Here is the caller graph for this function:

◆ qt_v4DebuggerHook()

Q_QML_EXPORT int qt_v4DebuggerHook ( const char * json )

Since: 5.5

The main entry point into "Native Mixed" Debugging.

Commands are passed as UTF-8 encoded JSON data. The data has two compulsory fields: \list

version: Version of the protocol (currently 1)
command: Name of the command \endlist

Depending on command, more fields can be present.

Error is indicated by negative return values, success by non-negative return values.

protocolVersion: Returns version of implemented protocol.

insertBreakpoint: Sets a breakpoint on a given file and line. \list

fullName: Name of the QML/JS file
lineNumber: Line number in the file
condition: Breakpoint condition \endlist Returns a unique positive number as handle.

removeBreakpoint: Removes a breakpoint from a given file and line. \list

fullName: Name of the QML/JS file
lineNumber: Line number in the file
condition: Breakpoint condition \endlist Returns zero on success, a negative number on failure.

prepareStep: Puts the interpreter in stepping mode. Returns zero.

◆ qt_v4ResolvePendingBreakpointsHook()

Q_QML_EXPORT void qt_v4ResolvePendingBreakpointsHook ( )

Since: 5.5

This function is called uncondionally from VME::run().

An attached debugger can set a breakpoint here to intercept calls to VME::run().

◆ qt_v4TriggeredBreakpointHook()

Q_QML_EXPORT void qt_v4TriggeredBreakpointHook ( )

Since: 5.5

This function is called when a QML interpreter breakpoint is hit.

An attached debugger can set a breakpoint here.
