QT Notepad tutorial

@SeanR
your link doesn't point to a tutorial but to the docs of the QAction class?Anyway i can only tell how to do this programmatically and not with QtDesigner (since i never used it yet honestly). You need to create QAction instances and connect their triggered()-signal to custom slots. In there you do the work.
For "new" you could call clear() on the textedit. For "open" you can open a QFileDialog, for "print" call print() on the textedit, for "exit" you could call QApplication::instance()->quit() for example.@raven-worx
You are correct. I copied the wrong link. Sorry that has been corrected. I copied the verbiage in the original post. You will be able to see the link now. It's very confusing. I am new to UI work and and QT. Just started about 5 hours ago. -

Hi,
Creator seems not to create an action for a top menu.
It works as sample says for sub items, but either i miss some little step in the description or
it has changed since example was written.

Ok, I see what is going on. I believe whomever wrote the guide was a little familiar with GT UI. So unfortunately, as I was not I got lost and completed the task wrong. What the guide should say is double click, "Type here" and change to "File". Then proceed to create the following items under "File".
- New
- Open
- Save
- Save as
- Exit
At this point the inaction items will be created for you. Unfortunately, my screen grabbing utility on Mac causes the file menu to collapse. So you can see it in the image. See example below.

Ah, now it all makes sense. :)
Good work.
Please feel free to ask about designer if you get stuck again. -
@mrjj I most definitely will. I have a couple of projects that I want to create for both iOS, MacOSX and Windows. I am even considering a port to Linux. I think this might be the easiest way for me to do this. So far I am really enjoying this quest.

Yes, Qt will help a loooong way making the app cross platform.
Depending on what features you use, it might be a simple recompile and its running.
Note that using virtual machines for each platform is often far less work then
setting up cross compiling from one platform to the others.One note. When you use Designer, c++ code is generated for you.
If you press F2 on ui->setupUi(this); in mainwindow constructor you can see
how the UI is being created. This i found useful for understanding how stuff worked.
Also if you add widgets dynamically to a Designer created class/form, always
put it UNDER that line :) -

Right now I am trying to track down where to put the declarations of the inaction stuff. In my first project it was Class / private ....How do I clear out an old project?

Actually, I reset the project and started over. My old project was busted. The answer to my question was "private slot:"

Ok, so here is my next question. I have finally got the application semi working. I have an issue though. Please ignore the missing icons. I was just doing it for a test type thing.
Why does my application not have a "File" & "Edit" menu??
Yes, I can drag the icons out. But I really liked the fact the tutorial can have a file menu.

@SeanR Isn't the application menu on the top bar in MacOS and not in the application window itself?

Good call. I being mostly a MacDev noob and tired failed to look up there. Ty, I was expecting to see on the application. Minus 50 dragon kill points for me...
