Types

type IHandler

type IHandler interface {
	OnCreate()
	OnRequestClose() bool
	OnDestroy()
	OnActivate(active bool)
	OnAppear(visible bool)
	OnResize(width, height float32)
	OnMouseMove(x, y float32)
	OnMousePress(btn int, x, y float32)
	OnMouseRelease(btn int, x, y float32)
	OnMouseWheel(axis int, delta, x, y float32) // up is positive
	OnMouseEnter(x, y float32)
	OnMouseLeave(x, y float32)
	OnExpose(x, y, width, height float32)
}

IHandler is a complete Handler interface, for document purpose.

type SysSpecial

type SysSpecial struct {
	// contains filtered or unexported fields
}

type Window

type Window struct {
	WindowHandle

	Handler interface{}

	SysSpecial
	// contains filtered or unexported fields
}

Window represent a native window, it wraps a HWND on Windows, XCB visual or XLib Window on Linux, NSView on MacOS.
