Hi,<br>
<br>
Well, this is my problem when I debut on QT + VTK + QTCREATOR:<br>
<br>
MainWindow::MainWindow(QWidget *parent) :<br>
QMainWindow(parent),<br>
ui(new Ui::MainWindow)<br>
{<br>
ui->setupUi(this);<br>
vtkWidget = new QVTKWidget(this,QFlag(0));<br>
ui->verticalLayout->addWidget(vtkWidget);<br>
ui->verticalLayout->update();<br>
ren = vtkRenderer::New();<br>
vtkWidget->GetRenderWindow()->AddRenderer(ren);<br>
ren->SetBackground(1.0,1.0,1.0);<br>
ren->Render();----------------------->PROBLEM!!!! -->>>The inferior stopped because it received a signal from the Operating System. Signal name : SIGSEGV - Signal meaning : Segmentation fault<br>
<br>
}<br>
<br>
When I debut, with Qtcreator everything is ok until the instrucction ren->Render() is executed and have the message: The inferior stopped because it received a signal from the Operating System. Signal name : SIGSEGV - Signal meaning : Segmentation fault.<br>
<br>
I have the same message when at the command line i use qmake, make....<br>
<br>
My Desktop PC has: Ati X1300, the openGL runs so good and the qtdemo is ok.<br>
<br>
On the other hand I have laptop HP with the same S.O ubuntu 9.10 and run QT+VTK+QTCreator, the different thing is the Card which is the NVIDIA, but i don't thing so it would be that because the openGl runs so good in my Desktop PC.<br>
<br>
Another things is that in the Desktop PC I display two monitors in dual-mode thats mean that the graphic card configuration is good.<br>
<br>
What happened?? I know, there are three topics QT,VTK and linux but I so sure the problem is VTK.<br>
<br>
Thanks for all<br>
<br>
Ruben.<br>
