Unable to find a member function of qtabwidget

[SId7117]

Hi all,

I could not find "void QTabWidget::setTabVisible(int index, bool visible)" under Qtabwidget documentation on the windows environment but the same is available in RHEL. Do the member functios of a qwidget differ with windows or Linux?

See https://doc.qt.io/qt-5/qtabwidget.html#setTabVisible - it was added in 5.15

@Christian-Ehrlicher thanks for the reply.

I tried to update Qt through the maintenance tool but it shows no update available.

From 5.14.1 to 5.15 is not an "update" in the installer.
You need to install it by "Add or remove components" since different versions are considered as different components.

@Bonnie thank you for the reply.

Qt asks to update the maintenance tool while adding/removing components. How can i update this tool?

[Bonnie]

Well, that one should be updated by "Update components". I'm not sure why you got no updates available. Maybe it is the network thing?
Or maybe your maintenance tool is too old to be updated, in that case you can only remove all components and download the latest online installer.
