[wxVTK] Small render window issue

[Jason G. <jg...@ui...>]

Okay, so I've gotten things running finally.  But now I have two problems.
wxVTK decides to render on only a small portion of the panel I gave it to
render on.and/or if I set the size of it explicitly to the size of the panel
it takes up the whole panel BUT the mousemotion stuff results in my object
disappearing altogether.

 

I'm making my own frame, but my VTK scene is the same scene as in the
wxSample.proj file included with wxVTK.  It's just the cone that spins.

 

Here's what I'm doing in the constructor of my main wxFrame:

 

wxMedVisFrame::wxMedVisFrame( wxWindow *parent )

      : MainFrame( parent )

{     

      DisplayPanel* displayPanel = new DisplayPanel( this );

      displayPanel->SetInitialSize( this->GetSize() );

 

      // register this panel with wxVTKRenderWindowInteractor

      this->vtkDisplayInteractor = new wxVTKRenderWindowInteractor(
displayPanel, ID_VTK_RENDER_INTERACTOR );

      this->vtkDisplayInteractor->UseCaptureMouseOn();

 

      // initialize VTK scene

      this->InitVTK();

}

 

// THE CODE BELOW SETS UP A SIZER THAT I DON'T USE JUST YET.

// IT'S THERE SO I CAN HAVE A "WINDOWED" MODE LATER, CURRENTLY IT STARTS
WITH STYLE = WXMAXIMIZE

MainFrame::MainFrame( wxWindow* parent, int id, wxString title, wxPoint pos,
wxSize size, int style ) : wxFrame( parent, id, title, pos, size, style )

{

      this->SetSizeHints( wxDefaultSize, wxDefaultSize );

      

      wxFlexGridSizer* MainFrameSizer;

      MainFrameSizer = new wxFlexGridSizer( 2, 2, 0, 0 );

      MainFrameSizer->AddGrowableCol( 0 );

      MainFrameSizer->AddGrowableRow( 1 );

      MainFrameSizer->SetFlexibleDirection( wxBOTH );

      MainFrameSizer->SetNonFlexibleGrowMode( wxFLEX_GROWMODE_SPECIFIED );

      

      this->SetSizer( MainFrameSizer );

      this->Layout();

}

 

DisplayPanel::DisplayPanel( wxWindow* parent, int id, wxPoint pos, wxSize
size, int style ) : wxPanel( parent, id, pos, size, style )

{

      this->SetBackgroundColour( wxColour( 0, 0, 0 ) );

      

}

 

This code results in the panel taking up my entire frame (I know this
because my panels background is black and my frames is gray) but wxVTK only
renders to a small square in the upper left corner.

 

If I explicitly set the size of wxVTKRenderWindowInteractor to the size of
my frame, or even my panel, then it renders to the whole thing but the mouse
interaction is doing something weird because the cone just disappears.

 

The wxSample works fine.

 

Does it have something to do with the constructor for
wxVTKRenderWindowInteractor?
