# Loader
|
|
|
|
<link-summary>UI guidelines on using loaders.</link-summary>
|
|
|
|
<tldr>
|
|
|
|
**Implementation:** [`AnimatedIcon.Default`](%gh-ic%/platform/ide-core/src/com/intellij/ui/AnimatedIcon.java)
|
|
|
|
</tldr>
|
|
|
|
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.
|
|
<tabs group="languages">
|
|
<tab title="Kotlin" group-key="kotlin">
|
|
|
|
```kotlin
|
|
JLabel(
|
|
"Loading...",
|
|
AnimatedIcon.Default(),
|
|
SwingConstants.LEFT
|
|
)
|
|
```
|
|
|
|
</tab>
|
|
<tab title="Java" group-key="java">
|
|
|
|
```java
|
|
new JLabel(
|
|
"Loading...",
|
|
new AnimatedIcon.Default(),
|
|
SwingConstants.LEFT
|
|
);
|
|
```
|
|
|
|
</tab>
|
|
</tabs>
|
|
|
|
|
|
|
|
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.
|

## Placement
|
|
|
|
<table style="none">
|
|
|
|
<tr>
|
|
<td> Inside a field </td>
|
|
<td> <img src="placement_field.png" width="161"/> </td>
|
|
</tr>
|
|
|
|
<tr>
|
|
<td colspan="2">
|
|
<code-block lang="java">
|
|
ExpandableTextField textField = new ExpandableTextField();
|
|
textField.addExtension(
|
|
Extension.create(new AnimatedIcon.Default(), null, null)
|
|
);
|
|
</code-block>
|
|
</td>
|
|
</tr>
|
|
|
|
<tr>
|
|
<td>In a corner</td>
|
|
<td> <img src="placement_corner.png" width="32" />
|

|

</td>
