From 5833988cb7a092f9976c1fb2320d4013f825400a Mon Sep 17 00:00:00 2001 From: Vadim Zeitlin Date: Mon, 10 Jun 2013 15:53:29 +0000 Subject: [PATCH] Add wxMouseEvent::GetColumnsPerAction(). This is similar to the existing GetLinesPerAction() but is for, surprise, columns. Also change the documentation to say that the value returned by both of these methods is 3 under "most platforms" as some wxOSX currently uses 1 and not 3. Closes #15239. git-svn-id: https://svn.wxwidgets.org/svn/wx/wxWidgets/trunk@74156 c3d73ce0-8a6f-49c7-b76d-6d57e0e08775 --- docs/changes.txt | 1 + include/wx/event.h | 7 ++++++- include/wx/msw/missing.h | 3 +++ interface/wx/event.h | 18 +++++++++++++++++- src/common/event.cpp | 2 ++ src/gtk/window.cpp | 1 + src/gtk1/window.cpp | 1 + src/msw/window.cpp | 13 +++++++++++++ src/osx/carbon/nonownedwnd.cpp | 1 + src/osx/cocoa/window.mm | 1 + src/x11/window.cpp | 1 + 11 files changed, 47 insertions(+), 2 deletions(-) diff --git a/docs/changes.txt b/docs/changes.txt index 3093cd0..4cd8f39 100644 --- a/docs/changes.txt +++ b/docs/changes.txt @@ -670,6 +670,7 @@ All (GUI): - Add wxWindow::BeginRepositioningChildren() and EndRepositioningChildren(). - Fix wxStyledTextCtrl::SetInsertionPointEnd() (troelsk). - Add wxFileDialog::GetCurrentlySelectedFilename() (Carl Godkin). +- Add wxMouseEvent::GetColumnsPerAction() (toiffel). wxGTK: diff --git a/include/wx/event.h b/include/wx/event.h index 87a1a6a..38303aa 100644 --- a/include/wx/event.h +++ b/include/wx/event.h @@ -1747,9 +1747,13 @@ public: wxMouseWheelAxis GetWheelAxis() const { return m_wheelAxis; } // Returns the configured number of lines (or whatever) to be scrolled per - // wheel action.
