B4A Library [B4X] [XUI] AS Checkbox

Alexander Stolte · Sep 2, 2020

This is a simple cross platform Checkbox.

If you need a checkbox with text, then check out the AS_CheckBoxAdvanced

I spend a lot of time in creating views, like this and to create a high quality view cost a lot of time. If you want to support me and further views, then you can do it here by Paypal or with a coffee.

B4a: XUi,StringUtils,XUI Views (2.40+)
B4i: iXUI,XUI Views (2.40+)

For whatever reason, I forgot to remove a line. Now it should work.

It works

Wonderful alternative to B4XSwitch. I love how it's completely resizable.

When I add text in designer, it doesn't show up in ASCheckbox. Why? Is it possible to somehow add text after the "checkmark"?
I cannot get the index when ASCheckbox is in CustomListView.

B4X:

Sub ASCheckBox1_CheckedChange(Checked As Boolean)
    Dim index As Int = allclv.GetItemFromView(Sender)
    Log(index)
End Sub

I get an error:

B4X:

How can I get the index?

Because the view is only the checkbox, not checkbox + text.
Add a simple label after the checkbox and done.

i dont know what this code does, but it should be this:

B4X:

Sub ASCheckBox1_CheckedChange(Checked As Boolean)
    Dim tmp_checkbox As ASCheckBox = Sender
    Dim index As Int = allclv.GetItemFromView(tmp_checkbox.mBase)
    Log(index)
End Sub

IIf was introduced with B4A 11.0. (Also B4A 9.10 doesn't exist.)

You're right, but even Erel who liked all the posts where I wrote this, didn't notice it. Thanks

- BugFix - When creating the view the CheckedChange event was triggered with parameter "False"

Alexander Stolte · Nov 7, 2021

Update

1.09
- Add Event property - If False then the CheckedChange event is not triggered

This is useful if you want to check checkboxes in the code, but don't want the code to be triggered in the event, because you would then make an INSERT statement, for example.

Nice one but: would it be difficult to expose the top/left etc fields? Sometimes you want to move it programmatically.
