Information about all available properties is provided through the casino duisburg poker and dynamicPropertyNames. The parent-child relationship must be set by either passing a pointer to the child's constructoror by calling setParent. You also need to run the Meta Object Compiler on the source file. This example returns all QPushButton s that are children of parentWidget:. When an object is deleted, it emits a destroyed signal. The event is passed q_slots the event parameter. Member Variable Documentation const QMetaObject QObject:: If Qt is unable to deliver the requested number of timer events, it will silently discard some. A slot is a receiving function used to get information about state changes in other widgets. If on the other hand you want to call two different error functions when the number overflows, simply connect the signal to two different slots. This class can tell the outside world that its state has changed by emitting a signal, valueChanged , and it has a slot which other objects can send signals to. QMetaMethod may be used as wildcard in the meaning "any signal" or "any slot in receiving object".
Popular All Time If not, only slots named method will be disconnected, and all other slots are left alone. The method must be 0 if receiver is left out, so you cannot disconnect a specifically-named slot on all objects. See also startTimer , killTimer , and event. Instances of subclasses of QObject should not be thought of as values that can be copied or assigned, but as unique identities. Setting parent to 0 constructs an object with no parent. A meta-object contains information about a class that inherits QObject , e. See also setParent and children. You can find an object by name and type using findChild. In that case, findChildren should be used. They must also derive directly or indirectly from QObject. Note that entering and leaving a new event loop e.

You can check if the QMetaObject:: The protected functions connectNotify and disconnectNotify make it possible to track connections. See also trUtf8 , QApplication:: See also installEventFilter , timerEvent , QApplication:: Note that the destroyed signal will be emitted even if the signals for this object have been blocked. I have read this documentation and still not not fully understand, I updated my original post with what I am attempting to do It is always safe to remove an event q_slots, even during event filter activation i. SIGNAL and SLOT create names from the provided signatures. A slot can be connected to a given signal if the signal has at least as many ohne steuer as the slot, and there is an implicit conversion between the types of the corresponding arguments in the signal and the slot. The return value is the previous value of signalsBlocked. Q_slots same is true whenever you do a system online casino auszahlung ohne einzahlung in a slot; or indirectly call more than ten functions.
