SizeCache
public SizeCache()
SizeCache
public SizeCache(
Control control)
- Creates a cache for size computations on the given control
-
Parameters:
-
control
- the control for which sizes will be calculated,
or null to always return (0,0)
setControl
public void setControl(
Control newControl)
- Sets the control whose size is being cached. Does nothing (will not
even flush the cache) if this is the same control as last time.
-
-
Parameters:
-
newControl
- the control whose size is being cached, or null to always return (0,0)
getControl
public
Control getControl()
- Returns the control whose size is being cached
-
-
Returns:
- the control whose size is being cached, or null if this cache always returns (0,0)
flush
public void flush()
- Flush the cache (should be called if the control's contents may have changed since the
last query)
-
flush
public void flush(boolean recursive)
-
computeSize
public
Point computeSize(int widthHint,
int heightHint)
- Computes the preferred size of the control.
-
-
Parameters:
-
widthHint
- the known width of the control (pixels) or SWT.DEFAULT if unknown -
heightHint
- the known height of the control (pixels) or SWT.DEFAULT if unknown
-
Returns:
- the preferred size of the control
computeAdjustedSize
public
Point computeAdjustedSize(int widthHint,
int heightHint)
- Compute the control's size, and ensure that non-default hints are returned verbatim
(this tries to compensate for SWT's hints, which aren't really the outer width of the
control).
-
-
Parameters:
-
widthHint
- the horizontal hint -
heightHint
- the vertical hint
-
Returns:
- the control's size
computeMinimumWidth
public int computeMinimumWidth()
-
computeMaximumWidth
public int computeMaximumWidth()
-
computeMinimumSize
public
Point computeMinimumSize()
-
setSize
public void setSize(
Point newSize)
-
setSize
public void setSize(int width,
int height)
-
setBounds
public void setBounds(int x,
int y,
int width,
int height)
-
setBounds
public void setBounds(
Rectangle bounds)
-
layoutIfNecessary
public void layoutIfNecessary()
-
