I want to add a linuxcnc gcode preview to my C++ Qt application.

You can embed Gremlin, a snippet
void qtCNC::setupGremlin()
{
int retval;
WId id = 0;
// needed for Gremlin, hardcoded for now
setenv("INI_FILE_NAME", "~/emc2/configs/qtvcp/axis_mm_test.ini", 1);
pid_t pID = vfork();
if (pID == 0) // child
{
retval = execlp("gremlin", "gremlin", (char *) 0);
if(retval == -1)
{
qDebug() << "execlp failed";
exit(1);
}
else
{
qDebug() << "Fork succeeded";
exit(0);
}
}
else if (pID < 0) // failed to fork
{
qDebug() << "Failed to fork";
exit(1);
}
else // parent executes this code
{
// wait until window created
while(id == 0)
{
usleep(5000);
id = QxtWindowSystem::findWindow("gremlin");
}
gremlinEmbedWidget = new QX11EmbedContainer(tabPlot);
gremlinEmbedWidget->embedClient(id);
gremlinEmbedWidget->setGeometry(0,0,tabPlot->width() -
1,tabPlot->height() - 1);
gremlinEmbedWidget->show();
}
}
However I am going to look at Tatlin now:-D
