391 | /* Emacs's redisplay code could become confused if a frame's |
392 | visibility changes at arbitrary times. For example, if a frame is | |
393 | visible while the desired glyphs are being built, but becomes | |
394 | invisible before they are updated, then some rows of the | |
395 | desired_glyphs will be left marked as enabled after redisplay is | |
396 | complete, which should never happen. The next time the frame | |
397 | becomes visible, redisplay will probably barf. | |
398 | ||
399 | Currently, there are no similar situations involving iconified, but | |
400 | the principle is the same. | |
401 | ||
402 | So instead of having asynchronous input handlers directly set and | |
403 | clear the frame's visibility and iconification flags, they just set | |
404 | the async_visible and async_iconified flags; the redisplay code | |
405 | calls the FRAME_SAMPLE_VISIBILITY macro before doing any redisplay, | |
406 | which sets visible and iconified from their asynchronous | |
46a5c487 JB |
407 | counterparts. |
408 | ||
20a6c8d7 JB |
409 | Synchronous code must use the FRAME_SET_VISIBLE macro. |
410 | ||
411 | Also, if a frame used to be invisible, but has just become visible, | |
412 | it must be marked as garbaged, since redisplay hasn't been keeping | |
413 | up its contents. */ | |
