Bug 47208 Generate Javadoc dialog lays out too wide [javadoc]
If one uses a custom doclet and sets the doclet class path to a long path (e.g. with many JAR files on it), the "Generate Javadoc" dialog lays out to try and fit the full doclet class path on the screen; this results in a very wide dialog.

Control[] controls;
		protected ToggleSelectionAdapter(Control[] controls) {
			this.controls= controls;

		public void widgetSelected(SelectionEvent e) {
			for (int i= 0; i < controls.length; i++) {
				Control control= controls[i];
				control.setEnabled(!control.getEnabled());
			}
			validate();
		}
		public void validate() {
		}
