How to step into the Qt source code (Qt 5.15.2 / Windows) ?

Alvein

Hello.

I already tried to follow some instructions like the ones here:

https://stackoverflow.com/questions/44734160/i-cant-step-into-qt-source-code-on-windows

I have downloaded the source code and those "debug information files" which are like 13GB in size.

My Qt version is 5.15.2 MSVC2019

Apart of setting these paths (in case they are correct), what more should I do?

Anybody can point me into the right direction?

Thank you very much.

@nagesh That's a very old thread I already visited.
Already did what the most recent answer suggests, with no success.

For MSVC kits, set CDB paths in Qt creator.
For MinGW kits, from my own experience, you need to move the *.dll.debug files from the Qt lib folder to bin folder.

@Alvein Have you tried enabling this option

To get "the source path in the debug information of the executable as reported by the debugger", you can activate the "Use Tooltips in Stack-View when Debugging" option by right-clicking in the Stack View and move the mouse over a specific function call.

Even though thread is old, yesterday user posted accepted answer working fine in Qt creator version 4.14.1 (not sure about mingw/msvc build)

He has installed the sources when installing Qt via the online installer

Set them to what?

I don't need to see tooltips. I need to get the source code, not a disassembly.

And that didn't work and that's why I created this question.

See my attached pics.

Add Qt bin folder (where the .pdb files are located) to Symbol Paths.
If you want to step into some plugins' source code, also need to add those plugin folders (because their .pdb files are not located in the bin folder).

@Bonnie I did this
Qt-5.15.2-debug-CDB.PNG

The folder C:\Qt\5.15.2\msvc2019\bin has all the Qt5*.pdb files.

Is that OK?

Because it does not work either.

What does that note mean?

@Alvein Seems that some Source Paths Mapping entries are missing.
Try to remove the existing ones, and then click "Add Qt sources.." again.
I have four entries in my qt creator.

@Bonnie That made it.
I just needed the c:/users/qt/work/qt target, though.
And no CDB paths at all.

I'm pretty sure I used the Add Qt sources button before, but ATM, IDK (and IDC) about what happened.

Thank you very much!
I've been on this for a long while.
