The Python editor

The App Designer contains a basic Python Editor:

Figure 67: The Python editor

This editor contains some basic functions such as:

• Syntax highlighting

• Line numbering

• White space display

• Indenting and auto-indenting

• Commenting

• Go to line

• Search and replace

• Undo/Redo

The regular expression syntax used by the search and replace functionality is the one provided by the Qt QRegularExpression class. Its documentation is available here: Qt 6.5/QRegularExpression.

The captured text can be used in the Replace field, by using &, \0, \1, etc.

& represents the entire search string (evaluated)

\0 represents the entire search string (evaluated), just like &

\1 represents the first captured text

\2 represents the second captured text, etc.
