Hide wxDataViewCtrl expander

[Ramón Berrutti]

Hi, it is posible to hide the expander of wxDataViewCtrl, i am doing my own
wxDataViewModel

I see this on datavgen.cpp

// Draw the expander here.
int indent = 0;
if ((!IsVirtualList()) && (col == expander))
{
indent = node->GetIndentLevel();

// Calculate the indent first
indent = cell_rect.x + GetOwner()->GetIndent() * indent;

int expander_width = m_lineHeight - 2*EXPANDER_MARGIN;

// change the cell_rect.x to the appropriate pos
int expander_x = indent + EXPANDER_MARGIN;
int expander_y = cell_rect.y + EXPANDER_MARGIN + (GetLineHeight(item) / 2)
- (expander_width/2) - EXPANDER_OFFSET;

indent = indent + m_lineHeight;
// try to use the m_lineHeight as the expander space

dc.SetPen( m_penExpander );
dc.SetBrush( wxNullBrush );
if( node->HasChildren() )
{
wxRect rect( expander_x , expander_y, expander_width, expander_width);
int flag = 0;
if (m_underMouse == node)
{
flag |= wxCONTROL_CURRENT;
}
if( node->IsOpen() )
wxRendererNative::Get().DrawTreeItemButton( this, dc, rect,
flag|wxCONTROL_EXPANDED );
else
wxRendererNative::Get().DrawTreeItemButton( this, dc, rect, flag);
}

// force the expander column to left-center align
cell->SetAlignment( wxALIGN_CENTER_VERTICAL );
}


But I don't understand how I can delete.


I need to show:


Node1

item1

item2

Node2

item1

item2


o now like:


+ Node1

Item1

Item2

+ Node2

Item 1

Item 2


Thanks!!

You can't hide the expander if you have any items with children (which
seems to make sense to me...).

Thanks!! I am making a VirtualList with a Listmanager to get this work.
