Constructor Detail

EpctoolsSplitter

                        int style)

Initialization

Method Detail

addFixedSizeChangeListener

public void addFixedSizeChangeListener(java.beans.PropertyChangeListener listener)

This function adds a listener to "this" list of listener

firePropertyChange

protected void firePropertyChange(int old_value,
                                  int new_value)

This function sends a message to all listeners

removeFixedSizeChangeListener

public void removeFixedSizeChangeListener(java.beans.PropertyChangeListener listener)

This function removes a listener

getFixedSize

public int getFixedSize()

This function returns the size (width or height, depending of the orientation of the splitter) of the left most area.

setFixedSize

public void setFixedSize(int m_new_size)

This function sets the size of the left area (see getFixedSize() for more information).

checkStyle

private static int checkStyle(int style)

This function returns the style of the splitter

computeSize

public org.eclipse.swt.graphics.Point computeSize(int w_hint,
                                                  int h_hint,
                                                  boolean changed)

Overrides:

computeSize in class org.eclipse.swt.widgets.Composite

getOrientation

public int getOrientation()

This function answers SWT.HORIZONTAL if the controls in the SashForm are laid out side by side, SWT.VERTICAL if the controls in the SashForm are laid out top to bottom.

getMaximizedControl

public org.eclipse.swt.widgets.Control getMaximizedControl()

This function returns the control that currently is maximized in the SashForm; this value may be null.

getControls

private org.eclipse.swt.widgets.Control[] getControls(boolean m_only_visible)

This function returns an array with all controls

layout

public void layout(boolean changed)

Overrides:

layout in class org.eclipse.swt.widgets.Composite

maintainSize

public void maintainSize(org.eclipse.swt.widgets.Control c)

This function takes care of the control size values.

paint

void paint(org.eclipse.swt.widgets.Sash sash,
           org.eclipse.swt.graphics.GC gc)

This function paints the splitter to the screen.

onDragSash

private void onDragSash(org.eclipse.swt.widgets.Event event)

This function is called when the splitting beam has been moved.

setOrientation

public void setOrientation(int orientation)

This function sets the orientation of the splitter. If orientation is SWT.HORIZONTAL, lay the controls in the SashForm out side by side. If orientation is SWT.VERTICAL, lay the controls in the SashForm out top to bottom.

setLayout

public void setLayout(org.eclipse.swt.widgets.Layout layout)

Overrides:

setLayout in class org.eclipse.swt.widgets.Composite

setMaximizedControl

public void setMaximizedControl(org.eclipse.swt.widgets.Control control)

This function specifies the control that should take up the entire client area of the SashForm. If one control has been maximized, and this method is called with a different control, the previous control will be minimized and the new control will be maximized.. if the value of control is null, the SashForm will minimize all controls and return to the default layout where all controls are laid out separated by sashes.
