How to use

Modal Dialog management.

This library provides basic modal dialog managements on Unity-GUI. Modal dialog box works like a function which gets input argument, does work, and returns return value. When a modal dialog box shows, input of other windows under showing dialog box will be blocked.

// show up TestDialogBox with an arugment
var handle = UiManager.Instance.ShowModalRoot<TestDialogBox>("Input your name?");
// waits for dialog to finish it's work
yield return StartCoroutine(handle.WaitForHide());
// gets return value from dialog
Debug.Log(handle.ReturnValue);

Define modal dialog box

DialogBox should inherit UiDialog. When dialog box shows up, OnShow handler will be invoked with param is passed by ShowModalRoot. When work done and there is a return value, Hide method can be used.

//
public class TestDialogBox : UiDialog
{
    public override void OnShow(object param)
    {
        // gets an argument from caller
        Message.text = (string)param;
        Input.text = "";
    }

    public void OnOkButtonClick()
    {
        // returns values to caller
        Hide(Input.text);
    }
}

Show modal dialog

It's quite simple to show modal dialog boxes but there are several ways for showing dialog box.

ShowModalPrefab: Use the prefab dialog box. Whenever show up new dialog, dialog box will be instantiated.
ShowModalTemplate: Use the template dialog box in the scene. Whenever show up new dialog, dialog box will be cloned.
ShowModal<T>: Use a passed dialog box whose type is T.
ShowModalRoot<T>: Use a named dialog box under Canvas/DialogBox in the scene.

For getting return value of it, there are two ways.

First one is using Hidden callback.

var handle = UiManager.Instance.ShowModalRoot<TestDialogBox>("Input your name?");
handle.Hidden += (dlg, val) => { Debug,Log(val); };

Second one is using coroutine. It's quite useful under modal chaining.

var handle = UiManager.Instance.ShowModalRoot<TestDialogBox>("Input your name?");
yield return StartCoroutine(handle.WaitForHide());
Debug.Log(handle.ReturnValue);

Common dialog boxes.

Common message box

UiMessageBox.Show("This is a message question <b>box</b>",
                  UiMessageBox.QuestionType.OkCancel,
                  r => { /* Callback */ });

Common input box

UiInputBox.Show("Please input your name:",
                "Input",
                r => { /* Callback */ });
