Struct Cursor

pub struct Cursor {
    pub icon: CursorIcon,
    pub visible: bool,
    pub grab_mode: CursorGrabMode,
    pub hit_test: bool,
}

Cursor data for a Window.

Fields

icon: CursorIcon

What the cursor should look like while inside the window.

visible: bool

Whether the cursor is visible or not.

Platform-specific

• Windows, X11, and Wayland: The cursor is hidden only when inside the window. To stop the cursor from leaving the window, change Cursor::grab_mode to CursorGrabMode::Locked or CursorGrabMode::Confined
• macOS: The cursor is hidden only when the window is focused.
• iOS and Android do not have cursors

grab_mode: CursorGrabMode

Whether or not the cursor is locked by or confined within the window.

Platform-specific

• Windows doesn’t support CursorGrabMode::Locked
• macOS doesn’t support CursorGrabMode::Confined
• iOS/Android don’t have cursors.

Since Windows and macOS have different CursorGrabMode support, we first try to set the grab mode that was asked for. If it doesn’t work then use the alternate grab mode.

hit_test: bool

Set whether or not mouse events within this window are captured or fall through to the Window below.

Platform-specific

• iOS / Android / Web / X11: Unsupported.
