LineNumberMargin

public LineNumberMargin(CodeEditor editor)

Method Detail

paintLineMargin

public void paintLineMargin(Graphics g,
                            Rectangle rect,
                            int line)

Description copied from class: AbstractLineMargin

Paint line margin.

Specified by:

paintLineMargin in class AbstractLineMargin

Parameters:

g - the Graphics instance

rect - the rectangle to paint the line margin

line - the view line index to be painted

getPreferredWidth

public int getPreferredWidth()

Description copied from interface: Margin

Gets the preferred width of the margin. Since the margin is placed vertical besides the code editor, the height is fixed. That's why it only needs to ask for the preferred width using this method.

Returns:

the preferred width.

getToolTipText

public String getToolTipText(int line)

Description copied from class: AbstractLineMargin

Gets the tool tip text from the view line index.

Specified by:

getToolTipText in class AbstractLineMargin

Parameters:

line - the view line index

Returns:

the tool tip text.

isShowTooltip

public boolean isShowTooltip()

Gets the flag indicating if tooltip should be displayed.

Returns:

true if tooltip should be displayed. Otherwise false.

See Also:

setShowTooltip(boolean)

setShowTooltip

public void setShowTooltip(boolean showTooltip)

Sets the flag indicating if tooltip should be displayed.

By default, the value is true to keep original behavior.

Parameters:

showTooltip - the flag

createModelChangedCallback

protected MarginSupport.ModelChangedCallback createModelChangedCallback()

Description copied from class: AbstractMargin

Creates the ModelChangedCallback. It will be called when the model is changed. The default implementation returns null. Subclass can override it to return a valid callback.

Overrides:

createModelChangedCallback in class AbstractMargin

Returns:

the ModelChangedCallback.
