+ @class wxPGProperty
wxPGProperty is base class for all wxPropertyGrid properties. In
sections below we cover few related topics.
Simple string property. wxPG_STRING_PASSWORD attribute may be used
to echo value as asterisks and use wxTE_PASSWORD for wxTextCtrl.
- @remarks
- * wxStringProperty has a special trait: if it has value of "<composed>",
- and also has child properties, then its displayed value becomes
- composition of child property values, similar as with wxFontProperty,
- for instance.
+ @remarks wxStringProperty has a special trait: if it has value of
+ "<composed>", and also has child properties, then its displayed
+ value becomes composition of child property values, similar as
+ with wxFontProperty, for instance.
@subsection wxIntProperty
Like wxStringProperty, but converts text to a signed long integer.
wxIntProperty seamlessly supports 64-bit integers (ie. wxLongLong).
+ To safely convert variant to integer, use code like this:
+
+ @code
+ wxLongLong ll;
+ ll << property->GetValue();
+
+ // or
+ wxLongLong ll = propertyGrid->GetPropertyValueAsLong(property);
+ @endcode
@subsection wxUIntProperty
To set the globally used base, manipulate wxPG_UINT_BASE int
attribute. Regardless of current prefix, understands (hex) values starting
with both "0x" and "$".
- wxUIntProperty seamlessly supports 64-bit unsigned integers (ie. wxULongLong).
+ Like wxIntProperty, wxUIntProperty seamlessly supports 64-bit unsigned
+ integers (ie. wxULongLong). Same wxVariant safety rules apply.
@subsection wxFloatProperty
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 inorder to show
only the filename, not the entire path.
@subsection wxEnumProperty
<b>Useful alternate editor:</b> Choice.
Represents wxColour. wxButton is used to trigger a colour picker dialog.
+ There are various sub-classing opportunities with this class. See
+ below in wxSystemColourProperty section for details.
@subsection wxFontProperty

the value. Drop-down list has color images. Note that value type
