Field Detail

bounds

protected java.awt.Rectangle bounds

Node bounds, relative to the bottom left corner of the tree.

drawPoint

protected java.awt.Point drawPoint

Point at which the next component should be drawn. Nodes are drawn left to right, and the draw point is updated as parts of the node are rendered. For example, the toggle triangle is drawn first at the draw point, and then the draw point is moved to the right by the width of the triangle, so the next component will draw at the correct point. The draw point is reset to the lower left corner of the node bounds before each render cycle.

node

protected TreeNode node

Node that this layout applies to.

numLines

protected int numLines

Number of lines of wrapped description text in this layout.

pickBounds

protected java.awt.Rectangle pickBounds

pickScreenBounds

protected java.awt.Rectangle pickScreenBounds

screenBounds

protected java.awt.Rectangle screenBounds

Node bounds relative to the bottom left corner of the viewport. This field is set by reset(java.awt.Point).

textWrapWidth

protected int textWrapWidth

The width used to wrap the description text.

wrappedText

protected java.lang.String wrappedText

Wrapped version of the node description text. Computed once and then cached here.
