Method: Ruber::ExceptionDialog::ExceptionBacktraceWidget#sizeHint

Defined in:
lib/ruber/exception_widgets.rb

#sizeHint ⇒ Qt::Size

Override of @KDE::TextEdit#sizeHint@

The width is computed as the size (using the fixed width font) of the longest line, while the height is computed as the height of a single line multiplied by the number of lines.

Both width and height are computed using @Qt::FontMetrics@

Returns:

  • (Qt::Size) —

    the suggested size of the widget
