Struct ImageList 

pub struct ImageList { /* private fields */ }

Represents a wxImageList.

This struct is a wrapper around the wxWidgets ImageList object. It provides owned and unowned variants - owned instances are destroyed on Drop, while unowned instances (obtained from controls) are managed by wxWidgets.

Implementations

impl ImageList

pub fn new(width: i32, height: i32, mask: bool, initial_count: i32) -> Self

Creates a new, empty image list.

Arguments

• width - The width of images in the list.
• height - The height of images in the list.
• mask - true to use a mask, false otherwise.
• initial_count - The initial number of images the list can store (can be resized).

Returns ImageList on success. Panics if creation failed.

pub fn as_ptr(&self) -> *mut wxd_ImageList_t

Returns the raw pointer to the underlying wxImageList object.

This pointer can be used for FFI calls. The caller must ensure the ImageList object (and thus the pointer) remains valid.

pub fn add_bitmap(&self, bitmap: &Bitmap) -> i32

Adds a bitmap to the image list. The wxImageList makes an internal copy of the bitmap.

Arguments

• bitmap - The bitmap to add.

Returns the index of the added image, or -1 if an error occurred.

pub fn add_bitmap_with_mask(&self, bitmap: &Bitmap, mask: &Bitmap) -> i32

Adds a bitmap and its mask to the image list. The wxImageList makes internal copies of both the bitmap and the mask.

Arguments

• bitmap - The bitmap to add.
• mask - The mask for the bitmap.

Returns the index of the added image, or -1 if an error occurred.

pub fn get_image_count(&self) -> i32

Returns the number of images in the list.

pub fn remove_all(&self) -> bool

Removes all images from the list.

Returns true if successful, false otherwise (e.g., if the list pointer is null).

Trait Implementations

impl Debug for ImageList

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Drop for ImageList

fn drop(&mut self)

Executes the destructor for this type.

fn pin_drop(self: Pin<&mut Self>)

🔬This is a nightly-only experimental API. (pin_ergonomics)

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.
