The Toolbox on the right side of the screen contains icons of all the controls you can place in a dialog.
Summary: Add a push button.
To add your first control to the dialog, click the push button icon in the Toolbox, move the mouse pointer into the dialog, and click a second time.
| The new push button is now selected, and the Properties Bar now displays information about the button instead of the dialog (see Figure 1.3). Note that the button can be resized by grabbing its resize handles with the mouse, and it can be moved with the cursor keys or by dragging it with the mouse. |
