Description Robert Hairgrove 2018-01-24 09:59:42 UTC

First of all, it is very nice to have the grid and the alignment features for widgets. However, there seems to be no easy way to make similar widgets all the same size, so I do this manually.

But after I save the file and reopen it, Umbrello has changed the widths of some widgets seemingly at random. This is very frustrating, to say the least!

Also, when resizing a widget, I have to grab the lower left corner, although most often I only need to drag one of the edges. Working on a laptop, it is difficult to resize just one edge at a time. And it would be nice if the resizing function would also obey the grid.

...should be "lower RIGHT corner", of course.

In the diagram property page there is a checkbox "snap component size" exactly for this purpose.

I adding several widgets with this checkbox avtivated, saved as xmi file file, reload it without any issue. Can you confirm ?

Thanks for the tip about sizing ... strange that this option is missing from the main menu, that it is necessary to open the dialog to find it.

I tried making a very simple case with a package, four classes and four links to the package. I saved it, opened it again and saved the file without making any changes to a new file name.

Although I couldn't see any difference by just looking at the screen, I ran the GNU `diff` command on them. There were a few differences in the following lines:

    (file 1): <startpoint starty="-475" startx="-1552"/>
    (file 2): <startpoint starty="-475" startx="-1550"/>

and 

    (file 1): <diagram canvaswidth="375" [...]>
    (file 2): <diagram canvaswidth="350" [...]>

In the Umbrello configuration, I noticed the option for "Auto Layout", which was selected. Could this have anything to do with unwanted changes?

I had a much more complicated layout which had difficulty with resizing. Maybe I can duplicate it in a test case.

Comment 4 Robert Hairgrove 2018-01-28 22:57:45 UTC

I'm thinking there must be rounding errors somewhere in the code. It's strange that Umbrello would change anything at all in the XMI file for a diagram that was not changed by the user (except for things like the timestamp, etc.)

You did that on the same machine and the same monitor ? stable umbrello versions currently saves files with coordinates/widget sizes based on the used monitor dpi (see bug 90103)

no, these settings only enables the search for dot excutable by default. Auto layouts are applied only manual.
