Hello guys.
I am having trouble with QTabWidget:
I can't add multiple widgets with addTab nor insertTab.
even when I try something like:
It will raise an error that the first argument (layout) is wrong. :/
Please, any help?

It will raise an error that the first argument (layout) is wrong. :/
Please, any help?

There is not enough code here or enough of the error message to help you. If you are not using a class, the "self." will yield errors. This is an example using QVBoxLayout that hopefully will help.

I'm still using qt3, but it should be somewhere in the vicinity of this

self.tab_1 = QWidget() self.tab_1.setObjectName("Create Tab") self.tabs.addTab(self.tab_1, "") self.layout.addWidget(self.tabs)
