public class SplitDock
extends javax.swing.JPanel
implements CompositeDock

This is a composite dock that can contain zero, one, or two child docks. It can not contain dockables. When dockables are added, child docks are created, and the dockables are added to the child docks.

Information on using split docks is in How to Use Composite Docks in The Sanaware Developer Guide.

When there is only one child dock, this dock is located in the center of this dock. When there are 2 child docks, there is one at the top and one at the bottom, or there is one at the left and one at the right. The child docks are put in a split pane created with the component factory of the docking manager DockingManager.getComponentFactory() with the method SwComponentFactory.createJSplitPane().

The positions for child docks of this dock are one-dimensional. The possible child docks and their first position values are:

A dockable can only be added if it has as one of its docking modes:

It can only be added in a position that corresponds with one of its docking modes.

If the mouse is inside a priority rectangle, the dockable can be docked with priority (see Priority.CAN_DOCK_WITH_PRIORITY). When the mouse is inside the panel of this dock, but outside the priority rectangles, the dockable can be docked, but without priority (see Priority.CAN_DOCK). When the dock is empty, the only priority rectangle is in the middle of the dock. When there is already a child dock, there are 4 priority rectangles at the 4 borders of the panel of this dock.

When this dock contains no child docks, it is empty. When this dock contains two child docks, it is full.

When this dock is empty, and a first dockable is added, a child dock is created with the factory retrieved by getChildDockFactory(). The dockable is added to the child dock. The child dock is put in the center of this panel.

When there is already one child dock in the center, and a new dockable is added, again a child dock is created with the factory retrieved by getChildDockFactory(). The dockable is added to the child dock. But now for both child docks a split dock is created with the factory retrieved by getCompositeChildDockFactory(). The child docks are added to these new docks, and these new docks are put at the left and the right side of the split of the split pane. These new docks are now the child docks of this split dock.

Method Detail

getDockPriority

public int getDockPriority(Dockable dockable,
                           java.awt.Point relativeLocation)

Determines if the dockable can be added.

The dockable can be added, if:

There are also some optimizations done. We want to prevent that dockables are removed from this dock and added to this dock again at the same position. In that case Priority.CANNOT_DOCK is returned.

Specified by:
getDockPriority in interface Dock
Parameters:
dockable - The dockable that will be added.
relativeLocation - The location where the dockable will be added.
Returns:
The integer that determines the priority for adding the dockable. If the dockable cannot be added, CANNOT_DOCK is returned. The higher the integer, the higher the priority for docking the dockable in this dock.

retrieveDockingRectangle

                                    java.awt.Rectangle rectangle)
Description copied from interface: Dock

Sets the given rectangle to the position and size of the graphical content component of the dockable, when it will be docked in this dock.

Determines if the dockable can be added to this dock. If the dockable cannot be added, it returns Priority.CANNOT_DOCK and the given rectangle is not changed.

Specified by:
retrieveDockingRectangle in interface Dock
Parameters:
dockable - The dockable that will be added.
relativeLocation - The location where the dockable will be added.
dockableOffset - The mouse location where the dragging started, relatively to the previous dock of the dockable.
rectangle - This rectangle will be set to the location and size of the graphical component of the dockable when it will be docked in this dock. The rectangle is relative to this dock.
Returns:
If the dockable cannot be added, Priority.CANNOT_DOCK is returned, otherwise a positive integer.
