    • setDigits

      public void setDigits​(int value)
      Sets the number of decimal places used by the receiver.

      The digit setting is used to allow for floating point values in the receiver. For example, to set the selection to a floating point value of 1.37 call setDigits() with a value of 2 and setSelection() with a value of 137. Similarly, if getDigits() has a value of 2 and getSelection() returns 137 this should be interpreted as 1.37. This applies to all numeric APIs.

      Parameters:
      value - the new digits (must be greater than or equal to zero)
      Throws:
      java.lang.IllegalArgumentException -
      • ERROR_INVALID_ARGUMENT - if the value is less than zero

      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

    • setMaximum

      public void setMaximum​(int value)
      Sets the maximum value that the receiver will allow. This new value will be ignored if it is less than the receiver's current minimum value. If the new maximum is applied then the receiver's selection value will be adjusted if necessary to fall within its new range.
      Parameters:
      value - the new maximum, which must be greater than or equal to the current minimum
      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

    • setMinimum

      public void setMinimum​(int value)
      Sets the minimum value that the receiver will allow. This new value will be ignored if it is greater than the receiver's current maximum value. If the new minimum is applied then the receiver's selection value will be adjusted if necessary to fall within its new range.

      value - the new minimum, which must be less than or equal to the current maximum
      Throws:
      org.eclipse.swt.SWTException -

      value - the page increment (must be greater than zero)
      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

    • setSelection

      public void setSelection​(int selection)
      Sets the selection, which is the receiver's position, to the argument. If the argument is not within the range specified by minimum and maximum, it will be adjusted to fall within this range.
      Parameters:
      value - the new selection (must be zero or greater)
      Throws:
      org.eclipse.swt.SWTException -
      • ERROR_WIDGET_DISPOSED - if the receiver has been disposed

      Parameters:
      limit - new text limit
      Throws:
      java.lang.IllegalArgumentException -
      • ERROR_CANNOT_BE_ZERO - if the limit is zero

      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

      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

    • setFont

      public void setFont​(org.eclipse.swt.graphics.Font font)
      Sets the font that the receiver will use to paint textual information to the font specified by the argument, or to the default font for that kind of control if the argument is null.
      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
      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

    • setForeground

      public void setForeground​(org.eclipse.swt.graphics.Color color)
      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 -
      • ERROR_WIDGET_DISPOSED - if the receiver has been disposed
      • ERROR_THREAD_INVALID_ACCESS - if not called from the thread that created the receiver

    • 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
