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.

I did that, but the library is still not on the list, I'm not getting why some of the libraries register fine and some don't (?)
Now getting to the App:
It compiles fine and runs but the only thing I can get from it is a student list. Nothing else. I see there are some procedures defined (i.e. FillStudentsTable, ExportToJSON etc.) but it seems like there is no access to it. I would suggest when posting an example like this to put some description as what the App supposed to do, otherwise it is confusing for newbies like me.

Where did you install B4A ?
Is it in C:\Program Files\Anywhere Software\Basic4android ?

In your previous post you say that you copied the files to
C:\Program Files\Anywhere Software\Basic4android\Libraries\Dialogs2.2

You must copy Dialogs.jar and Dialogs.xml to
C:\Program Files\Anywhere Software\Basic4android\Libraries
with their orignal names.

Best regards.

OK, I thought if I could store it in subfolder (it would be more organized this way). Also I did not expect to close and reopen application for see the changes. After copying to the main LIB folder I can see it now, but

when I compile an example I still get error:

Compiling code. Error
Error parsing program.
Error description: Unknown type: colordialog
Are you missing a library reference?
Occurred on line: 71
Dim cd As ColorDialog

Thank you - Arthur

klaus · Jun 1, 2011

Did you check the Dialogs library in the Lib tab ?

Best regards.

aklisiewicz · Jun 1, 2011

that was it, I checked it and it works.
This library looks great, I really love it!
Thank you for your time.

PS>
one other problem I have (but it is not related to your App only) is the timeout message I get while compiling some Apps (including yours), and without pushing it further it sits there with this message on the screen. do you know if there is any way to resolve this ?

Hi Andrew,

thank you for supplying the dialogs library. When using the code below and entering a number like 12.3 the number dialog returns 123 thus not returning the decimal separator. Do you have any idea what goes wrong?

With regards

Christian

B4X:

'using dialogs library version 2.2
Sub Globals
   Dim lblInput As Label
   Dim nd As NumberDialog
End Sub

Sub Activity_Create(FirstTime As Boolean)
   lblInput.Initialize("lblInput")
   lblInput.Color=Colors.White
   lblInput.TextColor=Colors.Black
   lblInput.TextSize=30
   Activity.AddView(lblInput,10,10,60,30)
   nd.Digits=4
   nd.Decimal=1
   nd.ShowSign=True
End Sub

Sub lblInput_Click
   nd.Show ("","OK","","",Null)
   lblInput.Text=nd.Number
End Sub

You could try to change the Timeout value.
Sometimes, I remove an existing Emulator and create a new one.

Best regards.

alfcen · Jun 1, 2011

Please write:

lblInput.Text = nd.Number / 10

or:

lblInput.Text = nd.Number / Power(10,nd.Decimal)

for multiple use.

Christian · Jun 2, 2011

Hi Alfcen, thank you very much for your helpfull advice, Christian

agraham · Jun 5, 2011

In version 2.3 now posted CustomDialog and CustomDialog2 now internally remove the Panel added to them byAddView. this allows a Panel declared as a Global to be built once and reused rather than needing to create a new Panel every time.

TimeDialog showing hour+1

Hi

Thank you for the great library. I'm using the TimeDialog with 24 hours format.

The TimeDialog shows always one hour later than what I set in xx.Hour, e.g.
this code snippet

Dim td As TimeDialog
Dim txt as String

txt = "18:35"

Td.Hour = DateTime.GetHour(DateTime.TimeParse(txt))
Td.Minute = DateTime.GetMinute(DateTime.TimeParse(txt))
Td.Is24Hours = True

ret = Td.Show("Enter time", "Time", "OK", "Cancel", "", Null)

shows "19:35" within the dialog.

Do I have to subtract 1 from the hour value before passing it to the TimeDialog?

Thank you in advance for your help!

Ivan

agraham · Jun 6, 2011

I assume, although you don't show it, that you must have changed DateTime.TimeFormat as with the default setting your code fragment throws an "Unparseable date" exception. Having inserted that in the code I do not see the effect you describe. The expected values of 18 and 35 are shown in the dialog.

B4X:

   Dim td As TimeDialog
   Dim txt As String
   txt = "18:35"
   DateTime.TimeFormat = "HH:mm"
   Td.Hour = DateTime.GetHour(DateTime.TimeParse(txt))
   Td.Minute = DateTime.GetMinute(DateTime.TimeParse(txt))
   Td.Is24Hours = True
   ret = Td.Show("Enter time", "Time", "OK", "Cancel", "", Null)

IvanR · Jun 6, 2011

Yes, you are right. I forgot to mention that I have changed the format as follows

DateTime.TimeFormat = "HH:mm"

vangogh · Jun 8, 2011

wish... numeric keypad

the "getnumber" is a bit "strange". you compose a number using +/- on a predefined lenght...

what about a nice numeric keypad?

thanx

I have the following code in my app:

B4X:

Dim ret, ret2 As Int

ret = -2
 
Do While ret = -2
    fd.ChosenName = ""
    ret = fd.Show("Choose a deal to replay:", "Open", "Cancel", "Delete", Null) 
    If fd.ChosenName = "" Then Return
 
    If File.Exists(File.DirDefaultExternal, fd.ChosenName) = False Then
        Msgbox(fd.ChosenName & " does not exist.", "")
        ret = -2 ' repeat loop
 
    Else If ret = -2 Then
        ret2 = Msgbox2("Confirm: delete?", fd.ChosenName, "Yes", "No", "", Null)
        If ret2 = -1 Then
            xx = File.Delete(File.DirDefaultExternal, fd.ChosenName)
            If xx = False Then Msgbox(fd.ChosenName & " was not deleted.","")
        End If
    End If
Loop

I thought that I had read somewhere that the three options in fd.Show returned -1, -2, -3, but instead, it is returning -1, -3, -2 such that Cancel= -3 and Delete= -2. Is there something in my code causing this?

Also, I would like to add an option to email a file, but it appears that fd.Show is limited to 3 options. Is there a better way to accomplish all of this?

agraham · Jun 17, 2011

Those response values are as expected.

kickaha · Jun 17, 2011

Your code will also be easier to follow if you use DialogResponse.CANCEL etc instead of numbers.

If you check my code, you'll see that most of what I'm operating on is when the user has selected DELETE, which I substituted for NEGATIVE, so using DialogResponse.NEGATIVE (since there is obviously no .DELETE) wouldn't help the readability, I don't think.

The Dialogs library is a very important library. Please keep this thread informative and related to the subject.

kkolle · Jul 4, 2011

Hi Andrew,

I´m using the TimeDialog!
When I´m using the keyboard to set the minutes to "00" I still get the initialized minutes.
I hope the attached screenshots could help!
