Methods

Overloaded methods

activate

gutterRendererActivate

Arguments

:: (HasCallStack, MonadIO m, IsGutterRenderer a)

=> a

renderer: a GutterRenderer

-> TextIter

iter: a TextIter at the start of the line where the renderer is activated

-> Rectangle

area: a Rectangle of the cell area where the renderer is activated

-> Event

event: the event that triggered the activation

-> m ()

Emits the activate signal of the renderer. This is called from Gutter and should never have to be called manually.

begin

gutterRendererBegin

Arguments

:: (HasCallStack, MonadIO m, IsGutterRenderer a)

=> a

renderer: a GutterRenderer

-> Context

cr: a Context

-> Rectangle

backgroundArea: a Rectangle

-> Rectangle

cellArea: a Rectangle

-> TextIter

start: a TextIter

-> TextIter

end: a TextIter

-> m ()

Called when drawing a region begins. The region to be drawn is indicated by start and end. The purpose is to allow the implementation to precompute some state before the draw method is called for each cell.

draw

gutterRendererDraw

Arguments

:: (HasCallStack, MonadIO m, IsGutterRenderer a)

=> a

renderer: a GutterRenderer

-> Context

cr: the cairo render context

-> Rectangle

backgroundArea: a Rectangle indicating the total area to be drawn

-> Rectangle

cellArea: a Rectangle indicating the area to draw content

-> TextIter

start: a TextIter

-> TextIter

end: a TextIter

-> [GutterRendererState]

state: a GutterRendererState

-> m ()

Main renderering method. Implementations should implement this method to draw onto the cairo context. The backgroundArea indicates the total area of the cell to be drawn. The cellArea indicates the area where content can be drawn (text, images, etc).

The backgroundArea is the cellArea plus the padding on each side (two times the GutterRenderer:xpad horizontally and two times the GutterRenderer:ypad vertically, so that the cellArea is centered inside backgroundArea).

The state argument indicates the current state of the renderer and should be taken into account to properly draw the different possible states (cursor, prelit, selected) if appropriate.
