问题 In a widget I put two QPushButton (let's say "OK" at left and "EXIT" at right). They regularly work when I press them using the mouse. Suppose I want to switch from one to the other using TAB key: is it possible? And how can do this? 回答1: On some platforms, keyboard focus navigation among buttons is a default behavior, but on some it isn't. If you wish keyboard navigation on all platforms, the buttons should have a Qt::StrongFocus policy set on them. Note that the shortcut used to trigger the

问题 QPushButton can have icon, but I need to set animated icon to it. How to do this? I created new class implemented from QPushButton but how to replace icon from QIcon to QMovie ? 回答1: This can be accomplished without subclassing QPushButton by simply using the signal / slot mechanism of Qt. Connect the frameChanged signal of QMovie to a custom slot in the class that contains this QPushButton . This function will apply the current frame of the QMovie as the icon of the QPushButton . It should

问题 I have a PyQt GUI set up that has a selection of QPushButtons and a QLineEdit text box (among other things). The text box is set up so as to call a function upon returnPressed(). My problem is that when I click on the text box and put in text, one of the buttons becomes selected which means that when I press enter in the text box it activates both the button and the text box function. Is there a way around this? Some way to stop any buttons from being selected while the text box is being

问题 Inspired by Label on QToolBar, possible? I'm trying to develop it. But my button do not blink on click, why?

QApplication a(argc, argv); QMainWindow w; QToolBar barA; barA

问题 I'm trying to do a program which makes some operations with sounds. My question is that I have 3 Play pushbutton and 3 label. I want that whichever I click on the Play button, the sound whose name is in the label that is near the pushbutton should play. I have a play slot without any parameter. So, how can I connect to every play button with every label respectively? Actually, I can write 3 different play function, but since I have some other functions, it will be too long and confusing.
