/* How the resize system works:
First, you need to add a WWT_RESIZEBOX to the widgets, and you need
to add the flag WDF_RESIZABLE to the window. Now the window is ready
to resize itself.
As you may have noticed, all widgets have a RESIZE_XXX in their line.
This lines controls how the widgets behave on resize. RESIZE_NONE means
it doesn't do anything. Any other option let's one of the borders
move with the changed width/height. So if a widget has
RESIZE_RIGHT, and the window is made 5 pixels wider by the user,
the right of the window will also be made 5 pixels wider.
Now, what if you want to clamp a widget to the bottom? Give it the flag
RESIZE_TB. This is RESIZE_TOP + RESIZE_BOTTOM. Now if the window gets
5 pixels bigger, both the top and bottom gets 5 bigger, so the whole
widgets moves downwards without resizing, and appears to be clamped
to the bottom. Nice aint it?
You should know one more thing about this system. Most windows can't
handle an increase of 1 pixel. So there is a step function, which
let the windowsize only be changed by X pixels. You configure this
after making the window, like this:
w->resize.step_height = 10;
Now the window will only change in height in steps of 10.
You can also give a minimum width and height. The default value is
the default height/width of the window itself. You can change this
AFTER window-creation, with:
w->resize.width or w->resize.height.
That was all.. good luck, and enjoy :) -- TrueLight */
