04:24

Grrr.... what does enumerate do?

KronoS

04:35

ok i think i got it.. but this doesn't make sense!

KronoS

05:06

@IvoFlipse when you get up... go ahead and give me a 'ping'... need your help

KronoS

06:05

OK @IvoFlipse I'm going to head to bed for a little while and try to get up around 4 my time (in about 5 hours)....

Here are somethings that I need a tutorial on:

1. manipulating buttons (mainly trying to figure out how to fit them all)
2. Manipulating text (trying to add text either above or below the buttons
3. How to parse data and function to each other (in other words how to use the pubsub)

ok I think that it for now... I'll talk at you in a few hours

just pushed all my work thus far...

doesn't know how he's going to do it... but won't give up now...

Sergey

09:13

interesting name of the room

Ivo Flipse

thank you @Sergey ;P

I'm working on becoming less fake every day

Sergey

09:46

we all do

Ivo Flipse

yeah, but some at least have a CS degree :P

Sergey

which I assume means that you don't?

Ivo Flipse

nope :)

I made the mistake of thinking Human Movement Science being an actual trade

ahd you?

Sergey

10:13

I'm a third year, I have no idea how it's called(after freshman, sophomore...?)

KronoS

12:00

@Sergey that would be Junior... then Senior... at least in the U.S. that is... not sure where you're from'

mornin @IvoFlipse

Ivo Flipse

hi @KronoS

KronoS

hey... still trying to wake up :P

Ivo Flipse

no problem

so manipulating buttons: you want to make sure they fit the resolution?

KronoS

@IvoFlipse yes

That's my biggest concern, and there's two different types of resolutions that I have to deal with. It would be nice to have it dynamically change (if possible)

Ivo Flipse

well we don't have to arrange them in long lists, we could also make squares

'dynamically' as in check the resolution on start up and use a different layout I hope?

KronoS

12:14

@IvoFlipse well the long lists work with the exception of one list... and that's on the regular resulution... on the 'long' resulution the length is fine, but the width isn't

@IvoFlipse yes that's what I'm thinking

Ivo Flipse

ok, why not hardcode a length of X

KronoS

- make sure that the button 'fit' to the window...

Ivo Flipse

is it get's longer than that, split the list in half

KronoS

that sounds good to me... I think that we need to make the button smaller as well...

Ivo Flipse

you're getting an error on startup right?

@KronoS I was about to look at it

KronoS

12:16

@IvoFlipse I don't think so

Ivo Flipse

I just got the primary key error

KronoS

no... no errors.

Ivo Flipse

oh right

KronoS

@IvoFlipse you have to delete the db

Ivo Flipse

that's because you're trying to insert data that already exists

KronoS

12:17

I was going to code that whenever I press the 'close app' button it would delete the file, but I ran into issues with that...

Ivo Flipse

@KronoS no, what you should do is let it try to select from the table

if there's something there: you don't have to insert :)

KronoS

'select' as in view?

Ah:

> The SELECT statement is used to select data from a database.

> The result is stored in a result table, called the result-set.

is there a way to word wrap in eclipse?

Ivo Flipse

sending an update

I think we can make the buttons 50% smaller

if we just make it toggle start/stop

KronoS

it should fit if we do that

Ivo Flipse

crap I don't know how many rows/cols it will have :\

though looking at the loop

I'm calling all these sizers up front

I think I can do that in the first 'layer' of the loop

KronoS

12:26

what does the if not statement do?

oh and can we use the massive list that's in the databasebuild model for building the button in tasktrackerpanel? or is that just too complicated?

Ivo Flipse

@KronoS if there's no result from the select statement: insert data

@KronoS then you need to put it in a different file

which we can parse

I'd say: we'll change that later

KronoS

ah makes sense... or in other words 'if null'

@IvoFlipse sounds good to me

Ivo Flipse

woops forgot to add the labels

KronoS

uh... ew... :P

lol

Is there a way to 'box in' the different categories?

Ivo Flipse

That was what I was trying to do

KronoS

12:35

that's better... the columns are so squished though....

and how did you do that? I was tyring and trying last night and couldn't figure it out

Ivo Flipse

@KronoS that's because I didn't state how wide they should be

push on its way

darn, I want the label of the button to change to Stop when its active

KronoS

lol that's what I was about to ask :P

Ivo Flipse

nvm I just added that to the togglebutton function

self.SetLabel = 'Stop'

now to make the columns wider

KronoS

that can be done with the 'todggledbutton' def

Ivo Flipse

and add more space

each button is 50 pixels, they all get 5 pixels vertical distance

so we can 'estimate' what the maximal amount of buttons would be

I'm spoiled with my 22 inch screen, not ever computer uses that

the list should definitely not get any longer than 10 (which is intervention+1)

btw pushed the changes again

KronoS

12:51

made some changes as well... sending a push

Ivo Flipse

ah you added a new database?

KronoS

time to pull out the new lappy and see how it looks :)

@IvoFlipse no I added some icons to the Options page...

Ivo Flipse

ah I thought I saw something jump

is it options or Settings? ;)

KronoS

settings :)

good call

Ivo Flipse

so now to make things active

we need to set a location

we need to pick a subject

we need to start an observation

where do you want to do all this?

KronoS

13:00

just a sec....

this is what it looks like on the tablet :(

minus the keyboard below

Ivo Flipse

@KronoS ok, let me change one thing

KronoS

is there a way to have smaller lists below each other?

Ivo Flipse

I added a print statement to mainframe

which prints x, y

so we know what shape it will make the screen

KronoS

well the screen is 800x1280 if that's what you're looking for...

Ivo Flipse

I just meant, we can use that check to determine how to lay it out

KronoS

13:06

Ah.... ok....

Ivo Flipse

Why not rotate the tablet screen? ;P

The current way the buttons are laid out is by creating one horizontal sizer

and just sticking all sizers next to each other

we could add a check: if len(buttonlist) < 5 --> add the next below it

wiki.wxpython.org/wxGridBagSizer

KronoS

Hmmmm....

Ivo Flipse

or we need to make a gridsizer

where each row = 5 buttons long

:\

zetcode.com/wxpython/layout

the explanation for a gridbagsizer is near the end

KronoS

what about this one:

>wx.FlexGridSizer

This sizer is similar to wx.GridSizer. It does also lay out its widgets in a two dimensional table. It adds some flexibility to it. wx.GridSizer cells are of the same size. All cells in wx.FlexGridSizer have the same height in a row. All cells have the same width in a column. But all rows and columns are not necessarily the same height or width.

Ivo Flipse

that's the problem, everything has the same size more or less

btw that's already being used ;)

the label + buttons are in a flexgrid

each sizer is 51 pixels wide

KronoS

13:16

oh....

Ivo Flipse

based on the longest name I reckon

so the max width we have was 800 pixels?

KronoS

this statement kinda scares me:

> The most complicated sizer in wxPython. Many programmer find it difficult to use. This kind of sizer is not typical only for wxPython. We can find it in other toolkits as well

Ivo Flipse

so what we first need to do is make sure everything moves to the left

as to not waste width right?

oh wait nvm

the sizer aligns itself with the center of the screen

KronoS

ok...

Ivo Flipse

that was the problem

KronoS

13:18

yep

Ivo Flipse

we can only see 4 lists at a time (with some room to spare, but not enough)

we have 7 lists, so that's nice

one issue is: you shouldn't have interventions + non-clinical tasks

that would be huge

but you can't put interventions on the far left either

it needs to be somewhat chronological

what we should do is detect the aspect ratio of the screen

or well we can calculate it, but I reckon we're going to need it EVERYWHERE

stupid non-rotating tablet

btw your battery is half way out :P

when the aspect ratio is W<H instead of a horizontal sizer, use a flexgridsizer

KronoS

so when it's run width wise the buttons fit just right...

Ivo Flipse

(1680, 1050, 1)

oh right, f-ing integers :P

(1680, 1050, 1.6000000000000001)

that's better

KronoS

what's that?

the 1.6

Ivo Flipse

the aspectratio

KronoS

13:26

oh...

lol :)

if it's less than one then W<H

Ivo Flipse

yeah, I just added the check

so try it on the tablet

(don't forget to pull)

KronoS

interesting....

so it aligns left, but if I 'maximize' the window it aligns center...

Ivo Flipse

what doe sit do

KronoS

still doesn't fit

Ivo Flipse

show me the money

KronoS

13:34

newest edition

Ivo Flipse

what aspect ratio does it show?

KronoS

you mean on the console?

it doesn't... it only show (800, 1280)

Ivo Flipse

oh right, I removed that line, well I calculated it myself

check with that tool, what kind of sizer its using there

it shouldn't have more than 5 columns :\

KronoS

what tool?

Ivo Flipse

on MainView, the one that's commented out

#wx.lib.inspection.InspectionTool().Show()

KronoS

13:43

oh right... so I have it pulled up but not seeing where it says whether it's a flex ornot

oh found it... it is flex gridsizer

Ivo Flipse

what details does it have?

cols/rows

KronoS

a lot!

lol... checking

Ivo Flipse

oh I spot a mistake

rows+cols are wrong

that's a start

on tasktrackerpanel: self.buttonsizer = wx.FlexGridSizer(rows=2, cols=4, vgap=5, hgap=5)

I had rows=4

but we want 2 rows and 4 cols

KronoS

oh wait... so i think you have the flex sizer within a box sizer within a boxsizer within one mote

so it looks like your flex grid sizer is working on the rows and not the columns... that make sense?

@IvoFlipse as far as that goes I have cols = 2

rows = 7
vgap = 5
hgap = 5

Ivo Flipse

yeah that seems wrong

though that may depend on which you click :\

KronoS

13:49

which what i click?

Ivo Flipse

that's the sizer I need details of

it seems to work for me

though its butt ugly

KronoS

mine doesn't do that...

what details do you need?

Ivo Flipse

then that's because the aspect ratio calculation is off :\

new push on its way

we need to rearrange the lists

KronoS

do you want the size? I have (1100, 512)

Ivo Flipse

so interventions and non-clinical tasks are on the top row

buttonlists = [self.data_gathering, self.collaboration, self.interventions, self.nonclinicaltasks, self.outputs, self.documentation, self.idle]

no my latest version should print the aspectratio

some lone number somewhere

oh wait no

KronoS

13:53

this is how we have it in access

Ivo Flipse

I know

yet another fix on its way

I believe it should work now

KronoS

Works!

Ivo Flipse

great :)

it won't be uber flexible, in case you add tons of items to all the lists

but we'll work something out another time

KronoS

ya we just need to get this work for now

Ivo Flipse

so show me what it gives

KronoS

13:59

as a screen shot or outputs?

Ivo Flipse

screenshot

KronoS

brb have to use the men's room

and wake up the wife

Ivo Flipse

There's some ugly space there in the middle :\

hmpf

KronoS

but it works!

Ivo Flipse

indeed :)

so can we now add the other crap?

KronoS

14:05

lol sure! (what crap do you mean?)

Ivo Flipse

so now to make things active
we need to set a location
we need to pick a subject
we need to start an observation
where do you want to do all this?

hi @IgnacioVazquezAbrams :)

you must be lost, you're no fake programmer!

Ignacio Vazquez-Abrams

Hey.

None of the SO rooms look active.

KronoS

@IvoFlipse what do you mean by where?

Ivo Flipse

@KronoS you need to input that info somewhere

so we need to stick it on some panel

KronoS

Ah ok... so I want that to be on the main Panel...

Here's what I see the main panel doing:

Q: How can I speed up an animation?

I'm trying to create a Matplotlib animation of my paw data, where you can see the pressure distribution on the entire pressure plate over time (256x64 sensors for 250 frames). I found a working example on Matplotlib's own site and managed to get it working on my own data. However the 'animation'...

I found a faster method than your suggestion, but it turned out glumpy isn't compatible with wxpython :(

KronoS

1. set all that info

Ignacio Vazquez-Abrams

You could find the deltas and blit only the damaged area.

KronoS

2. ability to change database location

3. change user

Ivo Flipse

@IgnacioVazquezAbrams hmm interesting suggestion, that might actually make it work in matplotlib as well

if that allows it, that is

because the deltas are very, very small compared to the entire array

@KronoS that's not important right now

@KronoS you need to pick a tab to do this on

@KronoS I would do all this on the main tab

we just keep a list of users, then use a list or dropdown to let them pick who they are

KronoS

that's what I was saying... all of those are for the main screen

Ivo Flipse

14:13

@KronoS ah ok, I missed your earlier comment about the main panel

KronoS

:)

Ignacio Vazquez-Abrams

@IvoFlipse Render each frame in matplotlib first and get the deltas from that. Then you don't need to worry about matplotlib supporting it.

Ivo Flipse

@IgnacioVazquezAbrams so I create the imshow(data)

then how do I update imshow with my delta?

Ignacio Vazquez-Abrams

Plot to an in-memory surface instead of to the control.

Then get the deltas.

Then plot the first full frame and follow it up with the deltas.

You'll need to double-buffer the control so you don't have to redraw from scratch on reveal, but it should be fine.

KronoS

Woo Hoo! I added text!

Kronos cowers in @IgnacioVazquezAbrams shadow

Ivo Flipse

14:25

@IgnacioVazquezAbrams does that mean I need to calculate the deltas beforehand?

I'm looking at an example: matplotlib.sourceforge.net/examples/animation/…

> line.set_ydata(npy.sin(x+update_line.cnt/10.0))

that would be the updating of the buffer

Ignacio Vazquez-Abrams

@IvoFlipse Well, you could grab them on first display. But you'll need the images regardless if you want to calculate them.

Ivo Flipse

and after that ax.draw_artist(line) and canvas.blit(ax.bbox)

so the draw_artist doesn't actually update the image yet

blit would be doing that

Ignacio Vazquez-Abrams

If you wanted a Q+D for the delta you could crop both images on blue and just take the larger bounds.

KronoS

Grrr...

Ivo Flipse

what is it?

KronoS

14:35

I seemed to can't get this right @IvoFlipse.. what am I doing wrong?

Ivo Flipse

@KronoS I can't see what you're doing :)

KronoS

oh whoops got both screen on this one :P

I'm trying to get Database Location, Observers, and Session Details to line up horrizontally on top

Ivo Flipse

@KronoS you haven't add them to your sizer

KronoS

@IvoFlipse but I have...

Ivo Flipse

push an update I'll have a look

KronoS

14:40

done :P just did it

Ignacio Vazquez-Abrams

I find it productive to make all my borders decently thick so I know what's where.

Ivo Flipse

@IgnacioVazquezAbrams good point

KronoS

@IvoFlipse I'd like to do that with the taskpanel... but we can do that later :)

so I'm still trying to wrap my brain around the syntax here:

> self.mainSizer.Add(wx.StaticLine(self), 0, wx.EXPAND|wx.TOP|wx.BOTTOM, 5)

what is the 0, and the 5 for?

Ignacio Vazquez-Abrams

You need the C++ wx docs open when working with wxPython.

2

docs.wxwidgets.org/stable/wx_wxsizer.html#wxsizeradd

Ivo Flipse

silly, they all have the same space, so it looks like Observers has a ton of whitespace

KronoS

14:47

can't we have it spread out more evenly across the top @IvoFlipse

Ivo Flipse

I'm trying

but I can't get the labels to be in the center of their sizer :\

KronoS

@IvoFlipse sad... what did you do to change the orientation in the first place?

Ivo Flipse

you made a sizer to put the labels in

but then added the labels to the mainsizer

KronoS

oh I needed to add the sizer of the labels!

D'oh!

Ha Ha! Worked!

now just the spacing... :(
