I added some qDebug code in Module::copyToClipboard() and noticed that the method is always called twice when the Copy to clipboard button is clicked. When I remove the line 125 in Module.cpp: connect(ui->pushButtonCopyInfo, &QPushButton::clicked, this, &Module::copyToClipboard); then the nothing happens when the button is clicked. With a web search I only found this https://stackoverflow.com/questions/34416103/function-connected-to-the-button-is-called-twice-after-one-click which is not the case here. Any idea why the slot method is called twice?
