VScrollTable

public class VScrollTable.VScrollTableBody
extends com.google.gwt.user.client.ui.Panel

This Panel can only contain VScrollTableRow type of widgets. This "simulates" very large table, keeping spacers which take room of unrendered rows.

remove

public boolean remove(com.google.gwt.user.client.ui.Widget w)

Specified by:
remove in interface com.google.gwt.user.client.ui.HasWidgets
Specified by:
remove in class com.google.gwt.user.client.ui.Panel

onAttach

protected void onAttach()

Overrides:
onAttach in class com.google.gwt.user.client.ui.Widget

getRowHeight

public double getRowHeight()

getRowHeight

public double getRowHeight(boolean forceUpdate)

getTableHeight

public int getTableHeight()

getColWidth

public int getColWidth(int columnIndex)

Returns the width available for column content.

Parameters:
columnIndex -
Returns:

setColWidth

public void setColWidth(int colIndex,
                        int w)

Sets the content width of a column. Due IE limitation, we must set the width to a wrapper elements inside table cells (with overflow hidden, which does not work on td elements). To get this work properly crossplatform, we will also set the width of td.

Parameters:
colIndex -
w -

getMaxIndent

protected int getMaxIndent()

This method exists for the needs of VTreeTable only. Returns the maximum indent of the hierarcyColumn, if applicable.

Returns:
maximum indent in pixels
See Also:
VScrollTable#getHierarchyColumnIndex()}

calculateMaxIndent

protected void calculateMaxIndent()

This method exists for the needs of VTreeTable only. Calculates the maximum indent of the hierarcyColumn, if applicable.

moveCol

public void moveCol(int oldIndex,
                    int newIndex)

ensureFocus

protected void ensureFocus()

Ensure the component has a focus. TODO the current implementation simply always calls focus for the component. In case the Table at some point implements focus/blur listeners, this method needs to be evolved to conditionally call focus only if not currently focused.
