InformFirstDirection() is required to let wxWrapSizer calculate its best height from its current width (or vice versa, but usually in this sense), but it only worked if wxWrapSizer was an immediate child of another size doing layout but not if wxWrapSizer was inside another wxBoxSizer which was contained in a top-level sizer. Explicitly forward calls to InformFirstDirection() to wxBoxSizer children to fix this and make wxWrapSizers nested in wxBoxSizer work. Note that there are still many problems in this code, including but not limited to: - Doing this forwarding for the sizer minor direction only. - Not passing the correct value of "availableOtherDir". - Still calling InformFirstDirection() from RecalcSizes(), when it's too late to change the min size returned by CalcMin(). - Inconsistency: wxGridSizer calls InformFirstDirection() from its CalcMin(), wxFlexGridSizer calls it from its RecalcSizes(), wxGridBagSizer doesn't call it at all. All this size-in-first-direction logic really needs to be completely reviewed, but for now at least make wxWrapSizer inside a wxBoxSizer work as well, or as badly, as wxWrapSizer on its own.
About
wxWidgets is a free and open source cross-platform C++ framework for writing advanced GUI applications using native controls.
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
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:
