Overview

The Timer Web widget allows Mendix developers to integrate a customizable countdown timer into their applications. You can define the duration in minutes, reset the timer using a Boolean attribute, and trigger actions (nanoflows or microflows) when the timer completes or when clicked.

• 🎨 Customizable – Supports Mendix styling options for appearance.

Properties

General Tab

• Duration in Minutes:Bind an integer attribute. This defines the countdown duration of the timer in minutes.

• resetTimer:Bind a Boolean attribute.

  • When set to true, the timer resets.

  • Should be set back to false after reset to allow further resets.

• On click:Action performed when the timer or button is clicked. Supported actions:

  • Call a nanoflow

  • Call a microflow

  • Show a page

• Nanoflow:Choose the nanoflow to execute.

• Nanoflow Arguments:Pass an object (e.g., PIN) or other values to the nanoflow.

Example Use Case

1. PIN Verification Flow

   • Duration = Time_In_Minutes (5 minutes).

   • resetTimer = Boolean reset.

   • When the timer completes or button is clicked, nanoflow VerifyPIN is triggered with PIN object as input.

2. Session Timeout

   • Duration = 30.

   • resetTimer = Bound to a session reset attribute.

   • On timeout → Logout nanoflow executes.

Installation

1. Download the Timer Web widget from the Mendix Marketplace.

2. Place it inside a Data View or Layout Grid where you need countdown functionality.

3. Configure the properties as described.

Configuration Steps

1. Add an Integer attribute in your entity (e.g., Time_In_Minutes).

2. Add a Boolean attribute in your entity (e.g., reset).

3. Drop the Timer Web widget inside a Data View bound to the entity.

4. Configure:

   • Duration in Minutes → Time_In_Minutes.

   • resetTimer → reset.

   • On click → Select Nanoflow/Microflow.

   • Pass arguments if required (e.g., PIN object).

Limitations

• Only supports countdown in minutes (not seconds).

• Requires a data context (entity) for binding attributes.
