Keyboard Codes
The table below shows the IUP codification of every key in the keyboard. Each key is represented by an integer value, defined in the iupkey.h file, which must be included in the application. Normally these keys are used in K_ANY and KEYPRESS_CB callbacks to inform the key that was pressed in the keyboard.
IUP uses the US default codification this means that if you installed a keyboard specific for your country the key codes will be different from the real keys for a small group of keys. Except for the Brazilian ABNT keyboard which works in Windows and Linux. This does not affect the IupText and IupMultiline text input.
Notice that somes key combinations are not available, like: Shift+Ins, Shift+Del, Alt+Space, Alt/Ctrl/Shift+Backspace, Alt/Ctrl/Shift+Pause, Alt/Ctrl/Shift+Esc, Ctrl/Alt+Enter. When CapsLock is active the Shift+<Key> combination is used, except for Esc and Backspace that will ignore the combination.
The
isxkey(key)macro defined in the <iupkey.h> file informs whether a given key is an extended code instead of an alphanumeric key. This macro is also available in Lua as a function with the same name.In IUP the codification implies that some keys have the same code: K_BS=K_cH, K_TAB=K_cI and K_CR=K_cM.
