translate
Specifies a translation for painting. This should only be used during mouse drags and must be reset after any interactive repaints. Default is (0,0). This should not be null.

Method Details
-
getTranslate
Returns the translate. -
setTranslate
Sets the translate. -
getGraphContainer
-
scrollRectToVisible
Overrides parent method to add extend flag for making the control larger during previews. -
extendComponent
Implements extension of the component in all directions. For extension below the origin (into negative space) the translate will temporaly be used and reset with the next mouse released event. -
getToolTipText
- Overrides:
getToolTipText
in classJComponent
-
updatePreferredSize
public void updatePreferredSize()Updates the preferred size for the given scale if the page size should be preferred or the page is visible. -
paint
- Overrides:

paintComponent
- Overrides:

drawGraph
-
drawFromRootCell
protected void drawFromRootCell()Hook to draw the root cell into the canvas. -
hitClip
-
getExtendedCellBounds
- Parameters:
state
- the cached state of the cell whose extended bounds are to be calculated- Returns:
- the bounds of the cell, including the label and shadow and allowing for rotation
-
drawCell
Draws the given cell onto the specified canvas. This is a modified version of mxGraph.drawCell which paints the label only if the corresponding cell is not being edited and invokes the cellDrawn hook after all descendants have been painted.- Parameters:
canvas
- Canvas onto which the cell should be drawn.cell
- Cell that should be drawn onto the canvas.
-
drawChildren
Draws the child edges and/or all other children in the given cell depending on the boolean arguments. -
cellDrawn
-
isCellDisplayable
Returns true if the given cell is not the current root or the root in the model. This can be overridden to not render certain cells in the graph display.
