- Can't wait for those News/ftp archive CD's to come. :-)

- I've been fiddling with NXSplitView by placing two views as subviews and
- then placing a label in the corner using PSshow() and PSmoveto().
- Unfortunately, the text comes out backward/upside down. I thought that
- this was caused by the flipped orientation of the split view but the
- vertical placement of the text appears to be proper for the locations I am
- indicating, that is, the subviews of split view don't have flipped axes
- also.
-
- How do I flip the text again? A code snippet is below. The problem does
- not appear to be caused by the split view's flipped vertical axis since
- the subviews have properly oriented axes. This method belongs to the
- subview class that are under the split view:
-
-
- -drawSelf:(const NXRect*)rects :(int)rectCount
- {
- NXRect aRect=rects[0];
-
- NXDrawGrayBezel(&aRect, NULL);
- NXSetColor(theColor);
- NXInsetRect(&aRect, RECESSWIDTH, RECESSWIDTH);
- NXRectFill(&aRect);
-
- // add the text
- PSsetrgbcolor(1.0, 1.0, 1.0);
- PSmoveto(10.0,NX_HEIGHT(&aRect)-10.0);
- PSshow(label);
-
- return self;
- }

- You should do your text drawing with a TextFieldCell or a Text object.
- It's a little slower because of clipping (although I suppose you could
- turn that off), but a lot less hassle and you get other benefits (e.g.
- your app will draw Kanji glyphs when run on a Kanji system, whereas apps
- that issue raw PostScript to generate text will not "just work").

- This is crude because the font should be newFont'd somewhere else, but you
- should get he idea. The fontMatrix can be the identity (for non-flipped views
- like yours) or NX_FLIPPEDMATRIX for flipped views. Have fun!
