Qt Creator 16 displays indentation incorrectly

ronperek · 24 Apr 2025, 11:45

Recently I noticed that indentation in my project was broken. Realized that the file has not changed, but it's only the Qt Creator that displays it differently. Not 100% sure, but I think it happened in version 16.

Piece of code:

	uint32_t	analogOutput___source	[ANALOG_OUTPUT_COUNT];
	float		analogOutput___rangeMin	[ANALOG_OUTPUT_COUNT];
	float		analogOutput___rangeMax	[ANALOG_OUTPUT_COUNT];

How it is displayed correctly in xed (and previously in Qt Creator):

How it is displayed now in Qt Creator:

Is there some option I can change to get back to the previous display, or do I need to wait for a fix?

@ronperek
It may be a genuine problem in Creator 16, but have a read through recent https://forum.qt.io/topic/161687/indentation-issue-on-qt-creator. There were still some unanswered questions at the end of that?

@ronperek
I don't know how relevant/if it helps, but it looks like 16 has indeed undergone some indentation code/behaviour change per https://www.qt.io/blog/qt-creator-16-beta2-released.

Did you try searching the bug forum?

ronperek · wrote on 24 Apr 2025, 12:52

Yeah. I found few issues related to indentation, but nothing exactly like my issue. I'll report this bug there. Thank you for help.

JoeCFD · wrote on 24 Apr 2025, 12:59

@ronperek It may be better to select "Spaces only" for Default tab policy. Otherwise, your code may not be displayed well from command line.

ronperek · 25 Apr 2025, 06:58

Tabs worked fine for me so far. I don't like moving the cursor through all the spaces instead of 4x fewer tabs.

JonB · wrote on 24 Apr 2025, 13:47

In the good old days when tabs stops were always every 8 spaces under Unix at least it all worked fine. Nowadays with the ability to change what tabs mean per language/file and the mixing of spaces and tabs I often find tabbing a mess and sadly it's easier/more consistent to always put in spaces.

@ronperek said in Qt Creator 16 displays indentation incorrectly:

I don't like moving the cursor through all the spaces

You can move cursor word-wise by using CTRL-left_arrow and CTRL-right_arrow

ronperek

Looks like this is only the issue for display. I noticed block selection works correctly acting like the elements after tab are in single column when initiating selection.
