to get things going. For case A, clear the actual widget, since the frontend assumes mirrors to be filled with the background color if it never handles repaints on it. In case B, mark the pixmap as complete again.
* gtk-ffi.lisp (gdk_window_invalidate_rect): New declaration.
* medium.lisp (SYNC-SHEET): Mark the medium as dirty. (MEDIUM-FINISH-OUTPUT): Call medium-force-output after flushing the cairo surface. (MEDIUM-FORCE-OUTPUT): Remove the medium from the dirty table and invalidate the mirror. (INVALIDATE-MIRROR): For widget mirrors (with a double buffering pixmap), send an expose event.
* port.lisp (*DOUBLE-BUFFERING-P*): New variable. (PORT): New slot DIRTY-MEDIUMS. (WIDGET-MIRROR): New slots PORT, BUFFERING-PIXMAP, BUFFERING-PIXMAP-P. (DRAWABLE-MIRROR): Additional accessor for the drawable slot, called MIRROR-REAL-DRAWABLE. ((MIRROR-REAL-DRAWABLE WIDGET-MIRROR)): Return the gdk window. (MIRROR-DRAWABLE): New method. Return or install the double buffering pixmap if *DOUBLE-BUFFERING-P* is enabled. Else return the real drawable. (REALIZE-WINDOW-MIRROR, REALIZE-MIRROR): Set the mirror's PORT slot. ((DESTROY-MIRROR MIRRORED-SHEET-MIXIN)): Free the double buffering pixmap. (RESET-MEDIUMS): Create a new double buffering pixmap for current size, copy over the old content, mark the pixmap as incomplete, and free the old one. (PORT-SET-MIRROR-REGION): Call RESET-MEDIUMS only after the resize has happened. (PORT-SET-MIRROR-TRANSFORMATION): No need to call RESET-MEDIUMS. (PORT-FORCE-OUTPUT): Call MEDIUM-FORCE-OUTPUT for all dirty mediums. Don't exit on X errors:
* gtk-ffi.lisp (_gdk_error_warnings, _gdk_error_code, XGetErrorText): New declarations. * event.lisp (DRIBBLE-X-ERRORS): New function. (GTK-MAIN-ITERATION): Call DRIBBLE-X-ERRORS.
* port.lisp (initialize-instance): Turn off `gdk-error-warnings', thereby disabling the GTk+'s "exit on error" behaviour. (PORT-FORCE-OUTPUT): Call DRIBBLE-X-ERRORS. Implement the weird pointer tracking code CLIM-CLX has:
* port.lisp (PORT): New slot POINTER-GRAB-SHEET. (PORT-GRAB-POINTER): Set POINTER-GRAB-SHEET. (PORT-UNGRAB-POINTER): Clear POINTER-GRAB-SHEET if it is equal to the ungrabbing sheet. (DISTRIBUTE-EVENT :AROUND): Send events to the grabbing sheet no matter what.
Misc: * event.lisp (ENTER-HANDLER): Set PORT-POINTER-SHEET manually, fixing a problem with the Drag and Drop demo.
* medium.lisp (SYNC-TRANSFORMATION): Error out on invalid transformation -before- installing them into the cairo context. ((SYNC-INK FLIPPING-INK)): Removed unused binding of allocation size.
* port.lisp (PORT-MIRROR-WIDTH, PORT-MIRROR-HEIGHT): Implemented.
