Common qml development errors (original)

Most errors are caused by the absence of re-compilation or cleanup. Elimination steps:

1. First, exclude basic syntax errors.
2. Clear Project
3. If neither step works, manually delete the directory generated by the program.

 

1. Add a new control, which is not recognized during runtime, as shown in figure

Qrc: UI/Main. qml: 21 mybutton is not a type

Solution: this error is generally caused by incorrect URL during loading. Check whether the URL path to be loaded is correct during C ++ running. The correct URL syntax is: qrc: + (prefix name + prefix internal file path), for example, "qrc: // KKK. qml "," qrc:/customcontrol/tools/test. qml ";

Format template: Qrc:/prefixname/prefixfilepath
