Arrange All [message #219530]

Hi,

I wrote my own LayoutProvider for the "ArrangeAll" command. The provider is called when I select the
menu "arrange all". So far so good.
I can tune the layout by some properties in preferences. All works fine.

Now my problem:
After I change a property in preferences I select "arrange all" in the menu. The layout changed.
Than I select again "arrange all" and the nodes move again a little bit. They move one grid spacing.
The layout after the second call is the correct layout. I compared the Bounds values from the first
and the second "arrange all" command. All values in the second call are identical to the first call
but the displayed layout in the diagram are different.

Does any one experienced this problem before? How to solve it?

BR, Martin

Hi,

I still looking for the reason of the below described behavior. I found out the problem exist only
when the diagram property "Snap to Grid" is selected. But I dont understand the behavior because my
own LayoutProvider place all nodes exactly at the grid.
Still no glue what is the reason for my problem :(.

As a workaround I may disable the "Snap to Grid" property. How can I do this?

BR, Martin
