If you already have an existing project, ViSi Genie might be the best for you.

This allows you to design a user interface and control it using your main/host controller without the need to program the display.

However, keep in mind that ViSi Genie have some limitations since it was designed to follow the most common behavior expected for each widget.

If you want or need a custom behavior, you can add custom code with ViSi Genie Magic which is available for the PRO version of the IDE. Keep in mind that you need a good understanding of program flow and 4DGL to efficiently utilize ViSi Genie Magic.

If you need full control of the display, you can use Designer or ViSi.

4D Graphics processors does not support transparency.

However, using Workshp4, you can add transparent images on your user interface using widgets like UserImages. Workshop4 will build these images on top of the background color or image used in the Form. This allows the image to still appear transparent in the actual application.

Workshop4 works fine in Windows 10.

This message is likely due to you having an old version of the IDE and upgrading to Windows 10 or after a Windows 10 update.

You can fix this manually by performing these procedures:

• Open Registry Editor
• Navigate to HKEY_CURRENT_USER\SOFTWARE\4DLabs\Workshop
• Delete the entire Workshop folder/key
• Reinstall Workshop4 using the latest installer

If you are using any of the following programming adaptors:

• uUSB-PA5-II
• gen4-PA
• 4D-UPA

This is caused by an issue with the Windows 10 driver of the USB-to-UART chip. This can easily be solved by using the Windows 7/8/8.1 driver that you can find here.

If you are using older 4D programming adaptors, this forum thread might help.

When using ViSi Genie or Serial (SPE) and turning the display into a slave device / secondary device, the host controller requires to have:

• 1 UART peripheral – provides ViSi Genie and Serial (SPE) communication between the host and the display
• 1 digital output pin – controls the reset pin of the display module

Keep in mind that the display pins are 3.3V with most of the pins being 5V tolerant. Please refer to the datasheets for more information.

It is recommended to use the Zip Project option when sharing projects to another person.

This ensures that all files required by the project is included when you send it.

This option can be accessed by going to File -> Zip Project while the project is opened and active in Workshop4.

Workshop4 is a Windows-only product. It is compatible with Windows XP to Windows 10 (Windows 7 or higher is recommended). Note that some older OS such as Windows ME and Vista has not been tested for some time due to availability, however, should still work.

It is possible to run Workshop4 under a virtual machine on Linux or Mac, however, it is not officially supported. It is up to the user to set this up. Many customers have had success running Workshop4 under a VM, but is not something we can support officially.

Please make sure that there are no spaces before and after the characters.

Note: Common licensing errors can be solved by simply running the latest version of Workshop4. If you are running into any issues, please try updating your Workshop4 to the latest version.

No, it doesn’t. 4DGL only supports 16-bit variables. However, by utilizing a 2-element array which results in a 32-bit space, some processors can support 32-bit floats. These processors utilize internal functions to store floating-point values and perform operations.
