I am trying to set the initial scroll position as I have a floating search bar that will sit above my calendar.
Here is what it looks like on load as you can see the initial date is hidden:
Here is what I want it to look like on start as you can see the initial date is just below my floating search bar:
Anyone know how I can achieve this? Setting the initial start date 1/2 days behind is not an option as the height will vary based on the number of events in those days.
As per the current implementation of the calendar, there is no support to change the initial scroll position. The calendar will be positioned as the initial date view based on the initial display date value or controller display date value.
Please refer to the following UG link for more information.

3 Textfields are aligned in a row.
Awaiting for inputs dd mm yyyy respectively.
On page open, Autofocus on 1st textfield, as input hits 2 digits, autofocus goes to 2nd textfield. As input hits 2 digits, autofocus goes to last textfield with 4 digits.
Users don't need to input '/' or '-'. Only the dates will do.
Age Dialog formed
Does anyone know how to create such a textfield combination for birthdates? Such that when user presses 'Next' Button, a dialog forms which asks user to confirm his/her age?
(meaning that the input from the 3 textfields were saved as birthdates and the output is (today's current date - date input) = age.
Any guidance is appreciated!
You probably want to create one FocusNode for each TextField, then in the validator of your TextFields use a birthdayMonthFocusNode.requestFocus().
You can check more on:
https://flutter.dev/docs/cookbook/forms/focus
Then, you must do a little logic when the user hit the "Next" button.
You concatenate all the TextEditingController().text for each TextFields and using a DateTime.tryParse() you should end with the birthday DateTime of your user in no time. 👍
I added a date and value field to a screen (ZFI_ERWEITERUNGEN_KREDITOR, 0100). Everything looks fine except the fact that no F4 button appears next to the date field. Checking other date fields the F4 button is available.
Does anyone have a clue where this behviour comes from and how can I avoid it?
Problem is solved!
Go to the field attributes in SE51 (Screen Painter):
- Program -> Possible Entries
Choose one value from the drop-down list.
If you have a Range trait setup how do you make it only carry out the change once the user has stopped moving through the range?
ie. some range is changed:
some_trait_changed(self):
wait for user to finish selection
complex calculation.
Every time the user drags the Range tool, it calculates a new value for every single value in the range. I only want it to run once they have settled on a value... i.e. once the mouse has 'unclicked'.
Use Range(..., auto_set=False). The auto_set keyword gets passed to the RangeEditor which will configure the slider appropriately.
It is a little confusing but I will do my best to explain it, I hope it will be fine.
I am trying to create the following functionality in iOS:
I have red button on each row of tableview. The red button is dragged and dropped over the (prototype) tableViewcell and in each row the button will be used. The button text shows the temperature in Fahrenheit. But it changes when tapped so that the color of the button changes to green. And I want the extra functionality at this point; The temperature in Fahrenheit will change into Celcius. (I have the problem on this functionality)
The problem here is that I have a list of tableviewcells (Each is another city), not just one. So I have got that number of buttons and I don't use database to save the temperature data. The data is read through a service and put into an array and transferred to this view by NSUserDefaults.
For example; I have got a list of cities in my tableview. Each is a row and each temperature is put over a red button. Temperature values are the texts of the red buttons.
Berlin 45F
Istanbul 70F
Miami 100F
Chicago 30F
...etc.
So for example, when I tap on the button on Berlin row to change the Fahrenheit to Celcius, there is no problem for the first time so I can get the Celcius value for Berlin, no problem. But when I tap it next time to change it to Fahrenheit again, the value does not come correctly. The Fahrenheit value of Berlin is confused with the other values. Because I don't use a database and it does read the value from an array and it doesn't know which value to use. After some clicks, all the Fahrenheit values come to a single value which is the last city's Fahrenheit value (I use the indexPath.row so it gets the last clicked value)
How can I maintain the temperature data for Berlin without using a database so that when I tap that again after tapping the other cities' buttons, it will show me the correct value (45F or the correct Celcius value)?
Thanks for your help!
While I suggest you use some form of key-based storage (like creating a class "Cities" that stores the temperature, or even storing the city -> temperature key combo in a dictionary), you could read the button text when you click it and convert the value from NSString back to a double or integer.
I assume the function that gets called when you click the button looks something like the one I'm about to write. You can then get the button you clicked and the text it displays like so:
- (IBAction)convertTemperature:(id)sender {
UIButton *myButton = (UIButton *)sender;
NSString *buttonText = [myButton titleForState:UIControlStateNormal];
//...
}
After this, you just convert the string to get the temperature, convert it and display it back.
