Script Editor

Each CygNet screen has an associated Script Mode. In this mode, the graphical screen editor is not visible and the Script Editor is displayed in its place. To toggle script mode, do one of the following:

Click the icon in the Layout toolbar.
Choose Show Script Editor from the View menu.
Double-click an object on the screen in Edit mode.
Press Ctrl+T in Edit mode.

Note: Script mode will not exit if the script contains a syntax error. If this is the case, the cursor will move to the line on which the error occurs.

The layout of the Script Editor dialog box is described below.

Controls

Description

Script View Buttons

	Toggle on/off Script Editor
	Event View — Show only the selected event in the window.
	Object View — Show all code related to the selected object.
	Full Module View — Show all code related to all objects.

Object Drop-Down Menu

Event Drop-Down Menu

Breakpoint/Bookmark Pane

Shows breakpoints and bookmarks next to lines of code. Left click next to a line of code to toggle a breakpoint or right-click to toggle a bookmark.

The script editor provides auto completion ("IntelliSense"), so that typing a recognized object will cause the object’s properties and methods to appear in a list box. When one of the items is selected, its data type or parameter data types will be displayed as an aid.

The code window distinguishes user code, comments, and keywords with different colors. Comments are green, keywords are blue, literal values are pink, and all other text is black.

With the script editor, you can toggle the view to show the scripts for a specific event for a specific object (Event view), all of the events for a specific object (Object view), or all of the events for all of the screen’s objects (Full Module view).

To get back to Edit mode to work with objects, click one of the Script mode toggle buttons Script Mode button . Do not close the script editor using the "X" in the title bar. This will close the screen file (see Modes of Operation for a description of how modes relate to one another). When you close the script editor, a syntax check is run to make sure that the new code you entered is valid. If an error is encountered, the editor will not close. See Syntax Errors for more information.

The script editor provides additional functionality through its context menu and the buttons in the Layout bar.
