You can put a Panel on the form and then handle MouseMove event to change its Top position.

There are many examples in the forum that will help you get started.
Here is a very basic tutorial: http://www.b4x.com/forum/tutorials/859-my-first-application.html

I need a small tutorial about scroolling in form.
I have a bunch of image buttons or buttons.
For example the form as space for only 10 Image Buttons and i want to use 15 image buttons , so i need to scroll along the form, like we do in android. it is possible on device?

Best Regards

hi,
something like this(?):

Sub Globals
'Declare the global variables here.
dim buttons(0)
dim startx,starty
End Sub

Sub App_Start
Form1.Show
End Sub


Sub Form1_MouseDown (x,y)
startx=x
starty=y
End Sub

Sub Form1_MouseUp (x,y)
buttons() = GetControls("Form1")
For i = 0 To ArrayLen(buttons())-1
'Control(buttons(i)).left=x
Control(buttons(i)).top=Control(buttons(i)).top+y-starty
next
End Sub

for smooth scrolling you have insert some steps.

I haven't tried any of this, but won't there be a problem that the "mouse" touch has to be between the buttons so that the button itself does not get the mouse action. This means big gaps between the buttons, which will make use of the screen "real estate" even worse.

But then I don't have an Android to compare either...

You can use Door Library.


Sub App_Start
Form1.Show
DoorObject.New1(False)
DoorObject.FromControl("Form1")
DoorObject.SetProperty("AutoScroll", True) "AutoScroll"
End Sub

You can use Door Library.

But gatoazul1973 appears to be an unregistered user so I suppose will not be able to get additional libraries.

I'm afraid that you can't do it in B4PPC, exactly like in Android.
I would suggest you to put all the Controls onto a Panel, add a ScrollBar from the FormLib library which will aloow you to scroll the Panel on the form.

Best regards.
