Deprecated. 

Method Detail

extendsEmptyLine

public boolean extendsEmptyLine()

Deprecated. 

Description copied from interface: DrawLayer

Whether the layer marks the empty line with the background by half of the character.

Specified by:

extendsEmptyLine in interface DrawLayer

Overrides:

extendsEmptyLine in class DrawLayer.AbstractLayer

---

init

public void init(DrawContext ctx)

Deprecated. 

Description copied from interface: DrawLayer

Called each time the paint begins for all layers in the layer chain regardless whether they are currently active or not. It is intended to prepare the layer. It doesn't need to set the next-activity-change-offset because isActive() will be called at the begining of the drawing when this method finishes.

Specified by:

init in interface DrawLayer

Overrides:

init in class DrawLayer.AbstractLayer

---

isActive

public boolean isActive(DrawContext ctx,
                        MarkFactory.DrawMark mark)

Deprecated. 

Description copied from interface: DrawLayer

Return whether the layer is active or not. This method is called at the begining of the drawing, then each time when the draw-mark is found at the current fragment offset or when drawing reaches the next-activity-change-offset of this layer (mark parameter is null in this case). The layer must return whether it wants to be active for the next drawing or not. The layer should also consider changing the next-activity-change-offset because the draw-engine will ask for it after this method finishes. If the mark is found at the same position like next-activity-change-offset is, then this method is called only once with the valid mark parameter.

Parameters:

ctx - current context with the information about the drawing

mark - draw-mark at the fragment-offset or null if called because of the next-activity-change-offset.

---

updateContext

public void updateContext(DrawContext ctx)

Deprecated. 

Description copied from interface: DrawLayer

Update draw context by setting colors, fonts and possibly other draw properties. The method can use information from the context to find where the painting process is currently located. It is called only if the layer is active.
