Standard Controls

When you are working in the Screen Designer, the Screen Component Toolbox lists the standard and ActiveX controls available for use. If you are working with a graphical screen, all of the standard controls are available for you to use. If you are working with a character-based screen, those controls that are available only with graphical windows appear disabled in the Screen Component Toolbox. The sections that follow provide summary descriptions of each of the standard controls.

When you are working with ActiveX controls, the list of controls that appears in the ActiveX portion of the Screen Component Toolbox depends on which controls you have installed and registered. A detailed description of an ActiveX control can usually be found in the vendor documentation that accompanies it. More information about programming with ActiveX controls can be found in Working with Windows Technologies.

The size and location of most controls on a screen form can be changed. To change the size, click the control to select it, then drag a corner of the handle that appears. You can also use the keyboard shortcuts Shift+Arrow and Ctrl+Shift+Arrow to change the size of a control or window. To change a control’s location, click the control and drag it to the desired position on the screen form. You can also use the arrow keys or the Ctrl+Arrow keyboard shortcut to move items on the screen form. Note that status bar size and location cannot be changed. A status bar automatically grows and shrinks horizontally to match the width of the owning window.
