Hi!

I'm trying to have tabs in my CButton/CMFCButton-labels:

C++

CMFCButton *but = (CMFCButton*)GetDlgItem(id);
CString label = _T("Test \t Test");
but->SetWindowText(label);

Instead of tha tab, a rectangle is displayed. I think I found something similar for CEdit-Controls, the problem was solved by using the define BS_MULTILINE.
This does not work for buttons...

I hope someone can help. Thanks ahead.

I do not think you can do this for most Window controls, as they expect the text to be pre-formatted, and do not take any action for special characters.

I agree to Richard's comment. If you really need support for tab characters, you may derive a button class using owner draw to draw the label text.

Seems to me to be a correct solution -- I would up-vote it.

The documentation (http://msdn.microsoft.com/en-us/library/windows/desktop/ms633546%28v=vs.85%29.aspx) specifically mentions this is not possible:

"The SetWindowText function does not expand tab characters (ASCII code 0x09). Tab characters are displayed as vertical bar (|) characters."

This would pass for a decent answer, too.

Moved my comment to this solution to get this question from the unanswered list. Credits should go to Jochen Arndt for the first correct answer.

The documentation[^] specifically mentions this is not possible:

Quote:
The SetWindowText function does not expand tab characters (ASCII code 0x09). Tab characters are displayed as vertical bar (|) characters.

As Jochen Arndt commented you could use owner drawing to implement your own drawing of the button text and so expand the tab characters in the text.

Seeing that all the answers you've received point you to make your own derived button class, I would say that it would be easier for you to see what's already done here in CP, you have a big button resource here: http://www.codeproject.com/KB/buttons/[^].

See the Owner draw area.

From there I've used Davide Calabro job: CButtonST v3.9 (MFC Flat buttons)[^] which can do what you need.

Learning how he have made it or using his code you'll get your desired result.

Good luck. :thumbsup:
