Problem about transfer value and combobox at wxPython - image

Question

Hi I'm wxpython newbie.
and an week before I was upload my question and not yet solve.
so Today I need more help about my problem
so here is the code....

imageno = row[3]
# -- IMAGE
erim = Image.open('./image/image_error_ramp/%s.webp' % imageno)
erim.info.pop('background',None)
erim.save('./image/image_error_ramp/%s.gif' % imageno,save_all=True, loop=0)
anim = Animation('./image/image_error_ramp/%s.gif' % imageno)

ctrl.Play()
os.remove('./image/image_error_ramp/%s.gif' % imageno)
if __name__=="__main__":
app = MyApp(False)
app.MainLoop()
and progress of this code is below
input "model name" at textctrl
search "relate model" and button bind to event (to get a specific model name)
select a "model" from listctrl bind to event (to get a combobox's elements)
and combobox's list fill with relate list (list's element bring from sqlie)
select a combobox element and relate image is shown (image is animated GIF)
and below is my problem
when I select combobox list and Animated GIF is played at panel.
and select combobox's another element, Animated GIF play another and image is overlap
below code...image convert and play code... i call this code "IMAGE"
(I saved all Animated GIF to webp and convert to gif that time)
erim = Image.open('./image/image_error_ramp/%s.webp' % imageno)
erim.info.pop('background',None)
erim.save('./image/image_error_ramp/%s.gif' % imageno,save_all=True, loop=0)
anim = Animation('./image/image_error_ramp/%s.gif' % imageno)
ctrl = AnimationCtrl(self.Panel_err_image, -1,anim, pos=(35,40))
ctrl.Play()
os.remove('./image/image_error_ramp/%s.gif' % imageno)
So I think maybe Solve the problem to move "IMAGE" code locate below the constructor code(because init constructor is there.)
# constructor
def __init__(self, parent, id=wx.ID_ANY, title="Search", pos=wx.DefaultPosition, size=(1500,650), style=wx.DEFAULT_FRAME_STYLE, name=""):
IMAGE CODE
and here(below the constructor code) I can't get imageno (imageno is image's name. and this name bring from sqlite, so I select a element from a combobox but I can't get any response from combobox)
and my problem is this
Can I get the image's name from the sqlite at the below of constructor code with combobox?
or otherwise at original location(below the annotation "IMAGE") any code for "Animated GIF not overlapping" ?
ps. week a go robin dunn and rolf of saxony teach me about this problem
But I can't Understand and very depressed.....
Have a Niceday

Answer 1

It's quite difficult to know where to start with this answer, because there are coding errors, logical errors and I do not know what the data looks like.
However, several things stand out.
sqlite queries need a fetch to return the row/rows
use fetchone(), fetchmany(n) or fetchall()
When testing print() is your friend, if not using an IDE
print the result/s to check you have what you expect
Always assume that an error could have happened, test with if or try for example
Initialise variables, especially if you are setting them in an if statement
Assume the test could fail.
That said, I applaud your go for it attitude but you could have done this in smaller steps. Master each step before attempting to put them all together.
Here is a version of your code, that comes with many caveats.
I don't know your data or data structure.
I have started by creating some dummy records in my database.
I don't know your objectives or the logic.
Only those issues I needed to address to get a basically functioning program have been addressed and I've removed some code around the image processing to help me not you.
Hopefully, you can find some benefit in the code below.
I recommend using "diff" on my code versus yours, to see what has changed.

# Define a default data

MyCate = cur.fetchone()
