|
Description :
For a GUI, controlling layout (especially on resize) can be difficult,
especially if your layout is complex. When looking at a GUI, I came to the
realization that I could express the layout nicely like this:
AAAAAAAAAAAAAAAA
BBBBxxxxxxxxxxxx
BBBBxxxxxxxxxxxx
DDDDDDDDDDDDDDDD
DDDDDDDDDDDDDDDD
DDDDDDDDDDDDDDDD
%%%%%%%GGG
Where each group of contiguous, like characters specifies a screen region.
*Very important*: space is not legal. Nor should you use \"-\", trust me. A
space (\" \") will cause you to die, but a \"-\" is accepted, but is used by
other modules for other things. BEWARE!
To me, this gives an easy-to-grasp pictorial of the GUI layout, as long as
one notes WTF the letters and symbols represent. The only caveat is that
the collection of like characters/symbols making the pattern must be
adjacent, and must be rectangular. And the overall pattern must be
rectangular.
Note that this textual arrangement can be as big as you want. It\'s all
relative. Although it might not look like it on the screen in your editor
of choice, all spacing is assummed to be the same in X and Y. Thus, the
aspect ratio of the above pattern is 16/7 (width/height).
To be useful for a GUI, one must be able to map this goofy space into
screen coordinates. That\'s what the *map_range* function is for (see
below).
Now, I know what you must be thinking: is this guy nuts? Why not use
brand-X fancy GUI layout tool? Well, the fact is that those are nice and
easy for the initial layout, but they generally generate code with precise
XY coordinates in them, which makes resizing almost impossible.
The idea here is that we use the above textual layout to specify all the
relative positions of things, then map this to a real coordinate system,
preserving the spatial relativity and size associations.
I wrote this for use in a GUI application, but figured it might have use
elsewhere. Hence, this class. If you find a novel use for it, please let me
know what it is (email address in this document).
