/*! QHexEdit is a hex editor widget written in C++ for the Qt (Qt4) framework.
|
|
It is a simple editor for binary data, just like QPlainTextEdit is for text
|
|
data. There are sip configuration files included, so it is easy to create
|
|
bindings for PyQt and you can use this widget also in python.
|
|
|
|
QHexEdit takes the data of a QByteArray (setData()) and shows it. You can use
|
|
the mouse or the keyboard to navigate inside the widget. If you hit the keys
|
|
(0..9, a..f) you will change the data. Changed data is highlighted and can be
|
|
accessed via data().
|
|
|
|
Normaly QHexEdit works in the overwrite Mode. You can set overwriteMode(false)
|
|
and insert data. In this case the size of data() increases. It is also possible
|
|
to delete bytes (del or backspace), here the size of data decreases.
|
|
|
|
You can select data with keyboard hits or mouse movements. The copy-key will
|
|
copy the selected data into the clipboard. The cut-key copies also but delets
|
|
it afterwards. In overwrite mode, the paste function overwrites the content of
|
|
the (does not change the length) data. In insert mode, clipboard data will be
|
|
inserted. The clipboard content is expected in ASCII Hex notation. Unknown
|
|
characters will be ignored.
|
|
|
|
QHexEdit comes with undo/redo functionality. All changes can be undone, by
|
|
pressing the undo-key (usually ctr-z). They can also be redone afterwards.
|
|
The undo/redo framework is cleared, when setData() sets up a new
|
|
content for the editor. You can search data inside the content with indexOf()
|
|
and lastIndexOf(). The replace() function is to change located subdata. This
|
|
'replaced' data can also be undone by the undo/redo framework.
|
|
|
|
This widget can only handle small amounts of data. The size has to be below 10
|
|
megabytes, otherwise the scroll sliders ard not shown and you can't scroll any
|
|
more.
