When you open IPythonQt you see a menubar and a (still undeletable) input cell in which you can write ipython/python code.
You can execute the code written by pressing Ctrl+Return (shift doesn't work, I dunno why), or just go to the menu 'evaluate'.
You can call a context menu inside the cell which besides the standard buttons it has a new one to delete the cell.
If you right-click somewhere else in the notebook, a tiny context menu should appear to append a new input cell or to delete the last focused cell. A focused cell is the last you clicked, not the last you hover.
If you connect another frontend to the same kernel, another widget will come out with the info of the variables that changed and the user.
Some shortcuts has been created for the keyboard lover:
Ctrl+UpArrow goes to the previous cell
Ctrl+DownArrow goes to the next cell
Ctrl+Shift+UpArrow goes to the previous executable cell
Ctrl+Shift+DownArrow goes tot he next executable cell
Ctrl+Shift+N appends a new cell
Ctrl+Shift+Delete removes the current cell
Ctrl+Return Executes the current cell if it's executable
What you cannot do (yet):
The code still doesn't capture pyout, so code like:
won't produce any output.
Calls to raw_input, %, !, system commands, tab completion, function tooltips, gdb and help.
Work right in progress:
Stdin support, since I have to have it finished for the mid-term evaluation, it's the main concern. The popup widget it's finished but there's still the raw_input function in the kernel that needs to be implemented correctly.
There's a new output cell if the same input cell is modified.
There's a discussion in the mailing list about if the different outputs from the same input should be on different cells (packable) or in the same cell.
The resizing of the cell when the block(line without '/n') is larger than the size of the window. For what I've seen this is not trivial.
