Method Details

computeSize
public org.eclipse.swt.graphics.Point computeSize(org.eclipse.swt.graphics.GC gc, int wHint, int hHint, java.lang.Object value)Returns the size of the given value's visual representation.- Parameters:
gc
- convenience GC for string and text extentswHint
- given width (or SWT.DEFAULT)hHint
- given height (or SWT.DEFAULT)value
- value to be sized- Returns:
- the size
-
paint
public void paint(org.eclipse.swt.graphics.GC gc, java.lang.Object value)Paints the visual representation of the given value on the given GC. The actual class of the value object is determined by the use of the implementing class.Implementors need to respect the bounds values that may have been specified. The bounds values may affect the x and y values for all drawing operations as well as the width and heights. Implementors may use a
Transform
to translate the coordinates of all the drawing operations, otherwise they will need to offset each draw.- Parameters:
gc
- GC to paint withvalue
- the value being painted
-
notify
public boolean notify(int event, org.eclipse.swt.graphics.Point point, java.lang.Object value)Mechanism used to notify the light weight widgets that an event occurred that it might be interested in.- Parameters:
event
- Event type.point
- Location of event.value
- New value.- Returns:
- widget handled the event.
-
getTextBounds
public org.eclipse.swt.graphics.Rectangle getTextBounds(java.lang.Object value, boolean preferred)Returns the bounds of the text in the cell. This is used when displaying in-place tooltips. Ifnull
is returned here, in-place tooltips will not be displayed. If thepreferred
argument istrue
then the returned bounds should be large enough to show the entire text. Ifpreferred
isfalse
then the returned bounds should be be relative to the current bounds.- Overrides:
getTextBounds
in classGridFooterRenderer
- Parameters:
value
- the object being rendered.preferred
- true if the preferred width of the text should be returned.- Returns:
- bounds of the text.
