Provides various kinds of good-to-have-at-hand tables for charsets, colors
10
Brief application overview:
12
The dialog is wrapped around a QTableView. QAbstractTableModels
13
are dynamically inserted at runtime. Each model is packed in a ModelFactory
14
wich can hold multiple models in multiple categories. All ModelFactories
15
are then handed out to the the controler of the dialog for further processing.
18
The dialog comes equipped to handle the Eric4 special functionality
19
of inserting the contents of a selected cell directly into at the current position
20
of the current editor, but may aswell be used as standalone dialog.
23
Note that chars may or may not get displayed properly. Also some
24
ranges in some encodings are left out for performance reasons.

# in no particular order

# - anyone for more tables?
51
# - currently clipboard and drag offers only 'text/plain' format
52
# - some visual feedback would be nice to indicate an item was copied/inserted
54
# - tooltips for truncated items are not 100% accurate. Pretty hard to find out
55
# when exactly Qt truncates strings in combos.
56
# - toltip for edit filed in combobox flaps out a tad to fast. Higher delay
59
# - maybe an option to make the dialog stay topmost?
60
# - maybe a gridlines on/off option?
