Add a new option for replacing the edit data dialog by an edit data dock
widget which is added to the main window and remains visible. This might
be interesting for people who otherwise would have to open the edit
dialog many times by doing tons of double clicks.
Use a common format for all include guards, make sure each header file
has one and make sure it's named after the file name.
And as a random extra in this commit: Make sure the gen_version.h file
generated by cmake ends with a line break.
Closes#59.
Read and write the settings only from the preferences dialog.
Remove all the copies of some settings which were stored in nearly every
dialog class individually.
Simplify the settings dialog code by removing all those not really
needed slots.
By default, use the overwrite mode in the hex edit widget. This way text
and hex editor start in the same mode, making it less confusing to press
the INS key to change the mode.
When editing the data using the hex editor also update the text editor.
Allow the user to change between the text editor and the hex editor.
Allow the user to change between insert and overwrite mode in both
editors.
This makes it possible to enter any binary data into an empty cell.
Store the data of a DB cell in a QByteArray, i.e. a binary data type,
instead of putting it in a QString, thus converting it to a UTF8 string.
Rewrite the reading and writing of DB cells to correctly handle binary
data containing 0x00 bytes.
Change the edit dialog to actually do all the data checks etc. on a
currently invisible QHexEdit widget instead of a QTextEdit.
All these changes combined make it possible to actually store binary
data without it being corrupted. You can for example import pictures
now, export them and actually open the exported file. So this is an
improvement.
Create a Qt Designer form file for the edit dialog.
Clean up the edit dialog code removing some not working and not used
functionality e.g. for blob editing.
