NanoUI.Widgets.TextField
Description
Commands run on a text field from outside its frame: an app's Edit menu, a toolbar button, the field's own context menu.

Documentation
runTextCommand :: forall (es :: [Effect]). Ui :> es => WidgetId -> TextCommand -> Eff es () Source #
Run a command on the text field (text input, search field, text area)
with this id, as if its keys were pressed: runTextCommand (respId resp)
Undo. The field takes keyboard focus, and its next frame returns the
changed text and a respChanged pulse. An id that is not a text
field is ignored.
textCanUndo :: forall (es :: [Effect]). Ui :> es => WidgetId -> Eff es Bool Source #
Whether Undo would change the field, for
enabling a menu item.
textCanRedo :: forall (es :: [Effect]). Ui :> es => WidgetId -> Eff es Bool Source #
Whether Redo would change the field, for
enabling a menu item.
applyTextFieldCommand :: Context -> WidgetId -> TextCommand -> IO () Source #
Run a command on the field with this id and focus it: the command comes from a menu or button that may not be over the field, and the caret, selection highlight and next keystroke belong to the field it edited.
textFieldMode :: Context -> WidgetId -> IO (Maybe EditorMode) Source #
How the field with this id edits: from its node when it has one this frame, or from what it recorded the last time it was declared.
textFieldHistory :: Context -> WidgetId -> IO EditHistory Source #
The undo history of the field with this id, empty when it has none.
