Struct winsafe::gui::Label

pub struct Label(_);

Native label control.

Implements Child trait.

Implementations

impl Label

pub fn new(parent: &dyn Parent, opts: LabelOpts) -> Label

Instantiates a new Label object, to be created on the parent window with HWND::CreateWindowEx.

pub fn new_dlg(parent: &dyn Parent, ctrl_id: u16) -> Label

Instantiates a new CheckBox object, to be loaded from a dialog resource with HWND::GetDlgItem.

pub fn hwnd(&self) -> HWND

Returns the underlying handle for this control.

Note: the handle is initially null, receiving an actual value only after the control is physically created, what usually happens right before WM_CREATE or WM_INITDIALOG events.

pub fn ctrl_id(&self) -> u16

Returns the control ID.

pub fn on_subclass(&self) -> &WindowEvents

Exposes the subclass events. If at least one event exists, the control will be subclassed.

Note: Subclassing may impact performance, use with care.

Panics

Panics if the control or the parent window are already created. Events must be set before control and parent window creation.

pub fn on(&self) -> &LabelEvents

Exposes the control events.

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

Panics

Panics if the control or the parent window are already created. Events must be set before control and parent window creation.

pub fn resize_to_text(&self) -> WinResult<()>

Resizes the control to exactly fit current text.

pub fn set_text(&self, text: &str) -> WinResult<()>

Sets the text by calling SetWindowText.

Examples

use winsafe::gui;

let my_label: gui::Label; // initialized somewhere

my_label.set_text("This my text")?;

pub fn set_text_and_resize(&self, text: &str) -> WinResult<()>

Calls set_text and resizes the control to exactly fit the new text.

Examples

use winsafe::gui;

let my_label: gui::Label; // initialized somewhere

my_label.set_text_and_resize("This my text")?;

pub fn text(&self) -> WinResult<String>

Retrieves the text in the control by calling HWND::GetWindowText.

Examples

use winsafe::gui;

let my_label: gui::Label; // initialized somewhere

println!("The text is: {}", my_label.text()?);
