Constructor Summary | |
---|---|
ComponentView(Element elem)
Creates a new ComponentView object. |
Method Summary | |
---|---|
protected Component |
createComponent()
Create the component that is associated with this view. |
float |
getAlignment(int axis)
Determines the desired alignment for this view along an axis. |
Component |
getComponent()
Fetch the component associated with the view. |
float |
getMaximumSpan(int axis)
Determines the maximum span for this view along an axis. |
float |
getMinimumSpan(int axis)
Determines the minimum span for this view along an axis. |
float |
getPreferredSpan(int axis)
Determines the preferred span for this view along an axis. |
Shape |
modelToView(int pos,
Shape a,
Position.Bias b)
Provides a mapping from the coordinate space of the model to that of the view. |
void |
paint(Graphics g,
Shape a)
The real paint behavior occurs naturally from the association that the component has with its parent container (the same container hosting this view). |
void |
setParent(View p)
Sets the parent for a child view. |
int |
viewToModel(float x,
float y,
Shape a,
Position.Bias[] bias)
Provides a mapping from the view coordinate space to the logical coordinate space of the model. |

If the parent view parameter is null, this view is being
cleaned up, thus the component is removed from its parent.
The changing of the component hierarchy will touch the component lock, which is the one thing that is not safe from the View hierarchy. Therefore, this functionality is executed immediately if on the event thread, or is queued on the event queue if called from another thread (notification of change from an asynchronous update).
