Struct PopupWindow 

pub struct PopupWindow { /* private fields */ }

A popup: a window next to the widget that opened it, sized to fit its one child. Open one with Cx::open_popup.

use crabshell_ui::{Button, PopupWindow, Text};

let button = Button::new(Text::new("open")).on_click(|cx| {
    cx.open_popup(|_cx| PopupWindow::new().child(Text::new("hello")))
});

Implementations

impl PopupWindow

pub fn new() -> PopupWindow

An empty popup.

pub fn style(self, style: impl IntoProp<Style>) -> PopupWindow

Sets the popup’s style. Its color and font are inherited by every Text in it that doesn’t set its own.

pub fn child(self, child: impl Widget) -> PopupWindow

Sets the popup’s one child. The popup is as large as the child wants to be, plus the style’s padding.

pub fn edges(self, edges: impl IntoProp<Anchors>) -> PopupWindow

Sets the edge or corner of the widget the popup hangs from, such as Edge::Bottom | Edge::Left; opposite edges cancel. Read when it opens, as the compositor places a popup once.

pub fn gravity(self, gravity: impl IntoProp<Anchors>) -> PopupWindow

Sets which way the popup extends from its edges, such as Edge::Bottom | Edge::Right. Read when it opens.

pub fn adjustment(self, adjustment: impl IntoProp<Adjust>) -> PopupWindow

Sets how the popup may move or shrink to stay on its output. The default flips and slides it. Read when it opens.

pub fn mask(self, mask: impl IntoProp<Option<Region>>) -> PopupWindow

Sets the part of the popup that takes pointer input, as PanelWindow::mask does, and None, the default, is the whole popup. A popup a click opened holds the pointer, so a click outside its mask reaches the shell’s own window below, but over another program it closes the popup, as any click outside does.

pub fn compositor_opacity(self, opacity: impl IntoProp<f32>) -> PopupWindow

Sets the opacity the compositor shows the whole popup at, blur included, as PanelWindow::compositor_opacity does.

pub fn visible_mask(self, region: impl IntoProp<Option<Region>>) -> PopupWindow

Tells the compositor which part of the popup holds anything to see, as PanelWindow::visible_mask does.
