Freeze and Unfreeze column [message #1559902]

Hi

I have gone through the sample code of NatTable.
My question is when we apply Freeze on the column, is the OOTB behaviour that the column to the left of freezed column will not be seen unless the unfreeze is again done.

I don't understand the question? OOTB?

I'm still not sure about the concrete question. But the described behavior only occurs in case you are trying to freeze a column position that results in a freeze region that is wider than the available viewport width. Otherwise a user will not be able to interact with the table in a frozen state.

Thnaks for the prompt reply.

My question is:

In the sample examples the freeze and the unfreeze action is called using ctrl+shift+f and ctrl+shift +u respectively.
I have tried to put this on the Menu also that we get by mouse right click on the column.BUT it does not work properly.

The action that is being called on that is:public static <T> IMenuItemProvider withFreezeColumnItemProvider(
final EventList<?> eventList, final IDataProvider bodyDataProvider,
final Composite parent) {
return new IMenuItemProvider() {
@Override
public void addMenuItem(final NatTable natTable,
final Menu popUpMenu) {
freezeMenuItem = new MenuItem(popUpMenu, SWT.NONE);
freezeMenuItem.setText("Freeze Columns\tCtrl+Shift+F");
// freezeMenuItem.setAccelerator(accelerator);

freezeMenuItem.addListener(SWT.Selection, new Listener() {
@Override
public void handleEvent(Event arg0) {

NatEventData obj = (NatEventData) popUpMenu.getData();
final int colIndex = natTable.getColumnIndexByPosition(obj .getColumnPosition());
natTable.doCommand(new FreezeColumnCommand(natTable
.getLayer(), colIndex));
freezeMenuItem.setEnabled(false);
}
});
}
};

When it freezes the columns there is issue with the alignment
but at the same time when ctrl+shift+f/u is being called it works correctly.

Basically the columns that get freezes comes but the horizontal scroll bar disappears,

AFAIK the UI binding triggers the FreezePositionCommand. Also I'm not sure if the index position transformation is necessary as the command gets fired from the top, which leads to automatic transformation.
