From: Vadim Zeitlin Date: Sat, 7 Jan 2012 15:09:43 +0000 (+0000) Subject: Implement best size calculation for report mode wxListCtrl. X-Git-Url: https://git.saurik.com/wxWidgets.git/commitdiff_plain/94248d2ed19bb207a49cf1a5bd9bfea0fd04760b Implement best size calculation for report mode wxListCtrl. Use the column labels to determine the minimal width required by the control to show them all in full. Also declare all image list and column-related wxListCtrl methods in wxListCtrlBase now as we need some of them in DoGetBestClientSize() implementation. git-svn-id: https://svn.wxwidgets.org/svn/wx/wxWidgets/trunk@70282 c3d73ce0-8a6f-49c7-b76d-6d57e0e08775 --- diff --git a/docs/changes.txt b/docs/changes.txt index d36572119a..7bf55bb1f9 100644 --- a/docs/changes.txt +++ b/docs/changes.txt @@ -465,6 +465,7 @@ All (GUI): - Allow using wxEVT_UPDATE_UI with wxRibbonButtonBar (Emilien Kia). - Add wxRibbonButtonBar::InsertXXXButton() methods (Emilien Kia). - Fix multiple item selection in generic wxTreeCtrl (Igor Korot). +- Implement best size calculation for report mode wxListCtrl.
