asammdf-gui copy may cause only partial copy

[mm-mm-bb]

asammdf-gui version

development https://github.com/danielhrisca/asammdf/commit/872af032174317c8107ac4fa3bff4b766024e612 (broken) release 7.5.0.dev2 (broken)

Description

• open some can mf4 can trace (in my case from canEdge1) with decent amount of data (>100.000 messages)
• enter "Can bus trace" view
• select a big chunk of data (all), ctrl+c
• in a text editor ctrl+v

both editors and asammdf will hang, after hanging the copied text has good changes to be only a cell instead of all the selection, sometimes panda/clipbard error on the console, sometimes dont, not sure if related (cant reproduce)

Workaround

wait for asammdf to complete the "copy" before pasting; try switch tab or click a single element. asammdf will hang until the "copy" is run, but after it will get unstuck, the ctrl + v will work as expected and paste all the selected data. Probably quick fix is to add a little load animation

@mm-mm-bb please try the development branch code

tested with a 2mln and a 600k record file, now only the asammdf hangs (not responding). Much better, but still a little "hey, this may take some time" message and/or a loadbar would be nice
