Automatic gtk::ListStore
struct derive for Rust.
In order to use this crate, you have to add the following dependencies into
your project's Cargo.toml
file:
[dependencies]
gtk_liststore_item = "1.2.0"
After the crate is installed, you can enjoy the ListStoreItem
derive!
By defining the following structure:
#[derive(ListStoreItem)]
struct Item {
name: String,
value: u32,
progress: u32,
is_cool: bool,
}
You can directly create and add items to the gtk::ListStore
model:
let mut list_store: gtk::ListStore = Item::new_liststore();
for i in 0..10 {
let item = Item {
name: format!("foobar{}", i),
value: rand::random(),
progress: rand::random::<u32>() % 100,
is_cool: rand::random(),
};
item.insert_into_liststore(&mut list_store);
}
And directly see the result inside a GtkTreeView
widget:
Without this crate, you would have to manually serialize each of the entries in your struct with their type and position:
fn new_liststore() -> gtk::ListStore {
gtk::ListStore::new(&[
String::static_type(),
u32::static_type(),
u32::static_type(),
bool::static_type(),
])
}
fn get_item(liststore: >k::ListStore, iter: >k::TreeIter) -> Item {
Some(Item {
name: list_store.value(&iter, 0).get::<String>().ok()?,
value: list_store.value(&iter, 1).get::<u32>().ok()?,
progress: list_store.value(&iter, 2).get::<u32>().ok()?,
is_cool: list_store.value(&iter, 3).get::<bool>().ok()?,
})
}
fn insert_item(item: &Item, list_store: &mut gtk::ListStore) -> gtk::TreeIter {
list_store.insert_with_values(
None,
&[
(0, &self.name),
(1, &self.value),
(2, &self.progress),
(3, &self.is_cool)
]
)
}
This can become pretty tedious, hence this crate to ease the process.
