    • setUnselectedHotTabsColorBackground

      public void setUnselectedHotTabsColorBackground(Color color)
      Specified by:

    • computeTrim

      protected Rectangle computeTrim(int part, int state, int x, int y, int width, int height)
      Description copied from class: CTabFolderRenderer
      Given a desired client area for the part (as described by the arguments), returns the bounding rectangle which would be required to produce that client area.

      In other words, it returns a rectangle such that, if the part's bounds were set to that rectangle, the area of the part which is capable of displaying data (that is, not covered by the "trimmings") would be the rectangle described by the arguments (relative to the receiver's parent).

      Overrides:
      computeTrim in class CTabFolderRenderer
      Parameters:
      part - one of the part constants
      state - the state of the part
      x - the desired x coordinate of the client area
      y - the desired y coordinate of the client area
      width - the desired width of the client area
      height - the desired height of the client area
      Returns:
      the required bounds to produce the given client area

    • computeSize

      protected Point computeSize(int part, int state, GC gc, int wHint, int hHint)
      Description copied from class: CTabFolderRenderer
      Returns the preferred size of a part.

      The preferred size of a part is the size that it would best be displayed at. The width hint and height hint arguments allow the caller to ask a control questions such as "Given a particular width, how high does the part need to be to show all of the contents?" To indicate that the caller does not wish to constrain a particular dimension, the constant SWT.DEFAULT is passed for the hint.

      The part value indicated what component the preferred size is to be calculated for. Valid values are any of the part constants:

      • PART_BODY
      • PART_HEADER
      • PART_BORDER
      • PART_BACKGROUND
      • PART_MAX_BUTTON
      • PART_MIN_BUTTON
      • PART_CHEVRON_BUTTON
      • PART_CLOSE_BUTTON
      • A positive integer which is the index of an item in the CTabFolder.

      The state parameter may be one of the following:

      • SWT.NONE
      • SWT.SELECTED - whether the part is selected
      Overrides:
      computeSize in class CTabFolderRenderer
      Parameters:
      part - a part constant
      state - current state
      gc - the gc to use for measuring
      wHint - the width hint (can be SWT.DEFAULT)
      hHint - the height hint (can be SWT.DEFAULT)
      Returns:
      the preferred size of the part

    • draw

      protected void draw(int part, int state, Rectangle bounds, GC gc)
      Description copied from class: CTabFolderRenderer
      Draw a specified part of the CTabFolder using the provided bounds and GC.

      The valid CTabFolder part constants are:

      • PART_BODY - the entire body of the CTabFolder
      • PART_HEADER - the upper tab area of the CTabFolder
      • PART_BORDER - the border of the CTabFolder
      • PART_BACKGROUND - the background of the CTabFolder
      • PART_MAX_BUTTON
      • PART_MIN_BUTTON
      • PART_CHEVRON_BUTTON
      • PART_CLOSE_BUTTON
      • A positive integer which is the index of an item in the CTabFolder.

      The state parameter may be a combination of:

      • SWT.BACKGROUND - whether the background should be drawn
      • SWT.FOREGROUND - whether the foreground should be drawn
      • SWT.SELECTED - whether the part is selected
      • SWT.HOT - whether the part is hot (i.e. mouse is over the part)
      Overrides:
      draw in class CTabFolderRenderer
      Parameters:
      part - part to draw
      state - state of the part
      bounds - the bounds of the part
      gc - the gc to draw the part on
