Widgets and Views

The last release of the Profiler featured some significant improvements. So while it also included initial PySide support, there wasn’t much time to make it really nice. One of the missing things was the ability to mix internal Profiler views (such as the hex editor) with PySide widgets. With the upcoming 0.9.2 release it will be possible to create a view and obtain a PySide widget with just one method:

This way one can make use of advanced internal views of the Profiler and combine them with other custom controls. Let’s see a practical example.

Mixed widget

The widget in the screenshot combines a QTreeView with a directory model and a hex view. When a file is activated in the tree, it is opened by the hex editor. To try it out, just press Ctrl+Alt+R and enter the following code:

Amazingly little code snippet, right? Please note that the ProHexView setFileName method is also a new addition to the SDK.

PySide support

This is really a small addition which took just a couple of hours of work, but since it can come very handy, it’s worth dedicating a post to it. The upcoming 0.9.1 version of the Profiler adds explicit support for PySide. Thus, it will be possible to create Qt widgets and add them to the workspace.

Installing PySide

First of all, let’s install PySide. There are 3 ways to do this.

1) Install it from the qt-project page.

Make sure you select the package matching the current Python version used by the Profiler.

2) Install the package we compiled for you. It’s vanilla, directly from the original sources, but it has the advantage that it is guaranteed to work. In fact, at the time of writing the official package contains a bug (missing shiboken Python module) and so the first one is not really an option until it is not fixed.

3) You can compile PySide yourself following the instructions at qt-project. At the end, use the installer created inside ‘c:\pyside-setup\dist’.

A code sample

Using it is even easier than the setup process. Basically ProContext has a new method called createViewFromWidget which takes as a parameter a widget created by PySide and returns a ProView which in turn can be added to the workspace.

Adding a widget to the workspace only takes the following line:

Therefore using an existing widget and adding it to the workspace is very easy. Let’s see a real-world widget like an official PySide sample: PySide/examples/effects/lighting.py. It’s sufficient to remove:

And add:

Now we can add an action to execute the code or just insert it in the custom script box (Ctrl+Alt+R) and the view will be shown like this:

To set a custom icon for the view use setWindowIcon.

As usual stay tuned as the upcoming version is going to include some major additions and significant changes.
