Further you can also set status tips and short cuts for each action. Once the skeleton is ready you can add many functionalities such as font name,font colour,cut,copy,paste,open etc.
The idea behind developing the GUI revolves around the functionalities that you desire.Basically any editor or any application in general will have three bars- Format bar,toolbar and menu bar.These can be set up very easily in PyQt using built in methods.PyQt supports both menu bar and toolbar.Further you can set up names,contents and positions. Of these for GUI development we use QtGui.It contains graphical components such as buttons, windows, status bars, toolbars, sliders, bitmaps, colours, and fonts.

You can easily install PyQt4 (which I used) with the following command sudo apt - get install python - qt4 Popular alternatives are PySide, PyGTK, wxPython, and Tkinter.

The field e6 shows a default text, which cannot be edited as it is set to read only.Į2.setValidator(QDoubleValidator(0.99,99.I was always curious about developing a GUI for an application.In the summer that passed by I got myself hooked to various tutorials about this.That’s when I came across Pythons PyQt.

When you press ‘Enter’ or the field loses focusĪs text in the box changes either by input or by programmatic means Given below are the most commonly used methods of signals. QLineEdit object emits the following signals − QRegexpValidator − Checks input against a Regex expressionĪpplies mask of combination of characters for input QDoubleValidator − Fraction part of number limited to specified decimals QIntValidator − Restricts input to integer For example, use Ctrl + C for Copy, Ctrl + V for Paste, Ctrl + X for Cut, and so on.
