Communication between ROS and wxWidgets

edit

Hi Ola, I am trying to building a GUI with wxWidgets (using Code::Block). Can you point me where I can find the wxApp::OnRun()? Or where can I read more about it, please.

I don't think it is there by default, but you should place it in the App-class, so something like this: int MyCoolApp::OnRun() { // subscribers and stuf goes here return wxApp::OnRun(); }

Hello, Ola. I have some questions for you, I hope you can answer me.

When you said "Create a timer event that calls ros::spinonce() in its callback method.", did you mean that we have to create a wxTimerEvent? http://docs.wxwidgets.org/trunk/class...

And the other question is: When you said "In OnInit(): call ros::init() (convert wxString in argv to char**)", which argv do you mean?

Thank you in advance.

Yes you should create a wxTimerEvent. In onInit, I do the following: char* argvForRos = new char[argc]; for (int i = 0; i < argc; ++i) { argvForRos[i] = strdup(wxString(argv[i]).mb_str()); } ros::init(argc, _argvForRos, "my

Gui");

Thank you for your answer. In onInit I tried directly with a casting and it worked too: ros::init(argc, (char **) argv, "my_other_GUI");

Again, thank you so much, Ola. You helped me a lot, :)

Hi Ola, Thanks for the answer. However, I am new to C++ and hence struggling a bit. I have tried to incorporate all the things that you said but not working. I want to subscribe to an image from ROS and visualize in the GUI. I am sure there could be several errors in my code but if you could find sometime, please take a look at it https://github.com/ashBabu/Utilities/..., it would be really helpful. Specifically I am struggling to create the timer and 'call subscribe with a reference to the wxFrame objec'. Thanks
