class ScrollableImageCanvas

extends java.awt.Canvas

implements java.awt.event.MouseListener, java.awt.event.MouseMotionListener

This class supports a scrollable image canvas for the pseudoarray image. The scrollbars live in ArrayScroller whose event handler calls the ScrollableImageCanvas. In additionl, the mouse event handler finds the current gene if the xy coords are close to any gene and then invokes updates of other windows through the PopupRegistry.

mousePressed

public void mousePressed(java.awt.event.MouseEvent e)

Parameters:

e - is MouseEvent so can get modifiers and (x,y) event data

mouseReleased

public void mouseReleased(java.awt.event.MouseEvent e)

mouseReleased() - process mouse events for pseudoarray image. It attempts to match the (x,y) position to active regions to change the current HP-X or HP-Y sample (also toggling the [X] and [Y]). If is is successful, it redraws the Pseudoarray Image and reruns the data Filter.

Otherwise, it attempts to latch onto a spot's (x,y) (+-spotRadius) to redefine the current gene. If it matches a spot, it redefines the current gene, updates gene information in status lines, runs the data filter, updates (xImg,yImg) with the relative position in canvas by adding (x,y) to paint ULHC base address (xBase,yBase) and repaints the canvas.

Specified by:

mouseReleased in interface java.awt.event.MouseListener

                          int markerBits)

drawGeneList() - draw a gene list on either SaveAsGif or Pseudoarray Image. The marker bits determine what to draw.
If MARKER_GENES is set, then draw each spot in the gene list in Red(white) MARKER_PLUS, MARKER_CIRCLE or MARKER_SQUARE, MARKER_KMEANS_CLUSTER, or NONE if 0 or MARKER_NONE.
If using PLOT_PSEUDO_F1F2_IMAGE || PLOT_PSEUDO_HP_XY_IMAGE then draw it in white since the background is black.
If the MARKER_CURRENT is set then draw it as a Green circle. if Gang mode is enabled, draw it on both spots.

Parameters:

g - is graphics context

ml - is the gene list to use for overlay graphics

markerBits - is the MARKER_xxxx symbol(s) to use

drawGeneClustersOfCurrentGene

private void drawGeneClustersOfCurrentGene(java.awt.Graphics g)

drawGeneClustersOfCurrentGene() - draw genes in clusters as colored circles or squares

drawCircleAroundSpot(java.awt.Point, java.awt.Graphics, java.awt.Color, int, int), drawSquareAroundSpot(java.awt.Point, java.awt.Graphics, java.awt.Color, int)

drawCountsOfGeneClusters

private void drawCountsOfGeneClusters(java.awt.Graphics g)

drawCountsOfGeneClusters() - draw colored circles as nGeneClusterCnt's. If the Filter count has changed, then re-run the clustering of all filtered genes. This draws circles proportional to # clusters/gene

Parameters:

g - is graphics context

drawNprimaryNodesGenes

private boolean drawNprimaryNodesGenes(java.awt.Graphics g)

drawNprimaryNodesGenes() - draw magenta circles as nGeneClusterCnt's. This draws circles proportional to the K-means # clusters/Node-gene.

Parameters:

g - is graphics context

Returns:

true if succeed.

drawEditedGeneList

private void drawEditedGeneList(java.awt.Graphics g)

drawEditedGeneList() - draw magenta squares of Filter.editedCL genes

Parameters:

g - is graphics context

EditedGeneList, Filter, drawSquareAroundSpot(java.awt.Point, java.awt.Graphics, java.awt.Color, int)

paint

public void paint(java.awt.Graphics g)

paint() - repaint scrollable canvas in region defined by the scroll bars. This includes the pseudoarray image which is then followed by various overlays include: the genes passing the data filter, clustered genes, K-means clustered genes, genes in the EGL, etc. If they requested a "SaveAs GIF", then it creates WriteGifEncoder image to draw in and then save and then it repaints one more time to refresh the visible canvas.

Overrides:

paint in class java.awt.Canvas

Parameters:

g - is graphics context
