A composing text is a range of text that you are currently working on. While it is in the composition state, it can be freely changed, these changes are considered as a batch operation, and are submitted as one update at the end of the composition, so the whole text modification is stored as one action in the edit history. | A composing text is a range of text that you are currently working on.

GeckoInputConnection tracks the composing state using mComposing flag. When it receives a text modification request from Android it sets this flag and sends IME_COMPOSITION_BEGIN event to Gecko. While in that state the mComposingText variable contains the current composing text, and mCompositionStart points to a start index of the composition within the text body. mCompositionSelStart/mCompositionSelLen track the text selection during the composition, as Gecko selection is not supposed to change while in the composing state. | |||
