There is a lot of overhead in the gtk_combo_box_text_insert_text
function, so adding a lot of items to a choicebox can be an expensive
operation when it is used. Instead directly access the underlying data
model and add the items to it.
Experiments show that for adding 10000 items to a wxChoice, the amount
of time spent in wxChoice::DoInsertItems for each method are:
gtk_combo_box_text_insert_text: 6.75s
gtk_list_store_insert_with_values: 438.2ms

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
This version of wxWidgets supports the following primary platforms:
- Windows 7, 8, 10 and 11 (32/64 bits).
- Most Unix variants using the GTK+ toolkit (version 2.6 or newer or 3.x).
- macOS (10.10 or newer) using Cocoa under both amd64 and ARM platforms.
All C++11 compilers are supported including but not limited to:

Please use 3.2 branch if you must use wxWidgets with a C++98 compiler or support Windows XP.
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, e.g. here are the instructions for
wxGTK, wxMSW and
wxOSX.
If you're building the sources checked out from Git, and not from a released version, please see these additional Git-specific notes.
