Setting font in GroupBox

Posted on 2013-11-01
Last Modified: 2015-05-17
The code below used to work in VC++ v6.0. It has stopped working in VS2010, Win 8.
The idea is to set the font of all the controls in a dialog box at runtime.  The code works below works exactly as expected EXCEPT that the font in the group box controls is not changed.  I suppose I could try sub classing  the group boxes but I would rather do something easier.   Don't feel bad, I don't really expect to get a solution here ...

This code is in the OnInitDialog() function:
	CWnd* pChildWnd = GetWindow(GW_CHILD);
	int iCount = 0;
	while (pChildWnd)
		CString sTest;
		iCount ++;
		sTest.Format("control %d",iCount);

		pChildWnd = pChildWnd->GetWindow(GW_HWNDNEXT);

Open in new window

The dialog box was not derived from CDialog,  but from a third party dialog class which apparently does not work "exactly" as expected.  If the dialog box is derived from CDialog, everything works as expected.

Thank you ...

are you using id numbers for the group boxes? or do they have IDC_STATIC as id?

if the latter you may try to change that.

in your test, does the text of the group boxes change by the call of SetWindowText?

if no, the text label of a group box probably has changed to a child window of the group box control. if so, you would need to have a further loop for each control to get their child windows as well. this nested loop also would help to set the font of combo boxes both for the edit and the list part.

I said:
"The code works below works exactly as expected"

If each dialog item did not have a unique ID, this would not have happened.

"the text label of a group box probably has changed to a child window of the group box "

Good Grief!

sorry I missed that comment.

hmm. it was a guess as you stated that the groupbox control doesn't accept a new font for the control. the change you made by deriving from CDialog instead of  a 3rd-party dialog, does not explain why your original code did not work for group boxes. the control would apply the new font if it was a CGroupbox or was derived from CGroupBox beside they added an own paint function or the text part was a child window or they restored the old font after your function. you probably can see with spy what happened.

I have contacted the third party vendor.  They  have admitted this bug and sent a fix.  I have no further need to pursue this matter.
