# AddNextClickAction

## Introduction

AddNextClickAction adds a delegate to be raised the next time the Cursor performs a primary click. This call is not bound to a particular control, and it can be used to handle the user clicks off of the control. This method is used internally to close Menus and ComboBoxes, but it can be used to close custom popups, modals, and context menus.

## Code Example

The following code creates a Button which displays a StackPanel of Buttons. The StackPanel closes on any click, whether on the StackPanel or not, but each button in the StackPanel registers a click.

```csharp
// Initialize
var popupPanel = new StackPanel();
popupPanel.IsVisible = false;
popupPanel.Anchor(Anchor.Center);
Gum.ModalRoot.AddChild(popupPanel);
for(int i = 0; i < 5; i++)
{
    var innerButton = new Button();
    popupPanel.AddChild(innerButton);
    innerButton.Text = "Button " + i;
    innerButton.Click += (_,_) =>
    {
        System.Diagnostics.Debug.WriteLine("Clicked " + innerButton.Text); 
    };
}

var button = new Button();
button.AddToRoot();
button.Anchor(Anchor.Center);
button.Text = "Click me to show popup";
button.Y = -200;
button.Click += (not, used) =>
{
    popupPanel.IsVisible = true;
    InteractiveGue.AddNextClickAction(() =>
    {
        popupPanel.IsVisible = false;
    });
};

```

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.flatredball.com/gum/code/gum-code-reference/interactivegue/addnextclickaction.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
