B4J Library [B4X] [XUI] SD_xComboBox

Something like that. The border more fat :)... I am triying but the border is slim :(.... changing the border in properties

Thank you again @Star-Dust šŸ„°

@Star-Dust, I've spent days looking for this solution, thanks!

- I have found a problem, when the text can be edited, the cursor always moves to position 0, not to the end of the text. It would be convenient in any case, to select all the text to replace it with a new keyboard entry or to leave the cursor in the position that the user pressed.

- An improvement would be to be able to search without distinguishing the upper case from the lower case

Update 0.13
  • Added SetSelection(Start As Int, Length As Int)
  • Added SelectionStart and SelectionLength

With this it works every time the focus changes you can select the cursor wherever you want
B4X:
Private Sub xComboBox_FocusChanged (HasFocus As Boolean)
    xComboBox.SetSelection(xComboBox.SelectedTextItem.Length,0)
End Sub

This is where I see a problem. I don't understand if this is inside your code or if you propose to write it in my code.

My opinion:
'By not having the "if in focus" question, it always returns the cursor to zero position, even when exiting the combo.
Private Sub xComboBox_FocusChanged (HasFocus As Boolean)
  If HasFocus Then
   'How about selecting all? If I want to write again when typing the first character it replaces the entire text.
    xComboBox.SetSelection(0, xComboBox.SelectedTextItem.Length - 1)
  End If
End Sub

You can make the search not "equal to text", but instead the search to be "containing text" and not case sensitive

Update 0.14
  • Added property: SelectOnlyFromList As Boolean

The text search does not only take place for the initial letters but for all the text in the field.
Ignore uppercase and lowercase and finally it is possible to select only from the list or type an element not present in the list with the SelectOnlyFromList command

Hi,

There is currently no solution. When inserted inside an xCLV it is not able to manage the position because the list is already part of a Scrollable View.

Wait for an update that may fix the problem.
