Enhancing the navigation widgets by home-grown code

[j8xixo12]

The Euler1d app has been integrated with the matplotlib navigation toolbar. However, this navigation widget is a third-party dependency from matplotlib, making it difficult to customize.

We should developing a custom navigation widget from scratch to allow for full UI customization.

Navigation widget is a key feature of data visualization application, to make a home-grown navigation widget indeed requires a lot of effort, here is the development plan of nnhancing the navigation widgets by home-grown code, it will be separated into short-term and long-term part:

The short-term navigation widgets development plan:

• Add a indicator that allow mouse pointing to show mesh and solution information using native Qt (C++) on the top of current matplotlib code.

The long-term navigation widgets development plan is using native Qt (C++) to implement whole plotting system to instead of matplotlib, the development plan is:

• Implement Line and text object class that allow user to customize it (color, width and position)
• Base on home-grown Line and text object to create a plot class that draws xy-plot.
