Is there an easy way (or any way at all) to specify fonts for the individual
elements in a Open Look Scrolling List widget? Can you set background colors
for the individual elements? I'm writing an application that I need to
have certain elements in a scrolling list highlighted in some way. Is this
possible?
Thanx in advance,
Ken

You don't say which Open-Look toolkit you're using. For XView, try
setting the PANEL_LIST_FONTS parallel list. Truncated parallel lists
don't work for this attribute, and the single PANEL_LIST_FONT may or
may not work (can't remember if its buggy or not).

Not that I know of (but that don't mean a whole lot ;-).

Is this >possible? for fonts use the attribute: PANEL_LIST_FONTS, font1, font2, ..., 0, I'm not sure about "highlighting" an item, but you can "select" it: PANEL_LIST_SELECT, row, boolean, follows is some code.

Unfortunately, in OLIT, you cannot set individual fonts or background colors for ListItem strings(good "Request for Enhancement" though!). (though you *May* be able to use the glyph to get some color accent) If you look at the structure for the ListItems: /* From ScrollingL.h...*/ typedef struct _OlListItem { /* OPEN LOOK list item */ OlDefine label_type; XtPointer label; XImage * glyph; OlBitMask attr; XtPointer user_data; unsigned char mnemonic; } OlListItem; This shows what attributes you can set on individual ListItems. You can set an item to look 'selected' using the attr field (and you can have multiple, disjoint items selected at once - in 3D they will looked depressed). Below is a code fragment which shows how to set this.... (You probably should consult the docs to better understand all the code - it is sort of obscure). OlListToken token; OlListItem *item = OlListItemPointer(token); void (*ListTouchItem)(); /* Get handle of update routine...*/ XtVaGetValues(scrollinglist, XtNapplTouchItem, (XtArgVal)&ListTouchItem, NULL); /* * Mark the item as selected or current by setting a bit * in its attribute field. Notify the widget that we have * touched an item. */ item->attr |= OL_LIST_ATTR_CURRENT; /* set current attr */ (*ListTouchItem)(scrollinglist, token); /* tell list */ Hope this helps somewhat.
