I have some questions about ATK color support. I have been using patch level 6 with color support for a couple of months onan RS/6000 with X-Windows Release 3. I have added some color to one of my applications but I find X paints thecolored window very slow. Is there anything I can do to speed up the colorsupport? In general this is how I set colors: To color a rectangle I do this: myview_SetBackgroundColor(self,self->Color.blockshad,0,0,0); myview_FillRect(self,&oneword,myview_WhitePattern(self)); To draw a rectangle outline in a foreground color I do this: myview_SetTransferMode(self,graphic_COPY); myview_SetForegroundColor(self,self->Color.blockborder,0,0,0); myview_DrawRect(self,&Rect); Is there a faster way of using colors? For any particular window I may setforeground and background colors hundreds of times while painting the window. Is the slow painting due to the R3 X server? I know R4 is faster. Also, Is there a way to set colors on menu cards? on scroll bars? Andy Arhelger IBM Rochester MN

The only way I can see to speed it up would be to not make a call to set the fore- or background color unless the current settings are not what you want: #define myview_ForegroundColor(self) \ self->header.view.drawable->foreName #define myview_BackgroundColor(self) \ self->header.view.drawable->backName #define SetForeground(self,foreground) \ if(strcmp(foreground,myview_ForegroundColor(self)) \ myview_SetForegroundColor(self,foreground,0,0,0); #define SetBackground(self,background) \ if(strcmp(background,myview_BackgroundColor(self)) \ myview_SetBackgroundColor(self,background,0,0,0); Excerpts from misc: 15-Nov-90 ATK Color Support Mark Turner@rchland.ibm.

Scoll bars get the color that is set for the application via the preferences *.ForegroundColor & *.BackgroundColor or through the command-line switches -bg & -fg. Try 'help cmenu' for info on how to set menu colors. Brief synopsis: in ~/.XDefaults add the lines: *MenuBackground: red *MenuForeground: blue There is no programatic way to set the menu colors.
