-/** @class wxPGProperty
+/**
+ @class wxPGProperty
wxPGProperty is base class for all wxPropertyGrid properties. In
sections below we cover few related topics.
@subsection wxPropertyCategory
Not an actual property per se, but a header for a group of properties.
- Regardless inherits from wxPGProperty.
+ Regardless inherits from wxPGProperty, and supports displaying 'labels'
+ for columns other than the first one. Easiest way to set category's
+ label for second column is to call wxPGProperty::SetValue() with string
+ argument.
@subsection wxStringProperty
Simple string property. wxPG_STRING_PASSWORD attribute may be used
to echo value as asterisks and use wxTE_PASSWORD for wxTextCtrl.
+ wxPG_ATTR_AUTOCOMPLETE attribute may be used to enable auto-completion
+ (use a wxArrayString value), and is also supported by any property that
+ happens to use a wxTextCtrl-based editor.
@remarks wxStringProperty has a special trait: if it has value of
"<composed>", and also has child properties, then its displayed
Default float-to-text precision is 6 decimals, but this can be changed
by modifying wxPG_FLOAT_PRECISION attribute.
+ Note that when displaying the value, sign is omitted if the resulting
+ textual representation is effectively zero (for example, -0.0001 with
+ precision of 3 will become 0.0 instead of -0.0). This behaviour is unlike
+ what C standard library does, but should result in better end-user
+ experience in almost all cases.
+
@subsection wxBoolProperty
Represents a boolean value. wxChoice is used as editor control, by the
- default. wxPG_BOOL_USE_CHECKBOX attribute can be set to true inorder to use
- check box instead.
+ default. wxPG_BOOL_USE_CHECKBOX attribute can be set to true in order to

@subsection wxLongStringProperty
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.
Like wxLongStringProperty, but the button triggers file selector instead.
Default wildcard is "All files..." but this can be changed by setting
wxPG_FILE_WILDCARD attribute (see wxFileDialog for format details).
- Attribute wxPG_FILE_SHOW_FULL_PATH can be set to false inorder to show
+ Attribute wxPG_FILE_SHOW_FULL_PATH can be set to @false in order to show
only the filename, not the entire path.
@subsection wxEnumProperty
@subsection wxFlagsProperty
- Represents a bit set that fits in a long integer. wxBoolProperty sub-properties
- are created for editing individual bits. Textctrl is created to manually edit
- the flags as a text; a continous sequence of spaces, commas and semicolons
- is considered as a flag id separator.
- <b>Note: </b> When changing "choices" (ie. flag labels) of wxFlagsProperty, you
- will need to use wxPGProperty::SetChoices() - otherwise they will not get updated
- properly.
