elfparser-ng's Issues

Menu option names

I suggest the following changes to menu options:

• Rename Find Table Section to Find Section under Edit.
• Rename Find Table Symbols to Find Symbol under Edit.
• Rename Find Table Programs to Find Segment under Edit.
• Move Edit -> Hex -> Goto... back to Edit -> Goto....

Parts of text missing in tables

Because the text in centered, I can't read the full content of the cell (unless I have a really huge monitor, which is not the case):

Crash on Ubuntu 22.04

If you open a file and resize the left column all the way right to the end, you get a crash and a Floating point exception (code dumped) message:

Can't see headers in hexadecimal viewer

System: Ubuntu 22.04

Is this really needed? Maybe we can just remove it.

Content not shown in hexadecimal viewer

I think there's a problem with the font color here. The content is there, but I couldn't see it unless I selected it:

Offset address update

When you click a byte in the hex view, the Offset address at the bottom does not update.

Needed libraries on Ubuntu 22.04

I had to install both FUSE and qtbase5-dev before running the AppImage on Linux (Ubuntu 22.04 64-bits). Fixed with:

sudo apt install fuse qtbase5-dev

Is this expected?

After installing both and trying to execute the AppImage binary, it says libicudata.so.71 is missing. It also complains about libicui18n.so.71, and libicuuc.so.71. Here's how I fixed it:

ln -s /usr/lib/x86_64-linux-gnu/libicudata.so.70.1 /usr/lib/x86_64-linux-gnu/libicudata.so.71
ln -s /usr/lib/x86_64-linux-gnu/libicui18n.so.70.1 /usr/lib/x86_64-linux-gnu/libicui18n.so.71
ln -s /usr/lib/x86_64-linux-gnu/libicuuc.so.70.1 /usr/lib/x86_64-linux-gnu/libicuuc.so.71

Then it runs.
