Note that subclasses do not have to handle all types and may also implement more of necessary.

Parameters:

eventType -

cell -

computeContentHeight

protected void computeContentHeight(int eventType,
                                    CTreeColumn column)

Compute the height of the Content area after the given column has experienced an event of the given type.

Event types:

• SWT.Move
• SWT.Resize

Note that subclasses do not have to handle all types and may also implement more of necessary.

Parameters:

eventType -

column -

computeContentHeight

protected void computeContentHeight(int eventType,
                                    CTreeItem item)

Compute the height of the Content area after the given item has experienced an event of the given type.

Event types:

• SWT.Hide
• SWT.Move
• SWT.Show

Note that subclasses do not have to handle all types and may also implement more of necessary.

Parameters:

eventType -

item -

computeSize

protected org.eclipse.swt.graphics.Point computeSize(org.eclipse.swt.widgets.Composite composite,
                                                     int wHint,
                                                     int hHint,
                                                     boolean flushCache)

Specified by:

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

getItemHeight

int getItemHeight()

layout

protected void layout(org.eclipse.swt.widgets.Composite composite,
                      boolean flushCache)

Specified by:

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

layout

void layout(int eventType,
            CTreeCell cell)

Layout the Content area after the given cell has experienced an event of the given type.

Event types:

• SWT.Collapse
• SWT.Expand
• SWT.Resize

Note that subclasses do not have to handle all types and may also implement more of necessary.

Parameters:

eventType -

cell -

layout

void layout(int eventType,
            CTreeColumn column)

Layout the Content area after the given column has experienced an event of the given type.

Parameters:

eventType -

column -

layout

void layout(int eventType,
            CTreeItem item)

Layout the Content area after the given item has experienced an event of the given type. Because an event has occurred, indicating a change in content, computeSize will be called.
