| 428 | 322 it! There are random dependencies between functions, there is a |
| 323 total lack of genericity, even though it initially appears to be | |
| 324 generic. It should all be junked and begun again. Building tabs are | |
| 325 an example - in theory we should be able to reuse a lot of the | |
| 326 general stuff because we want to put labels of whatever toolkit we | |
| 2641 | 327 are using in the tab. Instead we have to hack it by hand. ]] |
| 328 While lwlib is a hairy crock, whoever wrote that seems to misunderstand | |
| 329 Falk's tab control widget. The tab control widget has *two* kinds of | |
| 330 children: *widgets*, which all occupy a *single* pane below the row of | |
| 331 tabs---this is where the labels created in build_tabs_in_widget go, and | |
| 332 *gadgets*, the tabs themselves, which do *not* draw themselves, but | |
| 333 rather are drawn by the control. In fact, in XEmacs the true widget | |
| 334 children are *never* visible! So this case is not a problem in the | |
| 335 design of lwlib, but rather of Falk's widget. -- sjt */ | |
