Schematic Editor: View All -> wrong scaling

[3813127458]

The schematic editor performs wrong graphics scaling of the schematic diagram at "View All". Probably the long Nutmeg script is the root cause for this issue(?)

I've conducted a quick research: it seems like the cause of described behavior is this line. It calculates the width of a rectangle able to hold the text of the script, but selected boundingRect method doesn't treat newlines as line breaks (see QT doc there, so the script is treated as a one-liner. Possible solution is to use one of the overloaded boundingRect methods which treat newlines properly.

I'll try to make a fix using a proper method.

Another way this issue is caused is when a wire or any "Painting" like a line, ellipse, circle..etc is so short or small to be unviewable.

A "phantom" net caused by cut-paste or moving multiple items can also be a pain to locate and delete

I've had to use a text editor to find and delete the item...

@tomhajjar could you please provide an example file or a video? I'm not sure I understand clearly how to reproduce the described issue.

Make a wire or any "Painting" like a line, ellipse, circle..etc that is so short or small to be unviewable and place it out of the desired viewable area.

Attached is a schematic with a line and ellipse with a dimension of "0". If these end up "off screen" they both screw up "Zoom All" AND they cannot be selected for deletion. Only a text editor will find and delete them.

The "phantom" net is harder to reproduce since I don't know what causes it other than it randomly occurs during a cut-paste or moving of multiple items. The net name is visible but detached from the actual net itself. The net name can be so far away from the "schematic" it becomes invisible when zoom all is used. If you can find it you can click on it and delete it. I usually end up deleting the net and hope it disappears but unfortunately it doesn't always work. I end up using a text editor to find it in the schematic and delete it.
