Václav Slavík e5beb4e93f Improve wxDataViewMainWindow::RefreshRow speed
RefreshRow() is called very frequently, and in particular after every
ItemChanged notification. Calling GetEndOfLastCol() in it repeatedly is
extremely inefficient in presence of auto-sizing columns, and doesn't
make much sense anyway - controls with significant space unoccupied by
columns are rare, and rendering of such unused space is efficient (just
background erase). It is therefore more performant to simply refresh
the entire row instead of repeatedly and expensively calculating the
smallest rectangle that needs repainting.

Fixes previously wrong calculation of the refreshed rectangle in
RefreshRows() in the process.

Fixes major performance regression introduced in
77c7c80696.

About

wxWidgets is a free and open source cross-platform C++ framework for writing advanced GUI applications using native controls.

wxWidgets Logo

wxWidgets allows you to write native-looking GUI applications for all the major desktop platforms and also helps with abstracting the differences in the non-GUI aspects between them. It is free for the use in both open source and commercial applications, comes with the full, easy to read and modify, source and extensive documentation and a collection of more than a hundred examples. You can learn more about wxWidgets at https://www.wxwidgets.org/ and read its documentation online at https://docs.wxwidgets.org/

Platforms

AppVeyor Travis

wxWidgets currently supports the following primary platforms:

  • Windows XP, Vista, 7, 8 and 10 (32/64 bits).
  • Most Unix variants using the GTK+ toolkit (version 2.6 or newer or 3.x).
  • OS X (10.7 or newer) using Cocoa (32/64 bits).

Most popular C++ compilers are supported including but not limited to:

  • Microsoft Visual C++ 2003 or later (up to 2017).
  • g++ 3.4 or later, including MinGW/MinGW-64/TDM under Windows.
  • Clang under OS X and Linux.
  • Intel icc compiler.
  • Oracle (ex-Sun) aCC.

Licence

wxWidgets licence is a modified version of LGPL explicitly allowing not distributing the sources of an application using the library even in the case of static linking.

Building

For building the library, please see platform-specific documentation under docs/<port> directory.

If you're building the sources checked out from Git, and not from a released versions, please see these additional Git-specific notes.
