HitInfo	hitTest(PEMouseEvent e) This implementation calls super.hitTest and returns the result if non-null (this should be a HitInfo.Point), then returns a HitInfo.Interior if the mouse-click occured inside the text bound (as defined by text layout)

Constructor Detail

TextViewHybrid

public TextViewHybrid(PicText te)

construct a new View for the given PicRectangle

Method Detail

getRotation

protected double getRotation()

Returns the text rotation in radians : subclassers that don't support rotating text may return 0 here. Used by TextLayout only.

changedUpdate

public void changedUpdate(DrawingEvent.EventType eventType)

Give notification from the model that a change occured to the text this view is responsible for rendering.

Specified by:

changedUpdate in interface View

Overrides:

changedUpdate in class DefaultViewFactory.LeafElementView

run

public void run()

Specified by:

run in interface java.lang.Runnable

syncStringLocation

protected void syncStringLocation()

update strx stry = location of TextLayout's bottom-Left corner with respect to PicText's anchor-point

syncShape

protected void syncShape()

Synchronize the textLayout and the shape (=frame box, by calling syncFrame) with the model When TextLayout is used, this delegates to getRotation() where computing rotation angle is concerned, and updates the AffineTransform returned by getTextToModelTransform().

Overrides:

syncShape in class DefaultViewFactory.LeafElementView

syncFrame

protected void syncFrame()

synchronize frame shape and location (TextLayout only) ; this is called by syncShape(), so that subclasser might override easily when only rectangular shapes are availables.

getDimensionsFromLogFile

protected void getDimensionsFromLogFile(java.io.BufferedReader reader,
                                        PicText text)

syncBounds

protected void syncBounds()

Synchronizes bounding box with the model ;

Overrides:

syncBounds in class DefaultViewFactory.LeafElementView

paint

public void paint(java.awt.Graphics2D g,
                  java.awt.geom.Rectangle2D a)

Render the View to the given graphic context. This implementation render the interior first, then the outline.

Specified by:

paint in interface View

Overrides:

paint in class DefaultViewFactory.LeafElementView

a - the current graphic clip

hitTest

public HitInfo hitTest(PEMouseEvent e)

This implementation calls super.hitTest and returns the result if non-null (this should be a HitInfo.Point), then returns a HitInfo.Interior if the mouse-click occured inside the text bound (as defined by text layout)

Overrides:

hitTest in class DefaultViewFactory.LeafElementView

Returns:

a HitInfo corresponding to the given mouse-event

getTextLayout

public java.awt.font.TextLayout getTextLayout()

[SR:pending] make this view implement aka TextEditableView interface (or something like it), where TextEditableView is a subinterface of View with text-editing specific capabilities. Returns the TextLayout which is responsible for painting the textual content of this element

getTextToModelTransform

public java.awt.geom.AffineTransform getTextToModelTransform()

Return an affine transform which translat b/w the TextLayout coordinate system and the jpicedt.graphic.model coordinate system. [SR:pending] refactor method name to something more explanatory
