1373 Output a widget hierarchy. This can safely call itself recursively.
|
|
442
|
1374
|
|
|
1375 The complexity of outputting layouts is deciding whether to do it or
|
|
|
1376 not. Consider a layout enclosing some text, the text changes and is
|
|
|
1377 marked as dirty, but the enclosing layout has not been marked as
|
|
|
1378 dirty so no updates occur and the text will potentially be truncated.
|
|
|
1379 Alternatively we hold a back pointer in the image instance to the
|
|
|
1380 parent and mark the parent as dirty. But the layout code assumes that
|
|
|
1381 if the layout is dirty then the whole layout should be redisplayed,
|
|
|
1382 so we then get lots of flashing even though only the text has changed
|
|
|
1383 size. Of course if the text shrinks in size then we do actually need
|
|
|
1384 to redisplay the layout to repaint the exposed area. So what happens
|
|
|
1385 if we make a non-structural change like changing color? Either we
|
|
|
1386 redisplay everything, or we redisplay nothing. These are exactly the
|
|
|
1387 issues lwlib has to grapple with. We really need to know what has
|
|
|
1388 actually changed and make a layout decision based on that. We also
|
|
|
1389 really need to know what has changed so that we can only make the
|
|
|
1390 necessary changes in update_subwindow. This has all now been
|
|
|
1391 implemented, Viva la revolution!
