bluej.editor.moe.BlueJSyntaxView
All known Subclasses: bluej.editor.moe.MoeSyntaxView,
| BlueJSyntaxView | | abstract public class BlueJSyntaxView extends PlainView (Code) | | A Swing view implementation that colorizes lines of a
SyntaxDocument using a TokenMarker.
This class should not be used directly; a SyntaxEditorKit
should be used instead.

| Method Summary | |
| protected void | drawLine(int lineIndex, Graphics g, int x, int y)
Paints the specified line. | | protected void | drawLineNumber(Graphics g, int lineNumber, int x, int y)
| | protected Color | getDefaultColor()
| | final protected boolean | hasTag(Element line, String tag)
Check whether a given line is tagged with a given tag. | | public Rectangle | lineToRect(Shape a, int line)
| | public Shape | modelToView(int pos, Shape a, Position.Bias b)
Provides a mapping from the document model coordinate space
to the coordinate space of the view mapped to it. | | public float | nextTabStop(float x, int tabOffset)
Returns the next tab stop position after a given reference position.
This implementation does not support things like centering so it
ignores the tabOffset argument.
Parameters:
x - the current position >= 0
Parameters:
tabOffset - the position within the text streamthat the tab occurred at >= 0. | | protected void | paintSyntaxLine(Segment line, int lineIndex, int x, int y, Graphics g, SyntaxDocument document, TokenMarker tokenMarker, Color def)
paints a line with syntax highlighting,
redefined from DefaultSyntaxDocument. | | abstract public void | paintTaggedLine(Segment line, int lineIndex, Graphics g, int x, int y, SyntaxDocument document, TokenMarker tokenMarker, Color def, Element lineElement)
Draw a line for this view, including the tag mark. | | public int | viewToModel(float fx, float fy, Shape a, Position.Bias[] bias)
Provides a mapping from the view coordinate space to the logical
coordinate space of the model. |
| BREAKPOINT_OFFSET | | final protected static int BREAKPOINT_OFFSET(Code) | | |
| TAG_WIDTH | | final public static short TAG_WIDTH(Code) | | width of tag area for setting breakpoints
|
| BlueJSyntaxView | | public BlueJSyntaxView(Element elem)(Code) | | Creates a new BlueJSyntaxView.
Parameters:
elem - The element |
| drawLine | | protected void drawLine(int lineIndex, Graphics g, int x, int y)(Code) | | Paints the specified line.
This method performs the following:
- Gets the token marker and color table from the current document,
typecast to a SyntaxDocument.
- Tokenizes the required line by calling the
markTokens() method of the token marker.
- Paints each token, obtaining the color by looking up the
the Token.id value in the color table.
If either the document doesn't implement
SyntaxDocument, or if the returned token marker is
null, the line will be painted with no colorization.
Currently, we assume that the whole document uses the same font.
To support font changes, some of the code from "initilise" needs
to be here to be done repeatedly for each line.
Parameters:
lineIndex - The line number
Parameters:
g - The graphics context
Parameters:
x - The x co-ordinate where the line should be painted
Parameters:
y - The y co-ordinate where the line should be painted |
| drawLineNumber | | protected void drawLineNumber(Graphics g, int lineNumber, int x, int y)(Code) | | Draw the line number in front of the line
|
| getDefaultColor | | protected Color getDefaultColor()(Code) | | Return default foreground colour
|
| hasTag | | final protected boolean hasTag(Element line, String tag)(Code) | | Check whether a given line is tagged with a given tag.
Parameters:
line - The line to check
Parameters:
tag - The name of the tag True, if the tag is set |
| lineToRect | | public Rectangle lineToRect(Shape a, int line)(Code) | | redefined from PlainView private method to allow for redefinition of
modelToView method
|
| modelToView | | public Shape modelToView(int pos, Shape a, Position.Bias b) throws BadLocationException(Code) | | Provides a mapping from the document model coordinate space
to the coordinate space of the view mapped to it. This is a
redefined method from PlainView that adds an offset for the
view to allow for a breakpoint area in the associated editor.
Parameters:
pos - the position to convert >= 0
Parameters:
a - the allocated region to render into the bounding box of the given position
exception:
BadLocationException - if the given position does notrepresent a valid location in the associated document

| nextTabStop | | public float nextTabStop(float x, int tabOffset)(Code) | | Returns the next tab stop position after a given reference position.
This implementation does not support things like centering so it
ignores the tabOffset argument.
Parameters:
x - the current position >= 0
Parameters:
tabOffset - the position within the text streamthat the tab occurred at >= 0. the tab stop, measured in points >= 0 |
| viewToModel | | public int viewToModel(float fx, float fy, Shape a, Position.Bias[] bias)(Code) | | Provides a mapping from the view coordinate space to the logical
coordinate space of the model.
Parameters:
fx - the X coordinate >= 0
Parameters:
fy - the Y coordinate >= 0
Parameters:
a - the allocated region to render into the location within the model that best represents thegiven point in the view >= 0
