[Gambas-user] How do I pass a user parameter from a dialog form?

[Martin M. <mmc...@fr...>]

Hello,

 

I have created a dialog form. As created by Gambas, it has an OK and Cancel
button. I want to return three properties or an array from the form. One
each for the three textboxes on the form.

I added a textbox to the form to test it. Call it Textbox1. Used the code
below to add a property called "Login" to the Dialog:

 

Property Login As String

Private strLogin AS String

 

Private Function Login_Read()

                Return txtTextbox1.Text

Return

 

Private Sub Login_Write(Value as String) as String

                strLogin = Value

End

 

I call the Dialog from the main form by frmDialog.ShowModal. When I load the
frmDialog, enter the text in the textbox and click OK. The Dialog closes but
no value is returned to the main form.

If I explicitly set Login_Read to Return "XYZ" it works  properly. It
returns "XYZ" to the main form. If I try to get the contents of
Textbox1.Text it returns an empty string. There has got to be a way of
returning the value of a textbox as a property of a dialog form.  I'd rather
not use public variables on the main form as there are too many variables
already.

 

Would you guys please point me in the right direction.

 

Thanks,

Marty

Hi Marty,
you would use a new class file were store your variables. In this case 
the class is a bridge from your dialog to main form

Re: [Gambas-user] How do I pass a user parameter from a dialog form?

[Roki <n.r...@gm...>]

try this:
1) in main form

Property Login As String

Private strLogin AS String

Private Function Login_Read()

       Return strLogin

End

Private Sub Login_Write(Value as String) as String

        strLogin = Value

End

Private sub Button1_Click()
	dim f as new frmDialog <-- Your name of dialog form
	if f.ShowModal() Then return
	TextBox1.Text = strLogin

End

2) On DialogForm
    when you click on OK button
    Private Sub btnOK_Click()
    FMain.Login = TextBox1.Text < ---I guess  this is the name of TextBox on your dialog form
    End

And 3) I'm sorry for my bad English, and
I  guess this  will help!

Re: [Gambas-user] How do I pass a user parameter from a dialog form?

[Fabien B. <gam...@gm...>]

the common way is :


In the form :

Static Public Param1 as string
Static Public Param2 as String
Static Public Param3 as string


Public Function Run(hParam1 as string, hParam2 as string, hParam3 as
string) as boolean

dim hForm as FDialog

Return Not Me.ShowDialog()

end

Public Sub Form_Open1
  TextBox1.Text = Param1
  TextBox2.Text = Param2
  TextBox3.Text = Param3

end

Public Sub btnValidate_Click()
  Param1 =TextBox1.Text
  Param2 = TextBox2.Text
  Param3 = TextBox3.Text
  me.Close(True)
End

Public sub btnCancel_Click()

  Me.Close

End


Calling the form :


FDialog.Param1 = "myparam1"
FDialog.Param2 = "MyParam2"
FDialog.Param3 = "MyParam3"

If Not Fdialog.Run() then

Print FDialog.Param1 ,FDialog.Param2 ,FDialog.Param3

endif

This is a standard task and therefore a "template solution" evolved in the
Gambas sources. Attached is a project which shows how to do it cleanly, no
public variables and no auxiliary classes needed.

If you have a problem with the project and comments being German, I will
translate it for you...

Thanks for that example. Never realised there would be this way to do 
it. It does indeed save a lot of trouble with values from dialogs. On 
the other hand, it means changing the form calls I'm used to from a 
simple "formxyz.ShowModal" to "DIM hForm As New formxyz" "aCollection = 
hForm(...)".

Let me ask two things I stumbled over when studying the code:

Where would I find this "call" thing in the documentation? F2 doesn't 
react to event calls, and I cannot find it under the event descriptions 
(like Event Management etc.).

Why is a SUB used with a Return value? Wouldn't it be more up to 
standards to use a FUNCTION instead? (As far as I understand, a SUB is a 
function without a return value, one that would be of type "void" under C.)

Function sub and procedure are the same . It's just a use

_call is a special method that allows you to use an object like a function.
It is documented in the "Special methods" section[0].

However, it is not mandatory here. In Gambas sources you mostly see a
function named Run() instead. I just like the _call() syntax better.

Definitely! Usually I do that, but sometimes signatures change when I
develop the code further. I must have overseen that spot. Anyway, in
Gambas Sub, Procedure and Function are mutually interchangeable.

Hi Tobias,

I found the solution...

Make a collection array within the dialog or within the _call function, 
then add the items and

Return aMyCollection

will do the rest.

Need another cup of coffee :)

Hi Tobias,

After some time, I had the chance to look at this thing again:

My question is, when I have more than a few parameters to state, how can 
I achieve that?

Now it is

Return ["name": txtName.Text, "password": txtPassword.Text]

but when I have 200 or more things to pass? Or is the collection thing 
too slowly for such a number of items?

Re: [Gambas-user] How do I pass a user parameter from a dialog form?

[Fabien B. <gam...@gm...>]

you can use collection too I use collections to manage hundreds images
in gb.map cache for example. I don't see other simple way in your case
