# Loader
UI guidelines on using loaders.
**Implementation:** [`AnimatedIcon.Default`](%gh-ic%/platform/ide-core/src/com/intellij/ui/AnimatedIcon.java)
A loader informs users about performing a lengthy operation.
{width=330}
## When to use
Follow the rules for [progress indicators](progress_indicators.md).
## How to use
The loader form and sizes are the same in all themes. Use the default 16x16 loader in all cases.
```kotlin
JLabel(
"Loading...",
AnimatedIcon.Default(),
SwingConstants.LEFT
)
```
```java
new JLabel(
"Loading...",
new AnimatedIcon.Default(),
SwingConstants.LEFT
);
```
A loader may have a label if the process is long and the loader is shown in an empty area. In this case, use a [progress text](progress_text.md) as the label:
{width=597}
Remove the loader as soon as the process completes.
