Hi,

I have a form with a blist object and some image buttons at the
botton (button.top = 225) of my form (Screensize : 320 x 240 )

I compiled with device + autoscale.

The blist object is ok, but the image buttons are not at the correct position.
They are to much up

Omnia : 800 x 480 , it should run on a 320 x 240 device too.

ScreenScaleX = 2
ScreenScaleY = 2

What can I do ?

Click to expand...

They are in a higher location because autoscale calculates for QVGA and VGA. You should use (Form.Height - 95)

If I understand correctly you are designing the layout on the desktop. In that case you should set the form size (Designer form - Tools - Screen Size) to 240 x 400.
AutoScale feature doesn't change the layout of the form. So if you design your form for a 240x320 screen then it will look identical on 480x640 screens as well. But on a 480x800 you will get some empty space at the bottom.

Ok this I understand. I want to develop a software which runs on all screen sizes
(320 x 240, 480 x 800 ...),
and my image buttons should be always at the same bottom line.

I can compile without autoscale and position the objects by my own.
So autoscale it´s much easier. Can´t I reposition the objects depending on
the (formsize * screenscale) = screensize and calculating a factor to reposition.
Did somebody do this yet ?

In my case I tested with a htc touch 3g 320x240 and an omnia 2 800x480

First I changed the screen size to 400 x 240
In my project I use only ImageButtons as menu.

I use the following code in my sub app_start :

Controls() = GetControls("")
For i = 0 To ArrayLen(Controls())-1
Select ControlType(Controls(i))
Case "ImageButton"
Control(Controls(i)).Top = form1.Height - Control(Controls(i)).height - 5
End Select
Next

I compile the my project with autoscale.
It works fine on both resolutions (phones).
