newbie: Qt 5.7 install issues and other problems

[jimb]

So I want to put a GUI on top of my software. I figure Qt might be a good way to go. So I download 5.7 on my Mac running 10.11.13 (El Capitan).

Issue #1: Qt 5.7 is installed where I specified, but in the Application tab in finder, Qt is never installed. I need to grab the Qt icon during the install of Qt Creator and drag it to the dock.

Issue #2: Downloaded Qt 4.8 and found that it is incompatible with my version of MacOS, so it seems I am stuck with 5.7.

Issue #3: Looking for a good book on Qt 5. I can't seem to find one. Amazon has a few books but the reviews don't give me any confidence that they would be good teaching tools. There is online documentation. But I have not found any good explanations of how to use the Qt classes/frameworks. Can someone either point me to a link that can get me started or provide the name of a good book on Qt5 that would help me out?

Thanks, Jim

Hi and welcome to devnet forum

Did you see this page?

In general you will more books on Qt 4 which is the predecessor of Qt 5. For quite no books had been published on Qt since the differences are not really huge. Therefore, also books on Qt 4 are not completely outdated. In most cases only a few adaptations are required when migrating from Qt 4 to Qt 5.

With your Mac OS question I do not know details since I am a Windows user. However, I do not think that there should be general problem there. From where did you download and install Qt 4.8?

Just small note:

Issue #2: Downloaded Qt 4.8 and found that it is incompatible with my version of MacOS

There is always the option to compile the 4.8 version with whatever version of Xcode/compiler you like.

They (also) seem to mention
brew install qt4
Which seems to be a packet manager

Not sure it would make it easier. :)

But, Qt5 did introduce QML, which QT4 does not have. So if I do buy a book on Qt4 I will not get any understanding of QML from the book.
