1. How do I color in a subfield on a status bar?

I want to be able to address a particular subfield on the status bar, and write to it a rectangular box of my color. What are the functions where it is possible to address a subfield? Can I only write text to a subfield or can I paint to it? Why do I want to do this? To show the currently selected color visually. One thing I am trying is to see if there is a character which is a filled square in some font, and using that. When I attempted to look into a test to display characters, I found that bug in wPuts. Thanks. Andy Katz

However Judith's ColoredButtons can be extended to other controls beside buttons. Although I've never tried anything but buttons. You speak of a bug in wPuts. What bug is that exactly? Don Cole

Don't forget to draw a slightly deflated rectangle, so that the field borders are still visible. 2/ Indeed, your fix for wPuts() addresses the problem. The problem was that, when the text is given as {{text_addr,text_length}}, the lib attempts to compute the length of text_length, which duly fails. 3/ You need to add the SBT_TOOLTIPS style flag to the status bar for it to respond to setHint[Ex]().

But when I placed the code into my parent window in the general section it did not show. So, does this belong in the onpaint for the statusbar? 2 - I was given credit for this fix. See the forum. 3 - placing the SBT_TOOLTIPS did not do anything. Where exactly do I place it in the IDE?

(1) Calculate the location in the status bar where you want the rectanlge to go and use the drawRectangle routine on the statusbar's paint event to place it. (2) Create a OWNERDRAWN status bar. This means that you have total control over what gets placed where in the status bar. But this is not so easy to do. (3) Use an icon. VOID = sendMessage(mySB, SB_SETICON, iPart, hIcon ) where mySB is the ID of the status bar, iPart is a zero based index into which sub field to use, hIcon is the handle of an ICON you have loaded from a file -- Derek Parnell Melbourne, Australia Skype name: derek.j.parnell

I cannot use an icon since the purpose is to show a selected color by the user (yet to be coded). The owner draw idea sounds interesting. But boy do I think of things which cannot be done easily. But then again the whole purpose of what I am doing is to learn as much as possible. But before I do an owner draw, I prefer to find out if I really cannot do it. Also, more important to me is to see the subfields tool tips working, since that is documented as working. Please explain how. Thanks. Andy Katz

Derek has provided changes for Win32lib but for future reference you would place style flags in IDE Property cell Style and/or ExStyle for the control. IDE will not show a separate Hint for each seqment of StatusBar. However if you add controls to StatusBar each of those controls would allow an unique Hint. judith evans

I should have tested before I posted!
