# Dialog API

The Dialog API provides standardized dialogs that work consistently across desktop and web environments. Extension authors will find the prompt and confirm methods most useful.

## Basic Usage

### Prompt Dialog

```javascript  theme={null}
// Show a prompt dialog
app.extensionManager.dialog.prompt({
  title: "User Input",
  message: "Please enter your name:",
  defaultValue: "User"
}).then(result => {
  if (result !== null) {
    console.log(`Input: ${result}`);
  }
});
```

### Confirm Dialog

```javascript  theme={null}
// Show a confirmation dialog
app.extensionManager.dialog.confirm({
  title: "Confirm Action",
  message: "Are you sure you want to continue?",
  type: "default"
}).then(result => {
  console.log(result ? "User confirmed" : "User cancelled");
});
```

## API Reference

### Prompt

```javascript  theme={null}
app.extensionManager.dialog.prompt({
  title: string,             // Dialog title
  message: string,           // Message/question to display
  defaultValue?: string      // Initial value in the input field (optional)
}).then((result: string | null) => {
  // result is the entered text, or null if cancelled
});
```

### Confirm

```javascript  theme={null}
app.extensionManager.dialog.confirm({
  title: string,             // Dialog title
  message: string,           // Message to display
  type?: "default" | "overwrite" | "delete" | "dirtyClose" | "reinstall", // Dialog type (optional)
  itemList?: string[],       // List of items to display (optional)
  hint?: string              // Hint text to display (optional)
}).then((result: boolean | null) => {
  // result is true if confirmed, false if denied, null if cancelled
});
```
