    • Field Detail

      • translate

        protected java.awt.Point 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 Detail

      • getTranslate

        public java.awt.Point getTranslate()
        Returns the translate.

      • setTranslate

        public void setTranslate​(java.awt.Point value)
        Sets the translate.

      • scrollRectToVisible

        public void scrollRectToVisible​(java.awt.Rectangle aRect,
                                boolean extend)
        Overrides parent method to add extend flag for making the control larger during previews.

      • extendComponent

        protected void extendComponent​(java.awt.Rectangle rect)
        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

        public java.lang.String getToolTipText​(java.awt.event.MouseEvent e)
        Overrides:
        getToolTipText in class javax.swing.JComponent

      • 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

        public void paint​(java.awt.Graphics g)
        Overrides:
        paint in class javax.swing.JComponent

        Overrides:
        paintComponent in class javax.swing.JComponent

      • drawGraph

                      boolean drawLabels)

      • drawFromRootCell

        protected void drawFromRootCell()
        Hook to draw the root cell into the canvas.

      • getExtendedCellBounds

        protected java.awt.Rectangle getExtendedCellBounds​(mxCellState state)
        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

        public void drawCell​(mxICanvas canvas,
                     java.lang.Object cell)
        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.

        Draws the child edges and/or all other children in the given cell depending on the boolean arguments.

      • isCellDisplayable

        protected boolean isCellDisplayable​(java.lang.Object cell)
        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.
