dialog. Note that in long string values, tabs are represented by "\t" and
line break by "\n".
+ To display custom dialog on button press, you can subclass
+ wxLongStringProperty and implement OnButtonClick, like this:
+
+ @code
+ virtual bool OnButtonClick( wxPropertyGrid* propGrid, wxString& value )
+ {
+ wxSize dialogSize(...size of your dialog...);
+
+ wxPoint dlgPos = propGrid->GetGoodEditorDialogPosition(this,
+ dialogSize)
+
+ // Create dialog dlg at dlgPos. Use value as initial string
+ // value.
+ ...
+
+ if ( dlg.ShowModal() == wxID_OK )
+ {
+ value = dlg.GetStringValue);
+ return true;
+ }
+ return false;
+ }
+ @endcode
+
+ Also, if you wish not to have line breaks and tabs translated to
+ escape sequences, then do following in constructor of your subclass:
+
+ @code
+ m_flags |= wxPG_PROP_NO_ESCAPE;
+ @endcode
+
@subsection wxDirProperty
Like wxLongStringProperty, but the button triggers dir selector instead.
<b>Useful alternate editor:</b> Choice.

+ There are various sub-classing opportunities with this class. See
+ below in wxSystemColourProperty section for details.
@subsection wxFontProperty
Represents wxColour and a system colour index. wxChoice is used to edit
the value. Drop-down list has color images. Note that value type

@code
class wxColourPropertyValue : public wxObject
{
wxColour m_colour;
};
@endcode
+
+ in wxSystemColourProperty, and its derived class wxColourProperty, there
+ are various sub-classing features. To set basic list list of colour
+ names, call wxPGProperty::SetChoices().

+ // to strings.
