Struct winsafe::gui::events::ButtonEvents

pub struct ButtonEvents { /* fields omitted */ }

Exposes button control notifications.

These event methods are just proxies to the WindowEvents of the parent window, who is the real responsible for the child event handling.

You cannot directly instantiate this object, it is created internally by the control.

Implementations

pub fn bcn_drop_down<F>(&self, func: F) where
    F: Fn(&NMBCDROPDOWN) -> BoxResult<()> + 'static, 

BCN_DROPDOWN notification.

Sent when the user clicks a drop down arrow on a button.

pub fn bcn_hot_item_change<F>(&self, func: F) where

BCN_HOTITEMCHANGE notification.

Notifies the button control owner that the mouse is entering or leaving the client area of the button control.

pub fn bn_clicked<F>(&self, func: F) where
    F: Fn() -> BoxResult<()> + 'static,

Examples

use winsafe::{gui, BoxResult};

let btn: gui::Button; // initialized somewhere

btn.on().bn_clicked({
    let btn = btn.clone(); // pass into the closure
    move || -> BoxResult<()> {
        println!("HWND: {}", btn.hwnd());
        Ok(())
    }
});

pub fn bn_dbl_clk<F>(&self, func: F) where
    F: Fn() -> BoxResult<()> + 'static,

    F: Fn() -> BoxResult<()> + 'static, 

BN_KILLFOCUS command notification.

Sent when a button loses the keyboard focus. The button must have the BS::NOTIFY style to send this notification code.

pub fn bn_set_focus<F>(&self, func: F) where
    F: Fn() -> BoxResult<()> + 'static, 

BN_SETFOCUS command notification.

Sent when a button receives the keyboard focus. The button must have the BS::NOTIFY style to send this notification code.

pub fn nm_custom_draw<F>(&self, func: F) where
    F: Fn(&NMCUSTOMDRAW) -> BoxResult<CDRF> + 'static,
