Description

The labeling settings window's width expands to the width of the monitor when a large expression is used as label. What I think happens is that the expression widget's text input tries to grow to display the expression string as much as it can. That's not a bad idea, but the end result is really bad for very long strings (which happens as soon as you add a few conditional statements in there). There should be a reasonable growth limit that prevents the window from filling the monitor's width.

See attached screenshot. Problem started in the late stage of QGIS 2.4 development, and currently affects master too.

Setting priority to high as it is very problematic on small monitors.

History

#1 Updated by Arnaud Morvan almost 10 years ago

Tested on master with Ubuntu 14.04, works good, not expanding.

#2 Updated by Mathieu Pellerin - nIRV almost 10 years ago

Arnaud, screenshot please? :)

The label must be a long expression string.

#3 Updated by Giovanni Manghi almost 10 years ago

  • Resolution set to fixed/implemented
  • Status changed from Open to Closed
  • File labels.png added

I tested also on Windows/master, it works as expected too.

Definitively not fixed. Steps to reproduce:
1. Create a project, add one vector layer (polygon, point, line, doesn't matter)
2. Open the Layer Properties window, and go in the label section
3. Activate the label checkbox and paste the following expression as label: CASE WHEN 1 = 1 THEN 'insert a label, make this expression long' ELSE 'insert a different label, not fixed' END
4. Close the Layer Properties window to apply the label
5. Re-open the Layer Properties window, see how its width as grown to unreasonable size. It can't be reduced in size either.

#5 Updated by Giovanni Manghi almost 10 years ago

  • Resolution deleted (fixed/implemented)

I tested again on latest qgis master (on Windows and Linux), made the expression very long, and on reopening the vector layer properties the dialog stays at an acceptable size. I will post a cast.

I'm at lost here :)

I've made a screencast of how the UI behaves over here, hope that can help.
