B4A Library Dialogs library

agraham · Dec 7, 2010

This library contains several modal, that is blocking, dialogs by which the user can enter data. Presently they are an InputDialog for numbers and text, a TimeDialog for times and and a DateDialog for dates.

Note that modal dialogs can close unexpectedly and not return to your code if the Activity needs to close, most likely because the user rotated the device. There is a brief discussion of this in the overall library help in the xml. This can also occur with the Basic4android modal dialogs InputList, InputMultiList, Msgbox and Msgbox2 whose modal mechanism is used by the dialogs in this library.

Version 2.92 now posted has a ShowCalendar property in DateDialog that may help newer small devices by suppressing the calendar part of the dialog. However on my Xoom the dialog actually stays the same size but with the date part centred so it may or may not actually help in practice.

I am getting the following error prior in 2.91 and now in 2.92.

Parsing code. 0.12
Compiling code. Error
Error compiling program.
Error description: Unknown member: additem

MyListView1.AddItem("Title #"& i, SomeText.Get(i))
Word: additem

Thanks,

What is the type of MyListView1? Is this question related to the Dialogs library?

Cothek · Apr 9, 2013

Very nice lib here agraham. Would it be possible to add an option to disable user input to the edit text?

agraham · Apr 10, 2013

The InputDialog? Why would you want to do that

Custom dialog black background

Hello,

Very nice library. Thank you.

is there a way to change the black background in the custom dialog?

I couldn't find the differences between customdialog and customdialog2.

Is there any?

Thank you

Erel · Apr 23, 2013

Have you tried to set the panel's background color?

events do not fire immediately

Hi Agraham,

I run your dialogs demo on an android 4.0.4 phone, when I open a customdialog2, and click on the button, its event is fired immediately, but when I click on lv, its event will be fired after I close the dialog.
What's the problem?

Thanks for your help!

Erel · Apr 24, 2013

Handling events while a modal dialog is visible is problematic. I recommend you to use a non-modal dialog in this case.

Any idea ?

ret = cd.Show("B4A Custom Dialog", "Yes", "No", "Maybe", Bmp)

How to know which button was pressed? :sign0104:

agraham · May 24, 2013

From the help for Show

Returns one of the DialogResponse values.

Type "DialogResponse." in the IDE and Intellisense will show you the possible values.

EditText views in a CustomDialog don't wrap.

I have a CustomDialog with two EditText views. The user can fill in either, both or none. One of the views is for a text description or some other comments - not length restricted. I have set SingleLine = False and Wrap = True. I have the entire EditText view visible in the Panel but it doesn't wrap to a second line. Instead the top line just scrolls off the left side of the view.

Erel · Jul 4, 2013

I did a small test and it works fine:

It might be easier to work with a non-modal dialog.

Uitenhage · Jul 4, 2013

Thanks for the quick response. I really would prefer modal. Could you post code? That would help me immensely.

Thanks again.

Uitenhage · Jul 4, 2013

Erel, never mind.

I got it to work by commenting a line of code where I set the view up:

B4X:

txtComment.Hint = "Details, units, etc." 
txtComment.SingleLine = False
txtComment.Wrap = True
txtComment.Gravity = Gravity.TOP
'txtComment.InputType = txtComment.INPUT_TYPE_TEXT
txtComment.Text = "InitialText"   'DB.GetProductComment(b.Tag)
lblCount.Text = "Count" 
lblComment.Text = "Comment"

Does this make sense?

Thanks.

It's a known problem with EditText (if you move your InputType line above SingleLine = False, that should work). I solved that in my Masked EditText library.

Uitenhage · Jul 4, 2013

Thanks! I have posted questions in various .Net forums (including M$) over the years and have rarely (if ever) seen the responsiveness of B4A users!
