#### Methods (METHOD)

1. **`New( oWnd, nBtnWidth, nBtnHeight, aPrompts, acBitmaps, nOption, l3D, l2007 )`**
- **Type:** Constructor
- **Description:** This method initializes a new instance of the `TBarTabs` class. It sets up the tab control, creates the bars, and configures the initial state of the tabbed interface.
- **Parameters:**
- `oWnd`: The parent window object.
- `nBtnWidth`: The width of the buttons (tabs).
- `nBtnHeight`: The height of the buttons (tabs).
- `aPrompts`: An array of strings representing the labels for each tab.
- `acBitmaps`: An array of bitmaps associated with each tab (optional).
- `nOption`: The index of the initially selected tab (default is 1).
- `l3D`: A logical value indicating whether to use 3D effects for the bars (default is `.f.`).
- `l2007`: A logical value indicating whether to use a 2007-style appearance (default is `.t.`).

2. **`AddBar( cPrompt, cBitmap )`**
- **Type:** Public
- **Description:** This method adds a new bar (or tab) to the tabbed interface. It creates a new `TBar` object, adds it to the `aBars` array, and updates the tab control with the new tab.
- **Parameters:**
- `cPrompt`: The label for the new tab.
- `cBitmap`: The bitmap associated with the new tab (optional).
- **Returns:** The newly created `TBar` object.

3. **`SetBar( nOption )`**
- **Type:** Protected
- **Description:** This method is used internally to switch between different bars (or tabs). It hides the currently visible bar and shows the bar corresponding to the selected tab.
- **Parameters:**
- `nOption`: The index of the bar to be displayed.
- **Returns:** The index of the previously active bar.

#### Detailed Method Descriptions

- **`New` Method:**
- The `New` method initializes the `TBarTabs` object. It sets up the panel, creates the tab control, and initializes the bars. The method also sets the initial active bar based on the `nOption` parameter. The bars are created with the specified dimensions and styles, and the initially selected bar is displayed while the others are hidden.

- **`AddBar` Method:**
- The `AddBar` method allows dynamic addition of new bars (or tabs) to the tabbed interface. It adds a new tab to the `oTabs` object and creates a corresponding `TBar` object, which is then added to the `aBars` array. The new bar is initially hidden, and the method ensures that the currently active bar remains visible.

- **`SetBar` Method:**
- The `SetBar` method is responsible for switching between bars. It hides the currently visible bar and shows the bar corresponding to the selected tab. This method is called internally when a tab is selected, ensuring that the correct bar is displayed.

#### Usage Example
```xBase
// Assuming oWnd is a valid window object
LOCAL oBarTabs := TBarTabs():New( oWnd, 100, 30, { "Tab1", "Tab2", "Tab3" }, { "bmp1.bmp", "bmp2.bmp", "bmp3.bmp" } )

// Adding a new tab dynamically
oBarTabs:AddBar( "Tab4", "bmp4.bmp" )

// Switching to the second tab
oBarTabs:SetBar( 2 )
```

This class is particularly useful in applications where you need to manage multiple views or panels within a single window, allowing users to switch between them using a tabbed interface.

FWH Class TBlock documentation:

### Class Documentation: `TBlock`

#### Overview:
The `TBlock` class is a part of the FiveWin framework, which is commonly used in Clipper and xBase programming. This class is designed to encapsulate a code block (a piece of code that can be executed later) and provides methods to evaluate or execute this code block with optional parameters.

#### Purpose:
The `TBlock` class allows you to store a code expression as a string, convert it into an executable code block, and then evaluate or execute this block with up to five parameters. This is useful in scenarios where you need to dynamically execute code based on runtime conditions or configurations.

---

### DATA Members:

1. **`cExpression`**
- **Type:** String
- **Description:** This data member stores the code expression as a string. The expression is later converted into an executable code block.

2. **`bBlock`**
- **Type:** Code Block
- **Description:** This data member holds the executable code block that is created from the `cExpression` string. It is used to evaluate or execute the code.

---

### METHODS:

1. **`New( cExpression )`**
- **Type:** Constructor
- **Description:** This method initializes a new instance of the `TBlock` class. It takes a string `cExpression` as input, which represents the code to be executed. The method checks if the expression is valid. If valid, it converts the string into an executable code block and assigns it to `::bBlock`. If the expression is invalid, it displays an alert message.
- **Parameters:**
- `cExpression`: A string representing the code expression to be executed.
- **Returns:** `nil` (no return value).

2. **`Eval( uPar1, uPar2, uPar3, uPar4, uPar5 )`**
- **Type:** Inline Method
- **Description:** This method evaluates the code block stored in `::bBlock` with up to five optional parameters. If `::bBlock` is not `nil`, it executes the code block using the `Eval` function and passes the parameters to it. If `::bBlock` is `nil`, it does nothing.
- **Parameters:**
- `uPar1`, `uPar2`, `uPar3`, `uPar4`, `uPar5`: Optional parameters to be passed to the code block.
- **Returns:** The result of evaluating the code block, or `nil` if `::bBlock` is `nil`.

3. **`Exec( uPar1, uPar2, uPar3, uPar4, uPar5 )`**
- **Type:** Inline Method
- **Description:** This method is functionally identical to `Eval`. It evaluates the code block stored in `::bBlock` with up to five optional parameters. If `::bBlock` is not `nil`, it executes the code block using the `Eval` function and passes the parameters to it. If `::bBlock` is `nil`, it does nothing.
- **Parameters:**
- `uPar1`, `uPar2`, `uPar3`, `uPar4`, `uPar5`: Optional parameters to be passed to the code block.
- **Returns:** The result of evaluating the code block, or `nil` if `::bBlock` is `nil`.

---

### Example Usage:

```clipper
// Create a new TBlock instance with a code expression
oBlock := TBlock:New( "{ |x, y| x + y }" )

// Evaluate the code block with parameters
? oBlock:Eval( 5, 10 ) // Output: 15

// Execute the code block with parameters
? oBlock:Exec( 3, 7 ) // Output: 10
```

---

### Notes:
- The `Eval` and `Exec` methods are identical in functionality. The presence of both methods might be for backward compatibility or to provide alternative naming conventions.
- The `New` constructor ensures that the provided expression is valid before converting it into a code block. If the expression is invalid, it alerts the user and does not initialize the code block.
- The `&` operator in the `New` method is used to convert the string expression into a code block. This is a powerful feature but should be used with caution to avoid security risks (e.g., code injection).

This class is a simple yet powerful tool for dynamically executing code in FiveWin applications.

- The method returns the instance of the `TBrushEx` class.

#### 3. **`End()`**
- **Type**: Destructor
- **Description**:
- This method is used to clean up resources by deleting the brush (`hBrush`) and the bitmap (`hBitmap`) using the `DeleteObject` function.
- It is marked as `INLINE`, meaning the code is directly inserted where the method is called, improving performance for small, frequently used methods.

---

### Notes:
- The `TBrushEx` class is useful for creating custom brushes with gradients or flat colors, which can be used in graphical applications.
- The user must manually call the `End()` method to release resources when the brush is no longer needed, unless the system manages it.
- The commented-out lines (`//::nCount := 1` and `//AAdd( ::aBrushes, Self )`) suggest that the class might have been designed to track instances or manage a collection of brushes, but this functionality is not implemented in the provided code.

---

This class is a powerful tool for creating and managing custom brushes in graphical applications, especially when gradients or specific color patterns are required.

---

### **METHODS**

1. **`New( cKey )`**
- **Purpose**: Constructor method to initialize the `TChatgpt` object.
- **Parameters**:
- `cKey`: The API key for authenticating with the OpenAI API.
- **Description**: Initializes the `cKey` and sets up a new libcurl session using `curl_easy_init()`.
- **Returns**: The initialized object (`Self`).

2. **`Send()`**
- **Purpose**: Sends a prompt to the OpenAI API and retrieves the response.
- **Description**:
- Configures the libcurl session with the necessary options (e.g., URL, headers, POST data).
- Constructs a JSON payload containing the model and prompt.
- Executes the request using `curl_easy_perform()`.
- Captures the HTTP response code and the raw JSON response.
- **Returns**: The raw JSON response (`::cResponse`).

3. **`Reset()`**
- **Purpose**: Resets the libcurl session and clears the response data.
- **Description**:

5. **`GetValue()`**
- **Purpose**: Extracts specific values from the JSON response.
- **Description**:
- Decodes the JSON response into a Harbour hash.
- Iterates through the provided keys to extract nested values.
- Handles errors gracefully using a `TRY...CATCH` block.
- **Returns**: The extracted value from the JSON response.

---

### **Usage Example**

```harbour
// Initialize the TChatgpt object with your API key
oChat := TChatgpt():New( "your-api-key-here" )

// Set the prompt
oChat:cPrompt := "What is the capital of France?"

// Send the request and get the response
cResponse := oChat:Send()

// Extract a specific value from the response
cCapital := oChat:GetValue( "choices", "message", "content" )

// Display the result
? "The capital of France is:", cCapital

// Clean up resources
oChat:End()
```

---

### **Notes**
- The class assumes the use of the `hbcurl` library for HTTP requests. Ensure the library is properly installed and configured.
- The `GetValue` method is designed to handle nested JSON structures, but it may require adjustments based on the specific structure of the API response.
- Error handling is minimal in this implementation. Consider extending it to handle specific HTTP or libcurl errors more robustly.

This class provides a simple and reusable interface for interacting with the OpenAI ChatGPT API in Harbour applications.
