Constructor Detail

DrawLayer.AbstractLayer

public DrawLayer.AbstractLayer(String name)

Deprecated. 

Construct new abstract layer with the known name and visibility.

Method Detail

getName

public String getName()

Deprecated. 

Description copied from interface: DrawLayer

Get the name of the layer. The layers that should work together over one component must have the different names.

Specified by:

getName in interface DrawLayer

---

extendsEOL

public boolean extendsEOL()

Deprecated. 

Description copied from interface: DrawLayer

Whether the layer wants to use the last context's background till the end of the window or not.

Specified by:

extendsEOL in interface DrawLayer

---

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

---

getNextActivityChangeOffset

public int getNextActivityChangeOffset(DrawContext ctx)

Deprecated. 

Description copied from interface: DrawLayer

Get the next position at which the activity of the layer will change. It can return Integer.MAX_VALUE to mark that the activity will never change or if it will change only by draw-marks. When this position will be reached the isActive will be called.

Specified by:

getNextActivityChangeOffset in interface DrawLayer

---

setNextActivityChangeOffset

public void setNextActivityChangeOffset(int nextActivityChangeOffset)

Deprecated. 

---

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

---

updateLineNumberContext

public int updateLineNumberContext(int lineNumber,
                                   DrawContext ctx)

Deprecated. 

Description copied from interface: DrawLayer

Update draw context related to the drawing of line number for the given line by setting colors, fonts and possibly other draw properties. The method can also change the current line number by returning the modified line-number than the original one. At the begining the first layer gets the line-number lineOffset + 1 but some layers can change it. If the layer doesn't want to change the line-number it should return the same value as it gets. The context can be affected to change the font and colors for the line-number. The context's getFragmentOffset() returns the begining of the line. The following methods in the context return undefined values: isEOL(), getBuffer(), getTokenID(), getTokenOffset(), getTokenLength(). The process of calling this method is independent of the status of the layers and is called for each layer even if it's not active.

Specified by:

updateLineNumberContext in interface DrawLayer

Parameters:

lineNumber - the number that will be drawn before the line's text. The layer can change it by returning a different value.

ctx - the draw context

---

toString

public String toString()

Deprecated. 

Overrides:

toString in class Object
