A little app to display wNim commonly used colors…. forgive any bad code, I
only started learning Nim a month back so feel free to change it, make it
better etc :-)
# Displays a window with all the commonly used wColor constants # Its only been
designed for full screen (1920 x 1080) use, it will not resize if the window is
minimised. # import wNim
type
PanelSize = tuple[width: int, height: int]
# # # How the data is stored in the following sequence: # 1. the wColor
constant... this will be converted to the colours number when read using a
for/in loop, this number is used for the panels variable name (see 3. # below
for notes of why i named the panels this way) and also read again seperately to
colour the panels background # 2. the wColor constant as a string... used for
the text of a StaticText control which is displayed on the panel # 3. a number
used as the variable name for the StaticText control... any number can be used
so long as its not the same as a wColor number, the reason # i used this way is
because the panels that display the wColors as a background and the StaticText
controls are created on the fly and this is the only # way i could find of
creating variable names for them while in the middle of a for/in loop. # NOTE:
Numbers used for StaticText variable names must be higher than 16777215 (which
is the highest number used by the value of a colour constant when its
converted) # IMPORTANT: we could also use DISCARD when creating the controls
rather than storing them in a variable, however that will prevent you accessing
them if needs be.... anyway here is a line showing how to use discard when #
creating the StaticText controls, if you do go down this route then you also
need to remove any lines # that try to access or change the StaticText and you
can get rid of the number used # for the StaticTexts name in the sequence
below... # # discard StaticText(colorConst, label=(colorsTest[i][1])) # # let
