I want to ask is it possible to update the output manually while using interactive_output?
the function I'm currently using is pretty complicated, so the output kind of lags a bit when the slider widget is used.
much thanks!

I'm trying to achieve something similar to the image below. I'm pulling some data from Firebase to generate the content. Is this possible to achieve with a ListView or am I better off trying to slap something together using Columns, Rows, and some functions? I already have the skeleton for design purposes done. But, just curious if you can do this with a ListView or something similar somehow?
I've tried searching and couldn't really find a good answer.
I'm looking for a way to create a logic color drawing like fill tool in photoshop or gimp or event paint...Here is basically what I want to implement :

Any suggestion on how to do that ?
Sounds/looks like you just need to implement a flood fill algorithm. There a few variations, from simple 4-direction to more complex 8-direction, though all work on a similar principle and are fairly easy to implement.
Here's a link to a GameDev.SE post that may be a good place to start and perhaps even a better place to post this question!
You can implement the flood fill algorithm
How can I integrate a Scrollwheel into my application?
I'm currently using Sliders but have found them to be sometimes difficult to control exactly (for example with a linear scale from 0% to 100%). I guess they weren't designed for that purpose and are meant to be used for cases where not pitch perfect control is ok (Volume Control and the likes). However, I really need an exact way of inputting data (other than TextFields, they won't work in my case).
I figured that a Scrollwheel kind of UI Element would be perfect for me. Are there any opensourced Scrollwheels available that would fit my needs?
Horizontal, just like Sliders
Variable Start and End Values
Variable Scale
Small in height
Pretty :)
I tried using the Picker but that didn't work for me since it shows it's values inside of it, which makes it both big and not pretty to look at when used multiple times inside of one View.
If there's nothing available that fulfills my needs (described above) could someone please give me a hint on how to start effectively with creating such a UI element? Thanks!
I've finally found something which fits my needs :)
OBSlider, a subclass of UISlider which allows variable scrubbing speeds – it imitates the behavior seen while scrubbing in iPod.app.
Fulfills all my needs:
Horizontal
Variable Start and End Values
Variable Scale
Small in height
Pretty :)
I want to implement an UI which should look like Speedometer. Is there a way to implement like that? Some of apps i seen that they have implemented. For ex. an app called "TaxCaster" implemented it. Could someone help me how can i achieve it?
Thank you in Advance.
That is possible yes, but it will not be easy. You will have to either use OpenGL or Core Animation. I would suggest the latter if you want something like they have in TaxCaster.
You can find more about Core Animation here.
I hope it helps.
A possibility is to simply have two UIImageViews:
A background that has all the measurement listings (i.e. the ruler part), and another that would act as your needle, pointing to the current measurement. All you would need to do when changing the current measurement would be to use the transform property to rotate it into the correct position.
Not a trivial amount of work, but it shouldn't be too hard.
i am trying to make a Kaleidoscope app in iPhone.
Some one can tell me how can make it, what kind of techs i must use, please !
thanks a lot for your helps, i am so worried now !
Thanks
To generate a random background and then do the two mirror reflections, you will need CoreGraphics/Quartz, and know about layers, and CGContexts. In order to vary the background based on the movement of the iPhone, you need to learn how to read the accelerometer.
This is if you want to make it look similar to a real Kaleidoscope. Otherwise you could take the much simpler approach of creating a graphic formulaicly based on random data that is then cropped to a pie slice and repeated twice to create a simple Kaleidoscope graphic.
