Builder for a window

Implementations

impl<'a> Window<'a>

pub fn new(name: &ImStr) -> Window

Creates a new window builder with the given name

pub fn opened(self, opened: &'a mut bool) -> Self

Enables the window close button, which sets the passed boolean to false when clicked

pub fn flags(self, flags: WindowFlags) -> Self

Replace current window flags with the given value

pub fn position(self, position: [f32; 2], condition: Condition) -> Self

Sets the window position, which is applied based on the given condition value

pub fn position_pivot(self, pivot: [f32; 2]) -> Self

Sets the window position pivot, which can be used to adjust the alignment of the window relative to the position.

For example, pass [0.5, 0.5] to center the window on the position. Does nothing if window position is not also set with position().

pub fn size(self, size: [f32; 2], condition: Condition) -> Self

Sets the window size, which is applied based on the given condition value

pub fn size_constraints(self, size_min: [f32; 2], size_max: [f32; 2]) -> Self

Sets window size constraints.

Use -1.0, -1.0 on either X or Y axis to preserve current size.

pub fn content_size(self, size: [f32; 2]) -> Self

Sets the window content size, which can be used to enforce scrollbars.

Does not include window decorations (title bar, menu bar, etc.). Set one of the values to 0.0 to leave the size automatic.

pub fn collapsed(self, collapsed: bool, condition: Condition) -> Self

Sets the window collapse state, which is applied based on the given condition value

pub fn focused(self, focused: bool) -> Self

Sets the window focused state, which can be used to bring the window to front

pub fn bg_alpha(self, bg_alpha: f32) -> Self

Sets the background color alpha value.

When enabled, appends '*' to title without affecting the ID, as a convenience.

Disabled by default.

pub fn no_nav(self) -> Self

Disable gamepad/keyboard navigation and focusing.

Shorthand for

.nav_inputs(false)
.nav_focus(false)

pub fn no_decoration(self) -> Self

#[must_use]pub fn begin(self, ui: &Ui) -> Option<WindowToken>

Creates a window and starts appending to it.

Returns Some(WindowToken) if the window is visible. After content has been rendered, the token must be ended by calling .end().

Returns None if the window is not visible and no content should be rendered.

pub fn build<F: FnOnce()>(self, ui: &Ui, f: F)

Creates a window and runs a closure to construct the contents.

Note: the closure is not called if no window content is visible (e.g. window is collapsed or fully clipped).
