The Resizer is a resizable container widget.

• Configurable whether all four edges are resizable or only the right and bottom edge
• Live resize or resizing using a resize frame (like in the screen shot)
• Sensitivity configurable i.e. The number of pixels on each side of a resize edge, where the resize cursor is shown.

The Resizer is a generic container just like a Composite, which can be resized by using the mouse. Either all edges or only the right and bottom edge can be configured to be resizable.

Here are some links that demonstrate the usage of the widget:
