Woopsi is a Nintendo DS GUI library for rapidly creating user interfaces for homebrew software. Modelled after the AmigaOS windowing system.

Release notes:

Version 0.35 is now out. Changes are listed below. The most significant changes this time around include the addition of a keyboard gadget for text input, cursor support in the TextBox gadget and re-written VBL integration to use a much simpler timer gadget for VBL-based code.

I’ve attached a screenshot of the keyboard. It has shift, caps lock and control modifier keys, and the full 7-bit ASCII set of symbols (ie. a fairly standard American keyboard layout).

There are two new example projects. One illustrates how to use the new timer, whilst the other shows how to use the keyboard.

– Fixes:
– Renamed “Textbox” to “TextBox”.
– Corrected case of “PackedFontBase.h” include in “packedfontbase.cpp” (thanks Gattman, bug 2101099).
– Removed offcolour pixels from around @ symbol in sysfont bitmap.
– Moved @ symbol in tinyfont.bmp to correct ASCII location.
– SkinnedWindows move to front when clicked.
– Renamed TextBox::TextPositionXXX to TextAlignmentXXX, along with all related functions and similar in MultiLineTextBox and ScrollingTextBox.
