+@section propgrid_tooltipandhint Help String, Hint and Tool Tips
+
+For each property you can specify two different types of help text. First,
+you can use wxPropertyGridInterface::SetPropertyHelpString() or
+wxPGProperty::SetHelpString() to set property's help text. Second, you
+can use wxPGProperty::SetAttribute() to set property's "Hint" attribute.
+
+Difference between hint and help string is that the hint is shown in an empty
+property value cell, while help string is shown either in the description text
+box, as a tool tip, or on the status bar, whichever of these is available.
+
+To enable display of help string as tool tips, you must explicitly use
+the wxPG_EX_HELP_AS_TOOLTIPS extra window style.
