I was going to ask how to hack a resizeable color layer, but I think I
managed to patch it together just by guessing. I needed this for
creating a visible box for in game selection.
class ResizeableCL(ColorLayer):
# resize is called from on_mouse_drag
def resize(self, dx, dy):
self.width += dx
self.height += dy
def draw(self):
x, y = self.width, self.height
ox, oy = 0, 0
self._vertex_list.delete()
self._vertex_list = self._batch.add(4, pyglet.gl.GL_QUADS, None,
('v2i', ( ox, oy,
ox, oy + y,
ox+x, oy+y,
ox+x, oy)),
'c4B')
glPushMatrix()
self.transform()
glPushAttrib(GL_CURRENT_BIT)
self._batch.draw()
glPopAttrib()
glPopMatrix()
It seems to work for me, looks good and responsive. Is it correct way of
doing it?
