955959 - [Settings] [User Story] System font size setting

Status: RESOLVED WONTFIX

(Firefox OS Graveyard :: Gaia::Settings, enhancement)

Description

[Eagle Cui]

User Story:
As a user, I would like to configure system font size with some choices like small/normal/large/huge. When I select a font size, it should take effect to all the system apps (like settings, homescreen, dialer, message, browser etc.).

The mozbrowser API "zoom()" (see Bug 1044066) may be a reference to fulfill the user story. With this API the system app can simply zoom (and reflow) each app window according to the settings. We may also apply this feature to 3rd-party app since the system app is the only one who needs to react to the settings change. (Note that the UI within system app should be resized manually because you can't call mozbrowser API to an iframe itself. Otherwise, we may control it in "shell.js" via "mozContentEvent".)

By default, this API is associated to "fullZoom" value in "docshell" [1] which means the images will be resized as well when zooming. Since we'd prefer to change font size only, we may need to invent a similar API associated to "textZoom" value [2] instead.

For those who would like to take this bug: Due to the patch in bug 1044066 aims to v2.1 and we've moved mozbrowser API to webidl since v2.2, attachment #8552986 [details] [diff] [review] may be a better practice for v2.2 API implementation.

When we try using Commnet 2, the textZoom is more suitable than fullZoom.
When I checked, only fullZoom interface is added to master.
Could we add the textZoom API?

sounds good. Do you plan to land it to 2.2R?

The API can add. 
but the gaia also has a new set for large text because some structure is broken.
