A convenient way to access the Qt documentation from inside Creator, is put the cursor on a class or member-function name you have typed, like QListWidgetItem and press F1. The docs for that widget will show inside the editor. Good way to learn the API while coding.
What a very friendly approach you have. I've watched a number of your videos and find them very informative. What I particularly like is your use UI's rather than the console for demonstration purposes...a far more practical approach. What I'd really like to see you build is an app that comprises multiple userforms connected to a database from which checking for completion, reports generation etc etc., can be generated. In any event thank you so much for sharing your knowledge with me and I look forward to your next tutorial
This was a problem for me too, what I ended up doing was using the file.remove() method before the file.close() in the constructor, this makes it so the document is removed before it is written again, although this may come at the disadvantage that the file could be lost if the program is not closed correctly, although a simple workaround is to keep a backup of this file.
@@wearesciber and the fact that you did write to a file after deleting ui is also a mistake. Btw you made another mistake when implementing remove button, the documentation of qt 6.7 says that you can either delete the pointer or use takeItem which will remove it, so doing both is kind of unecessary either just delete ui listWidget currentItem or takeItem(currentRow)
I am getting the following error: expected unqualified-id before string constant in the following line of code: QFile file(QStandardPaths::writableLocation(QStandardPaths:: DocumentsLocation) . "\\toDoFile.txt"); Can you please tell me how to resolve this error?
Hi! I use the Qt VS Tools extension in Visual Studio 2022, but I don’t see the "Go to Slot" button. I’ve been trying to fix this for a while. How can I resolve this issue? I would appreciate any help! :)
when writing the file after having deleted a task somewhere in the middle of the task list, it is not working as expected. You can fix this by changint the destructor from if (!file.open(QIODevice::ReadWrite)) to if (!file.open(QIODevice::ReadWrite|QFile::Truncate)) what in effect will write the file new from scratch

what's really great about this tutorial is that you are also showing us how did you manage to implement the desired behavior. very nice 👍
Thank you ❤️
You are one of the best explainers i saw on TH-cam. Can you try to make a slightly complex project, I won't mind watching a 2-3 hours video
Thank you. This means a lot. I will try. :)
Best qt tutorial i have ever seen， Thanks！

Keep going with qt c++
Just getting started with Qt and looking for a good intro to it. This was perfect. Thank you!
Excellent teaching skills.....
Thank you ❤️
Wow what a great explanation
Thanks for this
I followed your impedimentation thanks a lot
Thanks Man, m looking for this project
Thank u so much
Awesome tutorial! Do you use a plugin for autocomplete?
Thanks. No i dont use a plugin, its the built in one i think :)
Your remove/remove all was not saved to the file after it has been executed. The text was still there on next run of the program
That’s because he is writing into the file after deleting the ui. The line “delete ui” should be after “file.close();”

@@gfhdlsk You also can change the open-statement and use an additional flag:
if (!file.open(QIODevice::ReadWrite|QFile::Truncate))

Check the syntax again

I found on StackOverflow that the "Go to Slot" button doesn't exist in the Qt VS Tools extension for Visual Studio.

What is the use of Qt designer
It is used to create more sophisticated UIs
Thank you for what you do

Ah yes the cute framework 😚
