CodeInsight page (Editor Options dialog box)

Use the CodeInsight page of the Editor Options dialog box to configure CodeInsight.

To open the CodeInsight page, choose Tools|Editor Options, then click the CodeInsight tab.

JBuilder's CodeInsight displays context-sensitive pop-up windows within the editor that list:

Important: The project must be compiled for imported classes to be available to CodeInsight.

If the options on this page are selected, the popup windows display after you enter the required activation characters (detailed below) on the keyboard and pause for the delay specified in the Delay slider bar.

If the options on this page are not selected, CodeInsight is available on demand by pressing shortcut keys.

To view or customize the CodeInsight keystrokes, choose Tools|Editor Options and choose the Customize button on the Editor page to open the Keymap Editor. The Keymap Editor is read-only in JBuilder Personal.

General

Show Error Messages

If this option is on and the MemberInsight or ParameterInsight pop-up cannot be displayed due to compiler errors, CodeInsight expands the error node in the structure pane to display the errors. Also, in some cases, when there is additional information, the main status bar shows short message, such as "Unable to determine type of expression."

MemberInsight

These options control how CodeInsight displays MemberInsight, the list of accessible methods and data members for the current context.
