Detailed Description

Hotkey handler structure.

The PtHotkeyCallback_t structure lets you specify hotkeys or hotkey handlers, or both, for various widgets. This structure contains at least:

Members

‍unsigned short key_sym_cap Depending on the specified flags, this member contains either the symbol or cap of the key to be interpreted as a hotkey. For valid key_sym_cap values, see <photon/PkKeyDef.h>.

‍short flags Determines how key_sym_cap is interpreted and whether or not key_mods is used.

‍unsigned long key_mods Key modifiers that must be active for the key to be considered a hotkey.

‍PtWidget_t *widget If event_f is NULL, the widget member's activate callback is invoked with a reason_subtype of Pt_CB_HOTKEY. If the widget member is NULL when the hotkey is attached, it's set to the widget that the hotkey is attached to.

‍void *data A pointer to any data that you want to pass as the second argument to the callback function.

‍int (*event_f)( PtWidget_t *, void *, PtCallbackInfo_t * ) A pointer to the hotkey function. If event_f is NULL when the hotkey is activated, the widget that the hotkey is attached to has its PhWidgets::Basic::Activate invoked with a reason_subtype of Pt_CB_HOTKEY.
