From 501358073ba90c87257dd2c3a48a429f9c004f19 Mon Sep 17 00:00:00 2001 From: Vadim Zeitlin Date: Tue, 6 Apr 2010 18:46:24 +0000 Subject: [PATCH] Move SendTextUpdatedEvent() down to wxTextEntryBase from wxTextCtrlBase. This will allow reusing it in wxComboBox implementation as well. Also add SendTextUpdatedEventIfAllowed() which can be used to only send the events if they were not blocked at wxTextEntry level. No real changes otherwise. git-svn-id: https://svn.wxwidgets.org/svn/wx/wxWidgets/trunk@63880 c3d73ce0-8a6f-49c7-b76d-6d57e0e08775 --- include/wx/textctrl.h | 5 ----- include/wx/textentry.h | 29 +++++++++++++++++++++++++++-- src/cocoa/textctrl.mm | 10 +--------- src/common/textcmn.cpp | 19 ------------------- src/common/textentrycmn.cpp | 21 +++++++++++++++++++++ src/univ/textctrl.cpp | 3 +-- 6 files changed, 50 insertions(+), 37 deletions(-) diff --git a/include/wx/textctrl.h b/include/wx/textctrl.h index af00d41d06..d9a6090ae7 100644 --- a/include/wx/textctrl.h +++ b/include/wx/textctrl.h @@ -665,11 +665,6 @@ public: virtual bool EmulateKeyPress(const wxKeyEvent& event);
