Drawing a component on the design form involves three steps.
Step 1 : Select The Component
The first stage is to select the component you want to draw from the toolbox
of availible components. This will result in the button for that component
staying depressed indicating that component is selected.
Step 2 : Draw The Component
To add the component to the design form, click and drag out the shape of the component on the form. It is important to select and component with single clicks in the same way as other buttons work, then to click and drag on the design form. While you are dragging the component shape, it will remain in a rubber band drawing state.
Step 3 : Finishing The Component
When the required shape is achieved, let go of the mouse button and the component will be added to the design form and, depending on the layout manager in use, may be snapped to slign with the grid.
