The following class members are part of the Qt 3 support layer. They are provided to help you port old code to Qt 4. We advise against using them in new code.
void | lock () |
bool | locked () |
bool | tryLock () |
void | unlock ( bool wakeUpGui = true ) |
int | argc () |
char ** | argv () |
int | enter_loop () |
void | exit_loop () |
int | loopLevel () |
void | processOneEvent () |

This function enters the main event loop (recursively). Do not call it unless you really know what you are doing.
This function exits from a recursive call to the main event loop. Do not call it unless you are an expert.
In Qt 3, this function locked the Qt library mutex, allowing non-GUI threads to perform basic printing operations using QPainter.
In Qt 4, this is no longer supported, since painting is only supported from within a paint event handler. This function does nothing.
See also QWidget::paintEvent().
This function does nothing. It is there to keep old code working. It always returns false.
See lock() for details.
Returns the current loop level.
Waits for an event to occur, processes it, then returns.
This function is useful for adapting Qt to situations where the event processing must be grafted onto existing program loops.
Using this function in new applications may be an indication of design problems.
See also processEvents(), exec(), and QTimer.
