Hi everyone,

I design a small app under Ubuntu.

I am currently using the Layout Designer to design the layout of my app.

I want to display three images (successfully imported in my .iml) which are 32x32 pixels each, vertically, and with no margin between them, like this:

 ----
| 1  |
|    |
 ----
| 2  |
|    |
 ----
| 3  |
|    |
 ----

On the layout designer, I create User Classes with ImgCtrl class and I make the borders touch themselves. I checked in the text content of the layout file, everything is alright, I have 32 pixels between each position.

But when launching the real app, I am disapointed to see they do not touch themselves anymore.

I then tried to change the DPI of my screen, and tada ! I can see that the relative position (in pixels) between the ImgCtrls is not the same.

I believe this is because we are dependent on the dpi when positioning images.

How can I solve my problem ?

Here is the illustration at 96 dpi (original):

index.php?t=getfile&id=2051&private=0

And at 72 dpi (images correctly touch themselves)

index.php?t=getfile&id=2052&private=0

Thanks,
Lionel
