Struct x11rb::properties::WmClass

source ·
pub struct WmClass(/* private fields */);
Expand description

The value of a window’s WM_CLASS property.

Usage example:

use x11rb::connection::Connection;
use x11rb::errors::ConnectionError;
use x11rb::properties::WmClass;
use x11rb::protocol::xproto::Window;

fn print_class_instance(
    conn: &impl Connection,
    window: Window,
) -> Result<bool, ConnectionError> {
    let wm_class = match WmClass::get(conn, window)?.reply_unchecked()? {
        Some(wm_class) => wm_class,
        None => return Ok(false), // Getting the property failed
    };
    // Note that the WM_CLASS property is not actually encoded in utf8.
    // ASCII values are most common and for these from_utf8() should be fine.
    let class = std::str::from_utf8(wm_class.class());
    let instance = std::str::from_utf8(wm_class.instance());
    println!(
        "For window {:x}, class is '{:?}' and instance is '{:?}'",
        window, class, instance,
    );
    Ok(true)
}

Implementations§

source§

impl WmClass

source

pub fn get<C: RequestConnection>( conn: &C, window: Window ) -> Result<WmClassCookie<'_, C>, ConnectionError>

Send a GetProperty request for the WM_CLASS property of the given window

source

pub fn from_reply(reply: GetPropertyReply) -> Result<Option<Self>, ParseError>

Construct a new WmClass instance from a GetPropertyReply.

The original GetProperty request must have been for a WM_CLASS property for this function to return sensible results.

source

pub fn instance(&self) -> &[u8]

Get the instance contained in this WM_CLASS property

source

pub fn class(&self) -> &[u8]

Get the class contained in this WM_CLASS property
