the optional block prevents the application from running until the debug client connects to the server.

the optional ip address specifies the IP address of the host where the application is running.

the mandatory port_from specifies either the debugging port or the start port of a range of ports when port_to is specified.

To enable debugging - from the start or to attach a debugger later on - start the application with the following arguments: When the infrastructure is enabled, the application displays the following warning: Note: Enabling the debugging infrastructure may compromise the integrity of your application and system, and therefore, you should only enable it in a controlled environment. Set the QML_IMPORT_TRACE environment variable to enable debug output from QML's import loading mechanisms.ДЇor example, for a simple QML file like this: Ensure that a client is attached before ending //the profiling session.Д¬onsole.exception prints an error message together with the stack trace of JavaScript execution at the point where it is called. Call some function that needs to be profiled. A profiling client needs to be attached before this call to receive and store the profiling data. Calling this function without a previous call to console.profile prints a warning to the console. Nested calls are not supported and prints a warning to the console.Д¬onsole.profileEnd turns off the QML and JavaScript profilers. whenever f() is run.Д¬onsole.profile turns on the QML and JavaScript profilers.

The code sample above prints f called: 1, f called: 2. The stack trace is limited to last 10 stack frames.Д¬unt prints the current number of times a particular piece of code has run, along with a message. This stack trace information contains the function name, file name, line number, and column number. Both take a string argument that identifies the measurement.Д¬ace prints the stack trace of the JavaScript execution at the point where it was called. assert(x > 12, 'This will fail') Д¬onsole.time and console.timeEnd log the time (in milliseconds) that was spent between the calls. assert(x = 12, 'This will pass') Д¬onsole. If not, it writes an optional message to the console and prints the stack trace.Д¬onsole.

See also Debugging Techniques.Д¬onsole.assert tests that an expression is true. The output is generated using the qCDebug, qCWarning, or qCCritical methods in C++, with a category of qml or js, depending on the type of file doing the logging. Use console.log, bug,, console.warn, or console.error to print debugging information to the console.Д¬onsole.
