Struct native_windows_gui::Notice [−][src]
pub struct Notice { pub handle: ControlHandle, }
Expand description
An invisible component that can be triggered by other thread.
A notice object does not send data between threads. Rust has already plenty of way to do this. The notice object only serve to “wake up” the GUI thread.
A notice must have a parent window. If the parent is destroyed before the notice, the notice becomes invalid.
Requires the notice
feature.
Example
use native_windows_gui as nwg; fn build_notice(notice: &mut nwg::Notice, window: &nwg::Window) { nwg::Notice::builder() .parent(window) .build(notice); }
use native_windows_gui as nwg; use std::thread; use std::time; fn notice(noticer: &nwg::Notice) { let sender = noticer.sender(); thread::spawn(move || { thread::sleep(time::Duration::new(5, 0)); sender.notice(); }); }
Fields
handle: ControlHandle
Implementations
A shortcut over the builder API for the notice object
Checks if the notice is still usable. A notice becomes unusable when the parent window is destroyed. This will also return false if the notice is not initialized.
Return an handle to the notice window or None
if the window was destroyed.
Change the parent window of the notice. This won’t update the NoticeSender already created. Panics if the control is not a window-like control or if the notice was not initialized
Create a new NoticeSender
bound to this Notice
