QText Edit can also provide a scroll bar when necessary. To unset a previously set buddy, call this function with buddy set to nullptr.Note: This function enables mouse tracking if text contains rich text. See also buddy(), set Text(), QShortcut, and set Alignment().

But after I call set Text(), although Chrome dev tools indicates the text has been changed, the UI does not reflect the change. Note: The text Interaction Flags set on the label need to include either Text Selectable By Mouse or Text Selectable By Keyboard. See Supported HTML Subset for the definition of rich text.If a buddy has been set, the buddy mnemonic key is updated from the new text. When the user presses the shortcut key indicated by this label, the keyboard focus is transferred to the label's buddy widget.For example: In this example, keyboard focus is transferred to the label's buddy (the QLine Edit) when the user presses Alt P.If the buddy was a button (inheriting from QAbstract Button), triggering the mnemonic would emulate a button click. This property holds the label's text indent in pixels If a label displays text, the indent applies to the left edge if alignment() is Qt:: Align Left, to the right edge if alignment() is Qt:: Align Right, to the top edge if alignment() is Qt:: Align Top, and to the bottom edge if alignment() is Qt:: Align Bottom.A QLabel is often used as a label for an interactive widget.

For this use QLabel provides a useful mechanism for adding an mnemonic (see QKey Sequence) that will set the keyboard focus to the other widget (called the QLabel's "buddy").This property holds the width of the margin The margin is the distance between the innermost pixel of the frame and the outermost pixel of contents. Note: The text Interaction Flags set on the label need to include either Links Accessible By Mouse or Links Accessible By Keyboard. This property holds the label's pixmap If no pixmap has been set this will return nullptr. When enabled and the label shows a pixmap, it will scale the pixmap to fill the available space. Access functions: This property holds the selected text If there is no selected text this property's value is an empty string.By default, this property contains an empty string. This property holds the label's text If no text has been set this will return an empty string. The text will be interpreted either as plain text or as rich text, depending on the text format setting; see set Text Format(). QLabel will try to auto-detect the format of the text set.If indent is negative, or if no indent has been set, the label computes the effective indent as follows: If frame Width() is 0, the effective indent becomes 0.If frame Width() is greater than 0, the effective indent becomes half the width of the "x" character of the widget's current font().I trying to use the following code to change the text in a QLabel from "Ready." to "Boo!
