Qt add slot to label

You can work around this easily by making a QPushButton like a label by setting the 'flat' property. However, if there are other properties of a QLabel object that you need, here is a code snippet for a custom QLabel which can emit a signal: 'clicked'. In other words, a Clickable QLabel!

When most any slot is called in your code, it is called from the event loop. The event loop can only proceed when you return from the slot, or from the QObject::event method. With Qt 5 and C++11, it's very easy to update the file list from a separate thread.

Select your custom slot, click OK, and build your project. After you do this, the slot will show up in the drop-down, but since a signal/slot connection is created for you at this point, you’ll only need to utilize it from the drop-down if you use it with another signal.

Placing a label next to a slider handle | Qt Forum Hi, I've been trying to place a label with the value next to the slider handle, in a way that it moves with it. I've tried the following code but the label is not positioned exactly by the handle.

I've been having a very hard time figuring out how to properly add QLabels to QWidgets, I tried to set the Main_Window as the main widget using this method: app.setMainWidget(Main_Window) and the label was still outside the window. So how do I put labels into widgets using Qt?

Warning: When passing a QString to the constructor or calling setText(), make sure to sanitize your input, as QLabel tries to guess whether it displays the text as plain text or as rich text. You may want to call setTextFormat() explicitly, e.g. in case you expect the text to be in plain format but cannot control the text source (for instance when displaying data loaded from the Web).
