RES: [vtkusers] loading a file

[Renato N. Elias]

Here is a short example how I do this in Qt.

// Action to be taken upon file open 
void SimpleView::fileOpen()
{
	QString filename = QFileDialog::getOpenFileName(this,
								tr("Open
Ensight case file"), ".",
								tr("Ensight
case (*.case);;All Files (*)"));

	if (!filename.isEmpty()) {

		reader = vtkGenericEnSightReader::New();
		reader->SetCaseFileName(filename.toStdString().c_str());
		reader->Update();
		//---------------------------------------------
		geom = vtkGeometryFilter::New();
		geom->SetInputConnection(reader->GetOutputPort());
		//---------------------------------------------
		mapper = vtkPolyDataMapper::New();
		mapper->SetInputConnection( geom->GetOutputPort() );
            //---------------------------------------------
            actor = vtkActor::New();
            actor->SetMapper( mapper );
		//--------------------------------------------
		ren->AddActor(actor);
		ren->ResetCamera();
		ren->GetRenderWindow()->Render();
		//---------------------------------------------
		a_fileSaveAs->setEnabled(true);

	}
} 

I hope it helps you

Renato.

Assunto: [vtkusers] loading a file

Hi there

I am new to VTK and have just finished some coding. My application reads a
.stl file and displays it. At the moment I have hardcoded the
filename:

vtkSTLReader *sr = vtkSTLReader::New();
	sr->SetFileName("Ear.stl");

Now I would like to have a prompt-window (like the browse-button) from where
I can choose my desired STL-file to be read. So in the end the last line
from above would look like:

sr->SetFileName(filename);

What do I have to do?

Thanks in advance
Lam
