      • isResizable

        protected boolean isResizable()
        Description copied from class: Dialog
        Returns a boolean indicating whether the dialog should be considered resizable when the shell style is initially set.

        This method is used to ensure that all style bits appropriate for resizable dialogs are added to the shell style. Individual dialogs may always set the shell style to ensure that a dialog is resizable, but using this method ensures that resizable dialogs will be created with the same set of style bits.

        Style bits will never be removed based on the return value of this method. For example, if a dialog returns false, but also sets a style bit for a SWT.RESIZE border, the style bit will be honored.

        isResizable in class Dialog
        a boolean indicating whether the dialog is resizable and should have the default style bits for resizable dialogs
