Re: How to put a caret in a window

Dear Matthew,

> You'll need to set bit 8 in order to make sure the right font is measured

As far as I understand, bit 8 doesn't need to be set if R1 contains the
pointer to the intended font. Anyhow, as you can read in my reply to Pete,
the caret is now basically working.

That is exactly what is next on my ToDo list,
My window has to mimic a writable icon, so it must be possible to click
somewhere in a given string and put the caret there. The only question at
the moment is: How?

I fully agree. For example, since I don't need the y value (it's all about
just one single line), I thought I could forget about the appropriate
register (R4). But no, as soon as I removed the y value on entry, it
immediately affected the x value on exit (which was 0 again).
For a simple soul like me, such logic doesn't immediately spring to mind.

Anyhow, the next challenge is putting the caret somewhere in the middle of
a given string, by clicking the mouse.

Kind regards,
Paul Sprangers
