What We Know About QTextEdit - russ-hensel/qt5_by_example GitHub Wiki

A line edit or QTextEdit is a more or less rectangular area on a GUI that typically:

• has space for user input and is use for that
• has multiple lines

It is a lot like a QLineEdit, but that widget is for a single line.

Now we will look deeper into the topic of QTextEdits, and talk a bit about how buttons share many features with many other widgets.

After a widget is created we can change may of its characteristics ( and some of these can also be set up in its init, but changing at a later runtime is more general )

These characteristics are part of the widgets state. Some related to appearance. For example:

• size
• font
• colors

Others are related to user actions the widget can detect and act on

• return pressed
• get focus

Different widget may have different appearance and action states, depending on their intended use.

The code for the tab is: ..... but is better viewed in your own IDE.

Interaction to try on this tab:

• enter and edit text
• hover look for tool tips
• poke around -- do not forget to look at the gui

To see and change the state use the mutate/examine button and read the code in the mutate_x methods.
the documentation is in the code. Coverage is not complete, work continues.

You can use the wat-inspect to find out more or dive into the documentation which is all over the web.
