EA b1419: Zoom Controls and View are not synchronized.
« on: May 15, 2018, 06:46:54 pm »
There is at least two controls which let change the (diagram) zoom: the slider at bottom right of the screen and the slider in the Pan & Zoom View. They are not synchronized (see also http://www.sparxsystems.com/forums/smf/index.php/topic,31160.msg225636.html#msg225636). Also they do not change when a diagram will be zoomed via Ctrl + Mouse Wheel.

The view element that shows current zoom in the status line changes only when a diagram will be zoomed via Ctrl + Mouse Wheel, but does not change on zoom via sliders.

The zoom on the status bar is a personal zoom level that applies to all diagrams.

The zoom on the Pan & Zoom and Ctrl+mouse wheel allow you to temporarily zoom on the current diagram.

The zoom slider on the right of the status bar is a user preference that is additional to the other zoom controls. If you have a small monitor, you may want all your diagrams to be zoomed out - move the slider to the left. If you have poor eyesight, you may want all your diagrams to be zoomed in - move the slider to the right. This does not affect the way other people see the diagrams, it just redefines (for yourself only) what 100% zoom looks like.

Thank you for clarification. :) I should read user manual.

Has the option "Preference / Diagram / Zoom to best scale" no effect?


The zoom on the Pan & Zoom and Ctrl+mouse wheel allow you to temporarily zoom on the current diagram.
If these two User Controls have the same effect, I suppose, they both should affect the zoom percent view (on the left of the status bar) equally. The Pan&Zoom slider doesn't affect it.

Looks like the status bar isn't redrawn after the zoom isn't changed there. As soon as the mouse is moved off the slider the status bar gets updated.

Ok, I found the problem. The option "Show Tips in Status Bar" is deactivated (with me). Therefore the mouse cursor movement does not affect the status bar.

It means, change of zoom (via either Pan&Zoom slider or change "Persistent Zoom" setting) does actually not update the Zoom View on the status bar. Only if some side effect (e.g., status bar updating with the activated option "Show Tips in Status Bar") forces this update, it hides the bug.
