Expand description

This trait is enabled with the user feature, and provides methods for HINSTANCE.

Prefer importing this trait through the prelude:

use winsafe::prelude::*;

Provided Methods§

source

unsafe fn CreateDialogParam( &self, resource_id: IdStr, hwnd_parent: Option<&HWND>, dialog_proc: DLGPROC, init_param: Option<isize> ) -> SysResult<HWND>

CreateDialogParam function.

§Safety

To create a dialog, you must provide a dialog procedure.

source

unsafe fn DialogBoxIndirectParam( &self, dialog_template: &DLGTEMPLATE, hwnd_parent: Option<&HWND>, dialog_proc: DLGPROC, init_param: Option<isize> ) -> SysResult<isize>

DialogBoxIndirectParam function.

§Safety

To create a dialog, you must provide a dialog procedure.

source

unsafe fn DialogBoxParam( &self, resource_id: IdStr, hwnd_parent: Option<&HWND>, dialog_proc: DLGPROC, init_param: Option<isize> ) -> SysResult<isize>

DialogBoxParam function.

§Safety

To create a dialog, you must provide a dialog procedure.

source

fn GetClassInfoEx( &self, class_name: &str, wcx: &mut WNDCLASSEX<'_> ) -> SysResult<ATOM>

GetClassInfoEx function.

§Examples

Retrieving information of a window class created in our application:

use winsafe::{self as w, prelude::*};

let mut wcx = w::WNDCLASSEX::default();
w::HINSTANCE::GetModuleHandle(None)?
    .GetClassInfoEx("SOME_CLASS_NAME", &mut wcx)?;
source

fn LoadAccelerators(&self, table_name: IdStr) -> SysResult<HACCEL>

LoadAccelerators function.

source

fn LoadCursor(&self, resource_id: IdIdcStr) -> SysResult<DestroyCursorGuard>

LoadCursor function.

§Examples

Loading a system cursor:

use winsafe::{self as w, prelude::*, co};

let sys_cursor = w::HINSTANCE::NULL
    .LoadCursor(w::IdIdcStr::Idc(co::IDC::ARROW))?;
source

fn LoadIcon(&self, icon_id: IdIdiStr) -> SysResult<DestroyIconGuard>

LoadIcon function.

§Examples

Loading a system icon:

use winsafe::{self as w, prelude::*, co};

let sys_icon = w::HINSTANCE::NULL
    .LoadIcon(w::IdIdiStr::Idi(co::IDI::INFORMATION))?;
source

fn LoadMenu(&self, resource_id: IdStr) -> SysResult<HMENU>

LoadMenu function.

source

fn LoadString(&self, id: u16) -> SysResult<String>
