If you would use the rectangle selection tool over a number of entities (some selected, some not) the tool cannot know if it is supposed to add the entities to the selection or remove them from the selection. It requires more user input to decide that.
Sorry Andrew but I have to disagree. Is this the case for QCad I have to accept that but it is a normal function in Windows OS's and many Programs what consequently brings me to the point that it can't be a general logical reason!
Also - it is for QCad logical to expand a single selection with the Shift key and a mouse click and it is for QCad absolute logical to de-select an element if it is already selected.
But with a selection rectangle and a shift key it can't work for a logical reason .... is that not based on the same Feedback like the single (de)selection?
It is the daily procedure to work in Windows with shift or Ctrl (Strg) to make selection with mouse or boxes and it is not a problem for windows to recognized "selected" or not "selected" to reverse the selection with a Box over function in one step. And it doesn't need more input - you can do it with the mouse + a shift or a Ctrl Key. Just test it on a Windows Desktop - select every second Folder - and use a Selection Box with pressed Ctrl Key ....
Yes, you are right that we haven't spoken about the Ctrl Key but this one is already reserved in QCad for the Pan Function, right?
