Can't change HMI element size

[Sandy]

Hi,

I've just upgraded to UniLogic 1.29.111, and I've noticed I can't change the size or position of HMI elements with the mouse or properties editor. I can move them with the cursor keys, but that's all. Also, the "Arrange HMI elements" buttons  stay grayed out when multiple HMI elements are selected.

Is this an issue with this version of UniLogic? Anything else it could be? It's a fairly large, complicated project that's just been updated from 1.18.60.

Are the elements or screen locked by any chance?

I see in the version changes that UniLogic 1.18 already contained the Improved HMI Editor. However, the Lock Elements feature was not working, an it was fixed in later versions, so maybe you've locked some elements or screen before upgrading UniLogic, and now the lock actually works.

The Element isn't locked - I tried locking it, and that prevented the cursor keys from moving it.

The screen isn't password protected (if that's what you mean), though there are other password protected elements in the project.

There is second lock on the screen level, if you look under screen properties there is check box "Lock Screen".  If it is set there is no lock watermark like it is, if element is locked. You simply can't drag elements around.

Click on an empty area of the screen, or if an element is selected press Escape once or twice so no element will be selected.

Now when you see the screen properties in the property grid, look for "Lock Screen". If it's checked then uncheck it,

That's it, thank you both.

I'm still surprised you can paste elements, and move them with the keyboard when the screen is locked. Is this the intended behaviour? If so, the help could be improved to explain that.

Yes, it is by design. Locking screen just there to prevent you from accidentally moving an element, and does not prevent paste or delete (it is not meant for preventing changes to the screen).

When you select an element and press the arrow keys, you usually want to move the element (using the keyboard is more for moving the element 1 or few pixels to a specific location, since it is more accurate / allows moving by only 1 pixel and only 1 direction).

 

The Lock of specific element was added later (in version 1.18) along with the improved HMI (speed, memory and features), which later allowed adding the Layers support (I think version 1.19)
