Here when I press the button, make a new list , it takes me to the first screen. And if I use the back button from there, the application does not close immediately, even though I managed to close it without pressing this button.
Also something else I find wrong with this list.
It does not delete the checked purchased products so that only the ones that were not purchased remain.
Delete purchased products completely and keep only those that were not purchased, to complete the list for a subsequent purchase, only with those left out of the market ShopingLista_checkpoint1.aia (62.8 KB)
Well, it is so difficult if you change the blocks without understand what are you doing...we are repeating the same errors once and again...I told you that didn't store anything new in tinyDB, nor checkboxes news....Regarding to keep the pending products...it is not an error...it is not implemented...I share you a modified aia, with the correct buttons to switch screens and to close the Screen1 i back pressed.
It also has the moficication to keep the pending products in the list. Check it.
Unfortunately, my knowledge about them is minimal. That's why there is this naivety of stock code, but mostly the not easy understanding of it all.
One thing is for sure, I'm trying.
And my last attempt at this whole multiple virtual screens thing. Add the list to the 3 remained virtual screens.
Thanks for the help.
With these 2 things you can create whatever you want in your UI without restriction and dynamically.
Example, I am working on an application where these 2 components are essential, because I call absolutely all my UI from a database.
In my screen i only have a Row Layout as an AppBar, other Row Layout to View Pager and a Column Layout to handle the OnPageChanged event.
So... i call from my DB all the Options Titles that act as screens
Create the View Pager in Horizontal Arrangement
For each Title [News, Weather, Professionals, Appontments, etc] create a view on the view pager.
On the OnPageChanged event, im use the Vertical Arrangement to show al the sub options created with the Dynamic Components
And from there the rest of the logic of your App.
You can create a new window with another Pager and pass parameters to it, etc.
That way, directly from my database I manage the entire UI in realtime (Labels, Buttons, Images, icons, Spaces) and their respective parameters [Height, Width, Color, Padding, etc.]
It does not necessarily have to be a database, as it could well be a csv list, dictionary, list, etc.
The point is that to appreciate its true potential, it is better to do it from a cloud database.
Thanks, I'll look into it all.
For now I'm learning here by putting the shopping list with 3 real screens into another app with 13 virtual screens.
So far with the help of the guys in here I managed to put 10. And today a last one came up with 3 real screens.
Extremely difficult for me, because there are buttons that lead to real screens, and now I have to find a way for them to lead to the virtual screens
Come on! ...don't let your spirits falter, you're already close to the goal. Remember that the buttons to go from one screen to another must now "hide" and show the arrangements.
But like Ron Damon say: "...don't let your spirits falter..." everything teach you something.
Today it is an App with 17 screens, but tomorrow... optimization (we always end up optimizing)
And here we will be too... Also saying: "...don't let your spirits falter..."
but in a dynamic way
