779 | /* Emacs's redisplay code could become confused if a frame's |
780 | visibility changes at arbitrary times. For example, if a frame is | |
781 | visible while the desired glyphs are being built, but becomes | |
782 | invisible before they are updated, then some rows of the | |
783 | desired_glyphs will be left marked as enabled after redisplay is | |
784 | complete, which should never happen. The next time the frame | |
785 | becomes visible, redisplay will probably barf. | |
786 | ||
787 | Currently, there are no similar situations involving iconified, but | |
788 | the principle is the same. | |
789 | ||
790 | So instead of having asynchronous input handlers directly set and | |
791 | clear the frame's visibility and iconification flags, they just set | |
792 | the async_visible and async_iconified flags; the redisplay code | |
793 | calls the FRAME_SAMPLE_VISIBILITY macro before doing any redisplay, | |
794 | which sets visible and iconified from their asynchronous | |
46a5c487 JB |
795 | counterparts. |
796 | ||
20a6c8d7 JB |
797 | Synchronous code must use the FRAME_SET_VISIBLE macro. |

800 | it must be marked as garbaged, since redisplay hasn't been keeping | |
9628b887 KL |
