1999-11-02 Federico Mena Quintero <federico@redhat.com> * src/print-preview.c (PreviewMode): Renamed the move modes to MODE_MOVE and MOVE_MODE_DRAGGING. (preview_canvas_button_press): Split the event handling code between several functions. Rationale: we will want drag-zoom and we need different modes for this, and the code in a single function would get unwieldy. In addition, grab the pointer and use GDK_POINTER_MOTION_HINT_MASK for better behavior. (PrintPreview): Added fields for drag anchor and drag offset. (drag_to): New function to drag/scroll. (create_preview_canvas): Connect to the different event handlers. (do_zoom): We do not need to re-render the page; just set the zoom factor. Also, use exponential zooming for better behavior. * src/cursors.h: Moved the cursor #defines to an enum. This way we can check for a max value in cursor_get(). Moved the cursor array to the .c file and made it private. * src/cursors.c (cursors_init): Added sanity check so that all cursors are defined. (cursor_get): New function to get a cursor based on its type. (cursors): Added hand cursors. * src/pixmaps/cursor_hand_{open,closed}.xpm: Added hand cursors. svn path=/trunk/; revision=1365
