Hello!
This is my first post in this group and the reason why I came across here is
that, despite my complete lack of knowledge in the programming area, I received
an order from my teacher to develop a visually interactive program, until 20th
July, so we can participate in a kind of contest.
My goal is to learn and program it by myself, as good as the time allows me.
That said, what I seek here is advice from people who definitively have more
experience than me on topics like: is it possible to develop this kind of
program in such a short amount of time? What kinds of aspects of Python should
I focus on learning? What tutorials and websites are out there that can help
me? What kind of already done packages are out there that I can freely use, so
I do not need to create all the aspects of the program froms scratch?
It would be wise to give an abstract of the program. I made an information flux
kind of graphic, but I do not know how to post it in here, so I'll use only
words:
Full screen window
Do you literally mean a full screen *window*, like a browser maximized,
with frame and title bar with Minimize, Restore/Maximize, and Close
buttons? or a full-screen app without the frame, like full-screen games?
Tkinter, Wx, etc, are meant for the former, Pygame, etc, for the latter.
-> Title and brief introductory text -> 3 Buttons (Credits)
(Instructions) and (Start)
(Credits) -> Just plain text and a return button
(Instructions) -> Just plain text and a return button
(Start) -> Changes the screen so it displays a side-menu and a Canvas.
If you open Idle and click Help / About IDLE, you will see a dialog box
with title, text, and two groups of 3 buttons that open plain text,
including Credits, in a separate window with a close (return) button. It
you decide to use tkinter, this would give you a start. The code is in
Lib/idlelib/aboutDialog.py. I do not know how to make the 'dialog' be a
main window instead, nor how to replace a main window with a new set of
widgets (as opposed to opening a new window), but I presume its
possible. If so, I am sure Rick could tell us how.
Side menu -> X number of buttons (maybe 4 or 5)
Is this really required, as opposed to a normal top menu?
Buttons -> Clicked -> Submenu opens -> List of images
-> Return button -> Back to side menu
Image in List of images -> When clicked AND hold mouse button -> Make copy
I am not sure what you mean by 'copy'. Make an internal image object
from the disk file?
-> if: dragged to canvas -> paste the copy in place
-> if: dragged anywhere else -> delete copy and
nothing happens
It sounds like the intention is to have multiple images on the canvas at
once.
On canvas:
Image -> On click and drag can be moved
This could be a problem if images overlap.
-> Double click -> Opens menu -> Resize, Deform, Rotate, Color,
Brigthness, Contrast, Color Curve, Saturation
Image operations are what are usually placed on a size menu or floating
menu box.
Neil mentioned PIL (Python Image Library) because Tk's image support is
anemic, and does not have any built-in transformations. Pillow, at
https://pypi.python.org/pypi/Pillow/2.0.0
is a friendly fork that include patches to run on Python 3.3, which I
would otherwise recommend that you use.
Then, somewhere in cavas:
This should be a button on the side menu.
Save option -> Prompt for file and user's name
-> Prompt if users want printed copy or not -> Print
-> After saved, display random slideshow in other monitor, device
or screen with the users' creations.
