adjustAllocation
protected Shape adjustAllocation(Shape shape)
Vertically centers the single line of text within the
bounds of the input shape. The returned Rectangle is centered
vertically within shape and has a height of the
preferred span along the Y axis. Horizontal adjustment is done according
to the horizontalAligment property of the component that is rendered.
shape - the shape within which the line is beeing centered
getPreferredSpan
public float getPreferredSpan(int axis)
Returns the preferred span along the specified axis. Normally the view is
rendered with the span returned here if that is possible.
- getPreferredSpan in interface PlainView
- the preferred span along the specified axis
getResizeWeight
public int getResizeWeight(int axis)
Returns the resize weight of this view. A value of 0 or less
means this view is not resizeable. Positive values make the view
resizeable. The default implementation returns 0
unconditionally.
- getResizeWeight in interface View
- the resizability of this view along the specified axis
modelToView
public Shape modelToView(int pos,
Shape a,
Position.Bias bias)
throws BadLocationException Maps a position in the document into the coordinate space of the View.
The output rectangle usually reflects the font height but has a width
of zero.
- modelToView in interface PlainView
pos - the position of the character in the modela - the area that is occupied by the view
- a rectangle that gives the location of the document position
inside the view coordinate space
viewToModel
public int viewToModel(float fx,
float fy,
Shape a,
Position.Bias[] bias) Maps coordinates from the View's space into a position
in the document model.
- viewToModel in interface PlainView
a - the allocation of this View
- the position in the document that corresponds to the screen
coordinates
x, y
