1290 Output a widget hierarchy. This can safely call itself recursively.
|
|
442
|
1291
|
|
|
1292 The complexity of outputting layouts is deciding whether to do it or
|
|
|
1293 not. Consider a layout enclosing some text, the text changes and is
|
|
|
1294 marked as dirty, but the enclosing layout has not been marked as
|
|
|
1295 dirty so no updates occur and the text will potentially be truncated.
|
|
|
1296 Alternatively we hold a back pointer in the image instance to the
|
|
|
1297 parent and mark the parent as dirty. But the layout code assumes that
|
|
|
1298 if the layout is dirty then the whole layout should be redisplayed,
|
|
|
1299 so we then get lots of flashing even though only the text has changed
|
|
|
1300 size. Of course if the text shrinks in size then we do actually need
|
|
|
1301 to redisplay the layout to repaint the exposed area. So what happens
|
|
|
1302 if we make a non-structural change like changing color? Either we
|
|
|
1303 redisplay everything, or we redisplay nothing. These are exactly the
|
|
|
1304 issues lwlib has to grapple with. We really need to know what has
|
|
|
1305 actually changed and make a layout decision based on that. We also
|
|
|
1306 really need to know what has changed so that we can only make the
|
|
|
1307 necessary changes in update_subwindow. This has all now been
|
|
|
1308 implemented, Viva la revolution!
