Detailed Description
An icon-only button for showing contextually relevant help or explanations.
KContextualHelpButton allows hiding text of any length behind a small icon-only button. Hovering over the button with a mouse cursor or pressing the button will show the text. It can contain images and links. It is accessible by keyboard and to screen readers.
When to Use
Sometimes users require help or an explanation, even experts. This help should be readily available exactly where and when a user needs it. A KContextualHelpButton makes clear that inline help is available without really cluttering up the user interface. In that sense it is superior to setting tooltips which are completely invisible until invoked and therefore easy to miss. Especially for touch users the KContextualHelpButton is preferable.
When Not to Use
If the text is important for the user to understand and can be kept very short, place it inline below the control it affects. If there is no room to put this KContextualHelpButton, use QWidget::setToolTip() for shorter texts and QWidget::SetWhatsThis() for longer text or text that should contain hyperlinks. If your software is not already using the KXmlGui framework, consider using KToolTipHelper from KXmlGui to make the whatsThis() help more discoverable.
How to Use
The most simple way is creating it like any other button and then setting the help text:
The most common use of this component might be on settings pages which oftentimes use a QFormLayout. Here is an example on how to use it next to a QCheckBox. Unfortunately we need to make the KContextualHelpButton aware of the QCheckBox here or it will increase the height of the row in the QFormLayout which might look bad. The help text in this example contains an image and a working hyperlink:
This class is meant to be kept somewhat consistent with the QML equivalent which is also called ContextualHelpButton.
