hi,

trying my luck again...


i've created this following general purpose function to be used in my B4A project
it works very nice but i have a few (non critical issues)

1.
the title - how can i lock the title so it will not be scrolled when the user scrolls the message content?
i want the title to be fixed as the bottom bar with the buttons

2.
how can i change the width of the buttons so i can use extra text if needed?

3.
is there a way to change the background color other than the theme?
for example red background and yellow text

4. can i change the background color of the bottom bar - the buttons bar?

i will appreciate any input
and of course i will be dancing on the table (you should mot even imagine this horror sight) if anyone will be kind and modify the code to support what i dream about...

thanks

B4X:
Public Sub zgShowDialog (Title As String, TitlebackColor As Int, TitleTextColor As Int, _
                        Msg As String, msgAlign As String, FontSize As Int, fontColor As Int, _

    Dim sf As Object = prefdialog.ShowDialog(Data, btnYES, btnNO)

        Sleep(0)
        prefdialog.CustomListView1.sv.Height = prefdialog.CustomListView1.sv.ScrollViewInnerPanel.Height + 10dip

    Else
        bRet = False
    End If
    
    
    Return bRet
    
End Sub
 
Solution
B4X:
b4xview2.SetTextAlignment("TOP", Dialog.Message.Alignment)

Let the function to allow for horizontal and vertical alignment.
YES!! YES!!
that works like charm
so now we have a full working solution
given - it the text is too long for the window size in height it will be cut, but that is OK as long as the text in the message is normal in length it is fine
i think we can leave this as is
i can't even think of keeping this and bein a pest - you really saved me here

to sunnarize:
a full flexible and controlled prefdialog mechanism with scrolling text - check!
to note: keep the text within a "normal" length or set the dialog height to a larger value

Dear aeric - i can't say how much i appreciate your help and value your work...

It seems you are making a duplicate post.
https://www.b4x.com/android/forum/threads/prefdialog-need-an-expert-eye-to-look-help.157368/

I think for 2 to 4, they may be not difficult. There are already answers on the forum. Try search with B4XPreferencesDialog keyword and your requirements.
I am not sure about #1.
well - almost
the first one got lost and ignored so it was declared "old" and i got a message to open a new one

as per 2 - 4 : i did search - couldn't find the exact answers i needed so i've asked here hoping...
as per 1: - this one is a tricky one (for me) but i do need to resolve it...

thanks for your attention

hi
found one issue with scrolling

take this message for example

Msg = "This is a demo message to show flexibility" & CRLF & "each element is fully controllable" & CRLF & "including scrolling the text"

and use the function with it
keep font size to 18
it shows all text perfectly

no double the message like

Msg = Msg & CRLF & Msg

and send it now
i mean to use the message window for a longer text
now the scroll is actually missing almost the entire "second" part

is there a way to fix the scrolled area so it will contain the entire text as long as it gets?

thanks

By the way, I can also replace the code for the message text:

B4X:
'    For i = 0 To PrefDialog1.PrefItems.Size - 1
'        Dim pi As B4XPrefItem = PrefDialog1.PrefItems.Get(i)
'        If pi.ItemType = PrefDialog1.TYPE_MULTILINETEXT Then
'            Log(i)
'            Dim ft As B4XFloatTextField = PrefDialog1.CustomListView1.GetPanel(i).GetView(0).Tag
'            ft.TextField.SetTextAlignment("CENTER", msgAlign)
'            Dim xfont As B4XFont = xui.CreateFont(Typeface.DEFAULT_BOLD, FontSize)
'            ft.textfield.Font = xfont
'            ft.TextField.TextColor = FontColor
'            ft.TextField.Enabled = False
'        End If
'    Next
    Dim MessageItem As B4XView = PrefDialog1.CustomListView1.GetPanel(0)
    MessageItem.Color = xui.Color_Red
    Dim MessageText As B4XView = MessageItem.GetView(0).Tag.As(B4XFloatTextField).TextField
    MessageText.TextColor = FontColor
    MessageText.SetTextAlignment("CENTER", msgAlign)
    MessageText.Font = xui.CreateFont(Typeface.DEFAULT_BOLD, FontSize)
    MessageText.Enabled = False

By the way, I can also replace the code for the message text:

B4X:
'    For i = 0 To PrefDialog1.PrefItems.Size - 1
'        Dim pi As B4XPrefItem = PrefDialog1.PrefItems.Get(i)
'        If pi.ItemType = PrefDialog1.TYPE_MULTILINETEXT Then
'            Log(i)
'            Dim ft As B4XFloatTextField = PrefDialog1.CustomListView1.GetPanel(i).GetView(0).Tag
'            ft.TextField.SetTextAlignment("CENTER", msgAlign)
'            Dim xfont As B4XFont = xui.CreateFont(Typeface.DEFAULT_BOLD, FontSize)
'            ft.textfield.Font = xfont
'            ft.TextField.TextColor = FontColor
'            ft.TextField.Enabled = False
'        End If
'    Next
    Dim MessageItem As B4XView = PrefDialog1.CustomListView1.GetPanel(0)
    MessageItem.Color = xui.Color_Red
    Dim MessageText As B4XView = MessageItem.GetView(0).Tag.As(B4XFloatTextField).TextField
    MessageText.TextColor = FontColor
    MessageText.SetTextAlignment("CENTER", msgAlign)
    MessageText.Font = xui.CreateFont(Typeface.DEFAULT_BOLD, FontSize)
    MessageText.Enabled = False
this code change blocked the scroll and actually displayed only part of the text
with no scroll option

I think you need to try with different values of DialogHeight.

B4X:
PrefDialog1.Initialize(Root, Title, 300dip, DialogHeight)
yes, if i set the height to a larger value it works but then it is not as general as i wanted
i wanted to have a fixed container and scrollable text
one other reason is when a user set the phone font size or screen size larger it all changes
so the best solution is to allow scrolling, this way it will show all text at any size
do you think the original beautiful function you created from my lame one - can it be set to scroll the entire text?

I think you need to try with different values of DialogHeight.

B4X:
PrefDialog1.Initialize(Root, Title, 300dip, DialogHeight)
changing DialogHeight value from 200 to 400 for example doesn't have any impact and does not chage the message window height at all

changing the 200 to 200dip for example will enlarge the height but the title disapears

looks like the best solution is to cancel scroll and keep the text "normal" size
how can i calculate the dialogHeight to suit the text and keep the title?

I have been trying to use Custom Dialog. After hours of trial and error, here is what I got.
