FilteredItemsSelectionDialog - refreshing content provider [message #328955]

Hi all,

I have a filtered content selection dialog, and in the extended content
area I have a checkbox that adds an extra filter. I added a selection
listener to the checkbox so that whenever the user selects/deselects it,
I want the dialog to empty its content and re-call
fillContentProvider(). However, I can't seem to make it do this (I've
tried refesh(), scheduleRefresh() and reloadCache()).

Is there any way to force the dialog to call fillContentProvider().
Short of that, I can't even seem to make it call matches() on every
item, so is there a way to force it to do that and re-match the items?

Thanks,
Robert

Have you tried calling applyFilter()? In order for that to work, the new
filter will have to be different from the previous one.

Hope this helps,
Eric

Okay, this is really weird. I'm initializing the dialog with "**" and at
that point if I check/uncheck the box in the extended content area,
nothing happens. But if I change the filter text to something else &
then go back to ** and check/uncheck the box which is supposed to change
the filter, it works fine.

Relevant code (I've tried to remove everything not relevant to this
particular issue):
==============
private abstract class AbstractModuleFilter extends ItemsFilter
{
public boolean isConsistentItem(Object item)
{
return true;
}

public boolean matchItem(Object item)
{
return matches(getName(item));
}
}

private final class AllModulesFilter extends AbstractModuleFilter
{
@Override
public boolean equalsFilter(ItemsFilter filter)
{
return filter instanceof AllModulesFilter &&
super.equalsFilter(filter);
}
}

private final class OnlyMainFilter extends AbstractModuleFilter
{
@Override
public boolean matchItem(Object item)
{
return isMainModule(item) && super.matchItem(item);
}

@Override
public boolean equalsFilter(ItemsFilter filter)
{
return filter instanceof OnlyMainFilter &&
super.equalsFilter(filter);
}
}

@Override
protected Control createExtendedContentArea(Composite parent)
{
// ...[snip creating a composite with fOnlyMainCheckbox]...

fOnlyMainCheckbox.addSelectionListener(new SelectionAdapter()
{
@Override
public void widgetSelected(SelectionEvent e)
{
fOnlyMain = fOnlyMainCheckbox.getSelection();
applyFilter();
}
});

return comp;
}

@Override
protected ItemsFilter createFilter()
{
return fOnlyMain ? new OnlyMainFilter() : new AllModulesFilter();
}
======

Than you so much for your help,
Robert
