Struct druid::WindowDesc

pub struct WindowDesc<T> {
    pub id: WindowId,
    // some fields omitted
}

A description of a window to be instantiated.

This includes a function that can build the root widget, as well as other window properties such as the title.

Fields

id: WindowId

The WindowId that will be assigned to this window.

This can be used to track a window from when it is launched and when it actually connects.

Implementations

impl<T: Data> WindowDesc<T>

pub fn new<W, F>(root: F) -> WindowDesc<T> where
    W: Widget<T> + 'static,
    F: FnOnce() -> W + 'static, 

Create a new WindowDesc, taking a function that will generate the root Widget for this window.

It is possible that a WindowDesc can be reused to launch multiple windows.

pub fn title(self, title: impl Into<LabelText<T>>) -> Self

Set the title for this window. This is a LabelText; it can be either a String, a LocalizedString, or a closure that computes a string; it will be kept up to date as the application's state changes.

pub fn menu(self, menu: MenuDesc<T>) -> Self

Set the menu for this window.

pub fn window_size(self, size: impl Into<Size>) -> Self

Set the window's initial drawing area size in display points.

You can pass in a tuple (width, height) or a Size, e.g. to create a window with a drawing area 1000dp wide and 500dp high:

window.window_size((1000.0, 500.0));

The actual window size in pixels will depend on the platform DPI settings.

This should be considered a request to the platform to set the size of the window. The platform might increase the size a tiny bit due to DPI.

pub fn with_min_size(self, size: impl Into<Size>) -> Self

Set the window's minimum drawing area size in display points.

The actual minimum window size in pixels will depend on the platform DPI settings.

This should be considered a request to the platform to set the minimum size of the window. The platform might increase the size a tiny bit due to DPI.

To set the window's initial drawing area size use window_size.

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

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