Documentation

data VtyWidgetCtx t Source #

The context within which a VtyWidget runs

Constructors

VtyWidgetCtx

Fields

_vtyWidgetCtx_width :: Dynamic t Int
The width of the region allocated to the widget.
_vtyWidgetCtx_height :: Dynamic t Int
The height of the region allocated to the widget.
_vtyWidgetCtx_focus :: Dynamic t Bool
Whether the widget should behave as if it has focus for keyboard input.
_vtyWidgetCtx_input :: Event t VtyEvent
User input events that the widget's parent chooses to share. These will generally be filtered for relevance: * Keyboard inputs are restricted to focused widgets * Mouse inputs are restricted to the region in which the widget resides and are translated into its internal coordinates.
