Caveats and Recommendations when Creating Custom Controls and Indicators

The following list describes some of the caveats and recommendations to consider when you create custom controls and indicators:

• Graphics you create on one platform look slightly different when you load them on another platform. For example, a graphic with an irregular shape on a transparent background might have a solid white background on another platform.
• Customizing a control or indicator in the Control Editor window changes only the appearance of the control or indicator, not the behavior of the control or indicator. You cannot use the Control Editor window to change the way a control or indicator displays data. You also cannot use the Control Editor window to change the way a control or indicator behaves when you edit it, such as when you resize it. For example, when you make a ring control taller, the increment and decrement arrows also increase in height. If you move the increment and decrement arrows so they are side by side at the bottom of a ring control, the buttons become taller when the ring control becomes taller.
• If you experience irregular editing behavior using a custom control or indicator, use a strict type definition to correct this error.
• Controls and indicators may customize differently depending on the style of the control or indicator. For example, when you change the color of a modern style numeric control, the color of the increment and decrement buttons change as well. On a silver style numeric control, the color of the increment and decrement buttons do not change.
