public class SplitterPanel

extends Panel

· Create a subcontainer that organizes container space within an Applet, Frame or Dialog container. This simplifies your component layout task.
· Hold other specialized Panel containers.

The SplitterPanel automatically recognizes the mouseDragged as the command to resize the appropriate subpanel boundary.

Subpanels can be resized at runtime by dragging panel borders with the mouse.

This code example splits a SplitterPanel into four subpanels and adds a button to two of the subpanels.

 splitterPanel1.split(splitterPanel1.SPLIT_HORIZONTAL);
 splitterPanel1.getTopPanel().split(splitterPanel1.SPLIT_VERTICAL);
 splitterPanel1.getBottomPanel().split(splitterPanel1.SPLIT_VERTICAL);
 // add a button to the top left panel
 splitterPanel1.getTopLeftPanel().add(new Button("Top Left"));
 // add a button to the lower right panel
 splitterPanel1.getBottomRightPanel().add(new Button("Bottom Right"));

Clearing this introduces a clipping effect, rather than a scaling effect.

Returns:

the first new SplitterPanel if successful (left or top)

See Also:

SPLIT_VER, SPLIT_HOR

Splits a SplitterPanel into two panels and adds two components. This creates two new SplitterPanels which are nested within the original SplitterPanel.

If the split type is SPLIT_VER the new panels are arranged side-by-side with a splitter bar vertically between them. Component theComp1 would be placed in the left panel, theComp2 in the right.

If the split type is SPLIT_HOR the new panels are arranged one above the other with a splitter bar horizontally between them. Component theComp1 would be placed in the top panel, theComp2 in the bottom.

Parameters:

splitType - SPLIT_VER or SPLIT_HOR to request vertical or horizontal splits

theComp1 - the first component (left or top)

theComp2 - the second component (right or bottom)

public void update(Graphics g)

Handles redrawing of this component on the screen. This is a standard Java AWT method which gets called by the Java AWT (repaint()) to handle repainting this component on the screen.

Typically this method paints the background color to clear the component's drawing space, sets graphics context to be the foreground color, and then calls paint() to draw the component. It is overridden here to reduce flicker by eliminating the unnecessary clearing of the background.

Parameters:

g - the graphics context

Overrides:

update in class Container
