Bug 17885 Preference Pages don't resize well
Build: 20020521 The Java preference pages don't look very good when the user makes the preference page dialog narrower or shorter by manually resizing it. Here is a breakdown of problems by page: Builder: "Filtered resources" text field should shrink to fit the dialog width more. Classpath Variables: List box should shrink to fit and should scroll if necessary. Code Formatter: Text box should shrink to fit and should scroll if necessary (the scroll bars are there, why aren't they used?). Step Filtering: List box should shrink horizontally to fit and should scroll if necessary (compare vertical and horizontal behaviour when shrinking the preference page dialog). Editor: In the Syntax tab page, the "Preview" text box should shrink to fit and scroll if necessary. Installed JREs: The table viewer should shrink to fit and scroll if necessary. Javadoc: The "Javadoc command" text field should shrink to fit more. Organize Imports: The list box should shrink to fit and scroll if necessary. Templates: The table viewer should shrink to fit and scroll if necessary.
