Member Function Documentation

OnKeyboard()

void tachyon::InputHandlerBroadcaster::OnKeyboard ( tachyon::ID id, KeyCode key, int repeat, KeyModifier modifiers, KeyAction action )

inlineoverridevirtual

A key went down or up (key is its KeyCode, repeat nonzero for an auto-repeat), or a character was typed (KeyAction::KeyChar: key holds its Unicode codepoint).

Implements tachyon::IPlatformInputHandler.

OnMouseMove()

void tachyon::InputHandlerBroadcaster::OnMouseMove ( tachyon::ID id, tachyon::int2 screenPos, tachyon::MouseButtons buttons, KeyModifier modifiers )

inlineoverridevirtual

The mouse moved over window id; screenPos in screen pixels, buttons those held down.

Implements tachyon::IPlatformInputHandler.

OnMouseButton()

void tachyon::InputHandlerBroadcaster::OnMouseButton ( tachyon::ID id, tachyon::int2 screenPos, tachyon::MouseButtons buttons, KeyModifier modifiers, tachyon::MouseAction action )

inlineoverridevirtual

A mouse button went down or up; buttons are those held down after the change.

Implements tachyon::IPlatformInputHandler.

OnMouseScroll()

void tachyon::InputHandlerBroadcaster::OnMouseScroll ( tachyon::ID id, tachyon::int2 screenPos, tachyon::float2 scrollOffset, KeyModifier modifiers )

inlineoverridevirtual

The wheel turned, by scrollOffset notches; positive y is away from the user (scrolls up).

Implements tachyon::IPlatformInputHandler.

OnTextComposition()

void tachyon::InputHandlerBroadcaster::OnTextComposition ( tachyon::ID id, std::string_view text, int32_t cursor )

inlineoverridevirtual

IME composition (pre-edit) text, UTF-8, shown but not yet committed; empty when composing ends.

cursor is the caret's codepoint offset within it. Committed text still arrives as KeyChar.

Implements tachyon::IPlatformInputHandler.

OnFileDrop()

void tachyon::InputHandlerBroadcaster::OnFileDrop ( tachyon::ID id, tachyon::int2 screenPos, FileDropAction action, std::string_view data )

inlineoverridevirtual

A drag from another application over window id: it came, moved to screenPos (screen pixels), dropped a file or text (data), or ended (dropped, or left the window).

Reimplemented from tachyon::IPlatformInputHandler.
