can u help me Out?

@some-user Perhaps I did not understand your post.
If you have your own script and your own UI design, and your script does not work as expected, in this case, as adviced by @JonB , post here your script and your .pyui file.
For this last one, you can share it as gist or rename the file as .txt, edit it, select all, copy and paste here in a post.I'll not be able to help you before this evening...

@cvp sorry for the poor quality, but i had to go fast. So that's my script.pyui. It has a size of 600 x 600. My background is a custom view. I've always used labels in the red circles. In the blue circle I have used text fields so that there can be entered the number of products sold. In the yellow circle is the button that you click after entering the numbers. He calculates it and the result appears in the green circle, which is also a label.
Because it's wrong with me, I thought, I made it wrong. For example, to replace a text field with a label. That's why I asked you. I just copied out the code and used it. If I press Play then this picture appears exactly what you see in my Twitter link. I can enter numbers in the text field, but if I press the button nothing happens.

Turn your phone in landscape mode and then run the original app. The button is off the screen on older phones when they are in portrait mode.

@cvp I can not share this somehow. If I want to save it as a gist error code. I have it now as a file.
-
you need to either post the code (use triple backspace) in the forum, or use share to gist (you can try from the share menu when editing the .py code)
how else do you expect us to diagnose your code? your problem is on line 17, take a closer look at that line...
In general, I will say this:
When you boil down your problem, you have to do three or four things:- get a function to call when you wither update a textfield(maybe), or press OK.
- Get the values of each quantity textfield, and convert to a double
- Figure out which price goes with each quantity, then multiply qty*price, and add up the prices
- update the result textfield
Why not take it step by step:
- can you get a function to call when you press OK? Even just
def ok_action(sender): print('hello world')
If you are using the pyui designer, note that you would fill out the button's action field with, in this case,
ok_sender
. in your script, you need to mKe sure that function def occurs prior to calling load_pyui.-
sender
gives you access to the button- but you need the textfield values... how can you get to the textfields, from the button?
There are two basic ways:
a) you can use sender.superview to get to your main view, then use subviews to walk through the otherviews, or else use the textview names. i.esender.superview['qty1']
, ortextviews = [t for t in sender.superview.subviews if isinstance(t,ui.Textfield) and t.name.startswith('qty')]
where here i have assumed that instead of the default textfield1, etc names, you name your qty textfields as qty1, qty2, etc.
b) alternatively, you can set up a global variable to a list of textfields after you use load_view, then you dont need to use sender at all, just reference the list directly. this is more applicable for more complex ui's.
Before moving on, get your action to print out the value of each textfield to the console. -
This is the tricky part-- how to figure out the price of each textfield... there are a few ways. the easiest is to add a custom attribute to each textfield in the pyui. then you are simply doing
double(t.text)*t.price
to get the price for each item. custom attributes are at the bottom of the ui designer where you set textfield info, and you'd enter something like {'price':1.75} in that field (you enter as a dict, which then gets set as attributes).
If you have the textfields as a list, then you are doing something like
sum([double(t.text)*t.price for t in textfields])
Other ways you could handle this:
a) if you have a textfield names qty1, name your label price1. then you would lookup the label title. -
the last step should be easy if you have understood the steps above. now you are simply setting your result textfield.text. if you understood step 2, you understand how to find the result textfield from sender or from your main view. step 3 gives you the result. then you simple set the .text field of the textfield.
now, take it one step at a time. if you get an error you dont understand, tap Print Traceback, then copy the entire error to paste into your next message.
you really do need to share your code, or we cant help, except in general. try to post your code (from editor directly) - if sharing to gist is giving you an error, post a screenshot of the error!

If you are designing with the pyui, read through the UI docs. It has some good basics.
Then, head over to https://github.com/humberry/ui-tutorial

@some-user You are underestimating yourself, if you take the time to start with very simple examples, you will be able to do what you want. @ccc's example is probably a little advanced -- a good olace to aspire to, but i think you ought to start with ui's containing one button and one textbox, and understand how to read or fill the textbox.
-
@cvp Okay, I have to apologize profoundly to you. Do you know what the problem was? I have not taken a blank script but a script with a UI. I designed my ui and that's why the code did not work. I'm sorry I wasted your time on such stupid problems. Could you please do one more thing for me? And add one more field, in which you can also enter a number. This number is then subtracted from the calculated result. That's the cost of the food needed for the products. https://twitter.com/Someuse79137145/status/1102328019795042304?s=09

@cvp anderen make Sure u got the place :). Thank you https://twitter.com/Someuse79137145/status/1102328791274278913?s=09

I added Ausgaben (expenses) to my solution above.
-
@some-user Sorry to answer so/too late. No problem at all, believe me.
I've made myself so much errors that I'm happy to not be the only one 😂
Welcome in this marvelous app and its marvelous forumEdit: you asked me to add a field but as @ccc already did it, I guess I don't have to do it.
-
@cvp It would be nice if you could do it too. It's very nice of ccc but I can understand your code better. But if they do not feel like they do not have to do it. I would be very grateful.
-
@some-user I write it easily understood but the code of @ccc is more professional and also supports the iPhone. I'll include his additional field this afternoon.

@some-user try this, taken in account dimensions in @ccc code

@cvp Thank you, but there is still a problem. If "Ausgaben" is a number with a comma (for example, 3.33), it will not be considered. I tried to get it myself but it just does not work for me. If you can do that, you must explain that to me.

@some-user You, like me, will need to wait a little bit because my iPad is busy with my granddaughter who is playing Fortnite on it and I'll never dare to interrupt her 😂
