Layout Preferences

Use the fields in this section to specify the default size and placement of the IDL Development Environment's main window. (See Components of the IDLDE for descriptions of the components of the IDLDE.)

Select the Default Layout radio button to use the IDLDE's default layout, which depends on the size and resolution of your computer screen. If you select this radio button, all of the IDLDE's windows and toolbars will be displayed in their standard locations.

Select the Specify Layout radio button to manually specify the layout of the IDLDE:

Enter the number of pixels from the left-hand edge of the screen the IDLDE window should be displayed in the Left field

Enter the number of pixels from the top edge of the screen the IDLDE window should be displayed in the Top field

Enter the width of the IDLDE window in pixels in the Width field

Enter the height of the IDLDE window in pixels in the Height field

Note that if you select the Default Layout radio button after specifying values in these fields, your values will be replaced with "-1" to indicate that the default values will be used the next time IDL starts.

Select the windows and toolbars to be displayed from the Show Window section (Windows) or Windows and Control Panel sections (Motif)

Click Apply to apply your changes to the current IDLDE window without saving the values. (This allows you to use the Layout tab to control the appearance of the IDLDE for the current session without making your changes permanent.) Click OK to apply your changes and save the values; they will be used the next time IDL starts.

Select the Remember Layout radio button and click OK to save the current layout of the IDLDE windows for use the next time IDL starts. This options is useful if you have configured the windows manually and wish to save your changes.

Undocking IDLDE windows

Some of the elements of the IDLDE can be "undocked" from the interface and appear as separate, free-floating windows. On Microsoft Windows systems, use the mouse to select an element and drag it away from the main IDLDE window to undock the element. On UNIX systems, you can use the checkboxes in the Windows section to undock elements. For more information, see Docking/Undocking.
