How to set certain item in BOLD in a listbox?

[Grace]

Hi all,

How would you change the font or set the item text in bold in a listbox in win32? I've been digging around, and couldn't find anything in win32.

Thanks in advance,
Grace

I think it's an all-or-nothing type of thing. You could send the listbox a WM_SETFONT message, but that would affect all items.

If you want to bold a particular item, you'll probably have to use owner-drawing. Specify LBS_OWNERDRAWFIXED or LBS_OWNERDRAWVARIABLE (if the height of your items is not the same) and draw it anyway you want.

Hi Bond,

Do you have any sample code for Owner-Drawing to accomplish this?

Thanks,
Grace

Take a look at the CColorListBox::DrawItem method. This will give you an idea.

depending on your condition, you may simply need to maintain 2 fonts. One a non bold font and other a bold font.

In the DrawItem you just need to select the proper font to the DC before you call DrawText .

I am having problems setting and retrieving the text.
From the parent of the listbox, I do

SendMessage(HwndListBox, LB_ADDSTRING, 0, (LPARAM)"someText");

I don't see any text.

In the WM_DRAWITEM of the listbox callback function, I couldn't get text by doing

TCHAR sText[256] = {"\0"};
SendMessage(HwndListBox, LB_GETTEXT, lpDIS->itemID, (LPARAM)sText);

That's from the MFC code.
CString sText;
GetText(lpDIS->itemID, sText);

Any Idea?

Hm.. if you do not use owner draw style i.e. a normal list box, do you see the text appear. Just to make sure that at least that part is working fine.

I figured it out.
It should be SendDlgItemMessage(hwndParant, IDC_LIST1, LB_GETTEXT, lpDIS->itemID, (LPARAM)sText);

Thanks for all of your help, guys! You two are awesome!
