Function documentation

bool destroyed() const

Returns whether the window is marked for destruction.

This is set either from a callback, or by calling dip::viewer::Window::destroy.

dip::uint drawString(char const* string)

Draw a string onto the window.

Must be called from a callback.

void title(char const* name) protected

Sets the window’s title.

Must be called from a callback.

void swap() protected

Swaps display buffers.

Must be called from a callback.

void requestSize(dip::uint width, dip::uint height) protected

Suggests a window’s size.

Note that this function must be called before the dip::viewer::Window::create callback is called.

void id(void* _id) private

Sets the window’s identity.

This should be called by the window’s manager in order to set a unique identifier that can be used to determine the window context.

void resize(int width, int height) private

Sets the window’s size.

Note that this does not actually resize the window!
