background color on push buttons

Author	Message
David Gustafsso #1 / 8	background color on push buttons I am trying to set the background color of a push button to somthing other then the default. I have tried several different approches but nothing seems to work. The button simply will not change color. Does anyone know how to do this. I am running VisualAge for Smalltalk version 4.02 under windows NT. I have previously done the the same thing under OS/2 and that worked fine. /David

This is an operating system limitation and is documented in the VAST docs. Windows does not allow you to change the background colors of buttons except through the Display control panel. OS/2 does not have this limitation. We sell a new product called WidgetKit/Controls that includes over a dozen new widgets for VisualAge. One of the widgets is replacement for the standard push button. This widget gives you complete control over foreground and background color as well as support for multi-line labels with images.

In the back of one of the VisualAge Manuals (IBM Smalltalk Programmer's Reference, I believe) there is a table with three columns (Win, OS2, AIX) with a comparison of features and differences between the OSes. Another subtle difference between Win and the other OSes is you cannot make a window non-resizable unless you disable the minimize and maximize buttons. - alexis

Actually, that is not true. Windows itself permits the above just fine. It is a bug/feature of VisualAge that does not allow you to this. My guess is that earlier versions of Windows (2.x? 3.x?) did not allow that combination so the folks at OTI hardcoded that prohibition into their low-level Windows code. IBM really ought to fix this at some point. -Eric Clayberg Vice President Instantiations, Inc., Smalltalk Systems Division http://www.smalltalksystems.com http://www.instantiations.com GO SMALLTALK!

Vlastimil Adamovsk #6 / 8	background color on push buttons There should be a class something like DrawnButton (I don't remember exactly). If you use this, it should help you. Some hacking required, though. Vlastimil Adamovsky Quote: > I am trying to set the background color of a push button to somthing other > then the default.

Some hacking required, though. Actually, it's probably called something like EwqzxlkrDrawnButton to compensate for the non-existent namespace support. :-) David -- ********************************************************************* David Whiteman Applied Reasoning NC State 24, Fla.

Charles Hixso #8 / 8	background color on push buttons That used to be a limitation in Windows Java, and isn't anymore, so I am guessing that you are right about the "cause".
