        org.eclipse.swt.SWTException -
        • ERROR_WIDGET_DISPOSED - if the receiver has been disposed
        • ERROR_THREAD_INVALID_ACCESS - if not called from the thread that created the receiver
      • convertSelectionToStringValue

        private java.lang.String convertSelectionToStringValue()
        Convert the selection into a string
        Returns:
        the string representation of the selection
      • setTextLimit

        public void setTextLimit​(int limit)
        Sets the maximum number of characters that the receiver's text field is capable of holding to be the argument.

        To reset this value to the default, use setTextLimit(Spinner.LIMIT). Specifying a limit value larger than Spinner.LIMIT sets the receiver's limit to Spinner.LIMIT.

        Parameters:
        limit - new text limit
        Throws:
        java.lang.IllegalArgumentException -
        • ERROR_CANNOT_BE_ZERO - if the limit is zero
        org.eclipse.swt.SWTException -
        • ERROR_WIDGET_DISPOSED - if the receiver has been disposed
        • ERROR_THREAD_INVALID_ACCESS - if not called from the thread that created the receiver
        See Also:
        #LIMIT
      • setValues

        public void setValues​(int selection,
                              int minimum,
                              int maximum,
                              int digits,
                              int increment,
                              int pageIncrement)
        Sets the receiver's selection, minimum value, maximum value, digits, increment and page increment all at once.

        Note: This is similar to setting the values individually using the appropriate methods, but may be implemented in a more efficient fashion on some platforms.

        Parameters:
        selection - the new selection value
        minimum - the new minimum value
        maximum - the new maximum value
        digits - the new digits value
        increment - the new increment value

        Sets the receiver's drag detect state. If the argument is true, the receiver will detect drag gestures, otherwise these gestures will be ignored.
        Overrides:
        setFocus in class org.eclipse.swt.widgets.Composite
        Parameters:
        dragDetect - the new drag detect state

        Overrides:
        forceFocus in class org.eclipse.swt.widgets.Control
        Returns:
        true if the control got focus, and false if it was unable to.
        Throws:

        Sets the receiver's cursor to the cursor specified by the argument, or to the default cursor for that kind of control if the argument is null.

        When the mouse pointer passes over a control its appearance is changed to match the control's cursor.

        Overrides:
        setCursor in class org.eclipse.swt.widgets.Control
        Parameters:
        cursor - the new cursor (or null)

      • setEnabled

        public void setEnabled​(boolean enabled)
        Enables the receiver if the argument is true, and disables it otherwise. A disabled control is typically not selectable from the user interface and draws with an inactive or "grayed" look.
        Overrides:
        setEnabled in class org.eclipse.swt.widgets.Control
        Parameters:
        enabled - the new enabled state

        Overrides:
        setFont in class org.eclipse.swt.widgets.Control
        Parameters:
        font - the new font (or null)
        Throws:
        java.lang.IllegalArgumentException -
        • ERROR_INVALID_ARGUMENT - if the argument has been disposed

        Sets the receiver's foreground color to the color specified by the argument, or to the default system color for the control if the argument is null.

        Note: This operation is a hint and may be overridden by the platform.

        Overrides:
        setForeground in class org.eclipse.swt.widgets.Control
        Parameters:
        color - the new color (or null)
        Throws:
        java.lang.IllegalArgumentException -
        • ERROR_INVALID_ARGUMENT - if the argument has been disposed
        org.eclipse.swt.SWTException -

      • setMenu

        public void setMenu​(org.eclipse.swt.widgets.Menu menu)
        Sets the receiver's pop up menu to the argument. All controls may optionally have a pop up menu that is displayed when the user requests one for the control. The sequence of key strokes, button presses and/or button releases that are used to request a pop up menu is platform specific.

        Note: Disposing of a control that has a pop up menu will dispose of the menu. To avoid this behavior, set the menu to null before the control is disposed.

        Overrides:
        setMenu in class org.eclipse.swt.widgets.Control
        Parameters:
        menu - the new pop up menu
        Throws:
        java.lang.IllegalArgumentException -
        • ERROR_MENU_NOT_POP_UP - the menu is not a pop up menu
        • ERROR_INVALID_PARENT - if the menu is not in the same widget tree
        • ERROR_INVALID_ARGUMENT - if the menu has been disposed
        org.eclipse.swt.SWTException -
        • ERROR_WIDGET_DISPOSED - if the receiver has been disposed
        • ERROR_THREAD_INVALID_ACCESS - if not called from the thread that created the receiver
      • setToolTipText

        public void setToolTipText​(java.lang.String tooltipText)
        Sets the receiver's tool tip text to the argument, which may be null indicating that the default tool tip for the control will be shown. For a control that has a default tool tip, such as the Tree control on Windows, setting the tool tip text to an empty string replaces the default, causing no tool tip text to be shown.

        The mnemonic indicator (character '&') is not displayed in a tool tip. To display a single '&' in the tool tip, the character '&' can be escaped by doubling it in the string.

        Overrides:
        setToolTipText in class org.eclipse.swt.widgets.Control
        Parameters:
        string - the new tool tip text (or null)
        Throws:
        org.eclipse.swt.SWTException -
        • ERROR_WIDGET_DISPOSED - if the receiver has been disposed
        • ERROR_THREAD_INVALID_ACCESS - if not called from the thread that created the receiver
