Hello I manage to follow the tutorial and made it work on my project to integrate librviz in a qt4 qwidget. My problem now is that i want to publish a message from type point cloud2 in the librviz i manage to find some inputs and follow them and i think I'm linked to the right topic and all but the rviz window doesn't draw anything into the screen and it doesn't replay any error so could you help me. I leave here my code, I'm playing a bag with the topic that I'm subscribing.

render_panel_->setSizePolicy(QSizePolicy::Expanding,QSizePolicy::Expanding); manager_ = new rviz::VisualizationManager( render_panel_ ); render_panel_->initialize( manager_->getSceneManager(), manager_ ); manager_->initialize(); manager_->startUpdate();

// Create a Grid display.

grid1_ = manager_->createDisplay( "rviz/PointCloud2", "/octomap_point_cloud_centers", true ); ROS_ASSERT( grid1_ != NULL );

// // Configure the GridDisplay the way we like it.

grid1_->subProp("Topic")->setValue("/my_cloud");

grid1_->subProp( "Color" )->setValue( Qt::yellow );

grid1_->setFixedFrame("/world");

grid1_->subProp("Style")->setValue("Flat Squares");

grid1_->setProperty("Size",0.1);

grid1_->setProperty("Decay Time",10);

I'm trying to do something similar but with a point cloud2 tipe of message the problem is that i don't get any errors but it doesn't display anything. my code is this

manager_ = new rviz::VisualizationManager( render_panel_ ); render_panel_->initialize( manager_->getSceneManager(), manager_ ); manager_->initialize(); manager_->startUpdate();

grid1_ = manager_->createDisplay( "rviz/PointCloud2", "/octomap_point_cloud_centers", true );

ROS_ASSERT( grid1_ != NULL );

grid1_->subProp("Topic")->setValue("/my_cloud"); grid1_->subProp( "Color" )->setValue( Qt::yellow ); grid1_->setFixedFrame("/world"); grid1_->subProp("Style")->setValue("Flat Squares"); grid1_->setProperty("Size",0.1); grid1_->setProperty("Decay Time",10); Could you help me
