modelSource

RichTextModel? model

Backing data model of text document.

modifySource

override Void modify(Int start, Int replaceLen, Str newText)

Overrides fwt::TextWidget.modify

Convenience for RichTextModel.modify.

offsetAtPosSource

native Int? offsetAtPos(Int x, Int y)

Map a coordinate on the widget to an offset in the text, or return null if no mapping at specified point.

onCaretSource

readonly EventListeners onCaret := EventListeners()

Callback when the caret position is modified.

Event id fired:

• EventId.caret

Event fields:

• Event.offset: the new caret offset

onModelModifySource

internal native Void onModelModify(Event event)

onModelModifyFuncSource

private |Event| onModelModifyFunc := &this.onModelModify()

onModifySource

readonly EventListeners onModify := EventListeners()

Callback when the text is modified. This event occurs after the modification. See onVerify to trap changes before they occur.

Event id fired:

• EventId.modified

Event fields:

• Event.data: the TextChange instance.

onSelectSource

readonly EventListeners onSelect := EventListeners()

Callback when the selection is modified.

Event id fired:

• EventId.select

Event fields:

• Event.offset: the starting offset
• Event.size: the number of chars selected

onVerifySource

readonly EventListeners onVerify := EventListeners()

Callback before the text is modified. This gives listeners a chance to intercept modifications and potentially modify the inserted text. This event occurs before the modification. See onModify to trap changes after they occur.

Event id fired:

• EventId.verify

Event fields:

• Event.data: a TextChange instance where newText specifies the proposed text being inserted. The callback can update newText with the actual text to be inserted or set to null to cancel the modification.

onVerifyKeySource

readonly EventListeners onVerifyKey := EventListeners()

Callback before a key event is processed. This gives listeners a chance to trap the key event and consume it before it is processed by the editor.

Event id fired:

• EventId.verifyKey

Event fields:

• Event.keyChar: unicode character represented by key event
• Event.key: key code including the modifiers

repaintLineSource

Void repaintLine(Int lineIndex)

Repaint the line specified by the zero based line index.

repaintRangeSource

native Void repaintRange(Int offset, Int len)

Repaint the specified text range.

showLineSource

native Void showLine(Int lineIndex)

Ensure the editor is scrolled such that the specified line is visible.

tabSpacingSource

native Int tabSpacing

Tab width measured in space characters. Default is 2.

override Str text

Overrides fwt::TextWidget.text

Convenience for model.text (model must be installed).
