Reuse the "Cell value" dialog #45
Description
This is a spin off of #41.
As of now, each double click on a cell (when browsing through the table contents, i.e. NOT the results of a SQL statement) produces a new "Cell value" dialog instance. If I want to quickly inspect several cells, I end up with many open dialogs (which are then cumbersome to close).
It would be nice if the dialog could be reused for displaying of cell values. I.e. if the dialog is already open, it gets reused for displaying a cell value on double click (without opening a new dialog instance).
But sometimes it's desireable to see two values at the same time, i.e. to have multiple instances of the dialog. This could be achieved by having a check box (or a "pin") in the dialog. If it's activated, the dialog gets reused when a cell is double clicked. If it's not activated, a new dialog is opened.
In the results of a SQL it's possible to display the same dialog which ist always reused. Hence the problem is not present there.
Thank you for the great program!
