Another navigation strategy in Ignition is to have Forward and Back Buttons on your main screen to navigate between different windows. This strategy is perfect for a small business process with ordered steps. It does not have a docked window, tree view, or tabs to navigate around. It is one big main window and has buttons to navigate forward and back from one Main Window to the next in the list.

Setting Up the Back and Forward Buttons

This navigation strategy is very simple to setup in the Designer. You can start by creating your project using a blank template.  

  1. In the Project Browser, right click on the Main Windows folder and create a new Main Window. You have the option of renaming your Main Window to whatever best describes your window, or keeping the default name, (i.e., Main Window 1). Add a label to the window for clarity (i.e., Main Window 1) so when you navigate through different windows, you know precisely what window you're viewing. Repeat this step to create Main Window 2 and Main Window 3.

  2. From the Component Palette in Designer, drag a Button component to your Main Window 1. Label the button, Main Window 2.  
    1. Add a right green arrow to your button component. With the Button component selected, click the folder to the right of the Image Path property to open the Image Management tool. Open the Builtin icons folder to find a right green arrow. Once you have the arrow on your button, move it to the right side of the button by setting the Horizontal Text Position property to Left in the Property Editor. 
  3. Now you need to tell the Main Window 2 button what to do when someone clicks on it. Right click on the Main Window 2 button, select Scripting, and the component scripting dialogue box will open. 

  4. Under the Event Handlers, open the action folder and select actionPerformed
    1. Click the Open / Swap and Swap radio buttons. The Swapping function is used to put buttons on windows for easily building simple scripts to go back and forth between different main windows. The Swap function ensures only one main window will be open at a time. 
    2. From the Window dropdown box, select Main Windows/Main Window 2.  Click OK.

  5. Save and Publish your project.
  6. Open your Client.  Click on the Main Window 2 button and Main Window 1 will be swapped out with Main Window 2.

  7. Repeat Steps 2 and 3 to create Main Windows 2 and 3, respectively. On Main Window 2 make sure you have a button for both Main Window 1 and Main Window 3. Set your window path for the Main Window 1 button to Main Windows/Main Window 1 (refer to step 4). For the Main Window 3 button, set the window path to Main Windows/Main Window 3.  

  8. In the following example, Main Window 2 is open. By clicking either button, it will navigate you to the respective window. Click on the Main Window 1 button, and Main Window 2 swaps out and opens Main Window 1. Click on the Main Window 3, and Main Window 2 swaps out and opens with Main Window 3. You'll notice that you always have one main window open.
