          What is "basic routine"? So, what you're running on the device?
          And what do you mean by "tips"?

            Forgive my poor English, "basic" is the official routine name.758e6663-92fe-4cd5-82db-3f06ba6d9239-image.png I didn't get any errors or warnings after running.But when I click on the dialog box, the virtual keyboard doesn't pop up and nothing happens.I used the cross compilation tool to generate the program on the development board.

              Hi,

              Did you check that all the required librairies and plugins are deployed as well ?
              Did you force the use of the virtual keyboard as input method ?

                I think maybe it lacks library files, but when I use the "LDD" command to view it on the embedded development board, it has all the necessary libraries. Maybe this is why there are no errors and warnings.And what do you mean by forcing the use of virtual keyboard? I haven't seen relevant statements in the official documents. If you have any good methods, please let me know. Thank you!!!

                  It's described here in the deployment guide.

                    Thanks for your help. After reading several code projects, I realized that the official source code directly copied lacked an important part, language. When I added this part, my code ran smoothly.09c54b2c-4a07-44b2-bbf0-93fcd8681079-image.png 67600d05-6c71-41bd-b600-2620cc8a6e81-image.png
