By Guest

Since we already have an implementation for invoking any Qt Slot from Python, it looked promising to use this approach for the extension of wrapped objects as well. This avoids that the PythonQt user needs to care about how Python arguments are mapped from/to Qt when he wants to create static methods, constructors and additional member functions.

The example below uses the well known clicked signal from a QPushButton. The connect method has a non python-friendly syntax. The .setWindowTitle call at the end of the __init__ block changes the window title and triggers the .windowTitleChanged signal, which emits the new window title as a str.We've attached a series of intermediate slot functions (as lambda functions) which modify this signal and then call our custom slots with different parameters. To establish a signal and slot connection between two widgets in a dialog, you first need to switch to Qt Designer's Edit Signals/Slots mode. To do that, you can press the F4 key, select the Edit>Edit Signals/Slots option in the main menu, or click on the Edit Signals/Slots button on the toolbar. Nov 17, 2020 · The slotSignature has the same form as a signalSignature except that the name is of a Qt slot. A slot may not have more arguments than the signal that is connected to it, but may have less; the additional parameters are then discarded. All the information (slot to call, parameter values, ) are stored inside the event. Copying the parameters. The argv coming from the signal is an array of pointers to the arguments. The problem is that these pointers point to the stack of the signal where the arguments are. Once the signal returns, they will not be valid anymore.

It is important to remember that a QThread instance lives in the old thread that instantiated it, not in the new thread that calls run(). This means that all of QThread's queued slots and invoked methods will execute in the old thread. Thus, a developer who wishes to QT slot function does not get called. arjoshi77 asked on 2011-10-20.

For instance, to make a QApplication, call Qt::Application( \@ARGV ); SUBCLASSING. To create a subclass of a Qt class, declare a package, and then declare that package's base class by using QtCore4::isa and passing it an argument.

Qt uses signals and slots normally in a single thread, so calling a signal will call a slot in the same thread signal called. Is it any way to use a signal-slot mechanism to pass a message to qt thread ( so slot will be called later in specified thread's context )? The 'connect' needs at argument 2 and 4 a function pointer.
