-----Message d'origine----- De : Alex Harui [mailto:aha...@adobe.com] Envoyé : samedi 16 novembre 2013 19:32 À : dev@flex.apache.org Objet : Re: Air Stage Text Issue I can try to ask the engineer who worked on it to see if he remembers, but I would guess the following: 1) There was hope that AIR would provide a solution 2) I'm not sure proxying would handle text selection. 3) I'm not sure proxying would handle partially occluded text inputs. You're welcome to take a shot at it. Adobe generally didn't like half-baked solutions so if it there was no solution for partially-occluded text inputs it wouldn't provide a solution at all, but maybe it is worth offering a solution for folks who won't ever partially occlude their text inputs (which is probably a lot of folks). But before you go work on that, can you look at the most recent mustella failures? I think there is a new DataGrid failure. -Alex On 11/16/13 5:17 AM, "Maurice Amsellem" <maurice.amsel...@systar.com> wrote: >Hi, > >I am currently working on the issue about StageTextInput not scrolling >on >mobile: >https://issues.apache.org/jira/browse/FLEX-33166 > > >Debugging the SDK source code, it appears that "proxying" the >StageTextInput with a bitmap is already in place (see class >StyleableStageText). > >However, the proxy bitmap is shown in only very specific situations: >- a stage animation that contains the stage text is playing (example: >Touch "throw" animation, that happens when you *release* your finger >after swiping ) >- popup is opened , in which case all text input below in the z-order >are proxied to bitmaps > >Another rather "radical" approach, which has been suggested by some ( >DarkStone, Flexicious), would be to always display a StageText as a >proxy bitmap when it's visible, and to show the StageText only when >typing text via the soft keyboard. > >It's hard for me to believe that the Adobe SDK team went into all the >pain of implementing the bitmap proxying, and the complex popup depth >calculations (cf.
