From 7197bbad212b0d2e4c0986a2875cba566510f30d Mon Sep 17 00:00:00 2001 From: Jaakko Salli Date: Sun, 25 Jul 2010 10:36:19 +0000 Subject: [PATCH] Refactored validation of numeric properties (wxIntProperty, wxUIntProperty and wxFloatProperty). They now use (basically) a single template function instead of three separate ones. git-svn-id: https://svn.wxwidgets.org/svn/wx/wxWidgets/trunk@65098 c3d73ce0-8a6f-49c7-b76d-6d57e0e08775 --- include/wx/propgrid/props.h | 4 +- src/propgrid/props.cpp | 152 +++++++++++++----------------------- 2 files changed, 55 insertions(+), 101 deletions(-) diff --git a/include/wx/propgrid/props.h b/include/wx/propgrid/props.h index 114f42a455..daa5462403 100644 --- a/include/wx/propgrid/props.h +++ b/include/wx/propgrid/props.h @@ -122,9 +122,9 @@ protected: // ----------------------------------------------------------------------- -/** Constants used with DoValidation() methods. +/** Constants used with NumericValidation<>(). */ -enum wxPGDoValidationConstants +enum wxPGNumericValidationConstants { /** Instead of modifying the value, show an error message. */ diff --git a/src/propgrid/props.cpp b/src/propgrid/props.cpp index ae059f0e69..755a79f1a3 100644 --- a/src/propgrid/props.cpp +++ b/src/propgrid/props.cpp @@ -261,11 +261,22 @@ bool wxIntProperty::IntToValue( wxVariant& variant, int value, int WXUNUSED(argF return false;
