Rx Calculator

Description:
The TRxCalcEdit takes the display and editing of numeric data one step further: it provides a popup calculator to help you calculate the number. When you perform a calculation on the calculator, the result is inserted into the number edit’s display.

TRxCalcEdit have the keyboard restrictions, so the user cannot enter invalid characters. When the user leaves the field, the number is reformatted to display appropriately, accordingly with the DisplayFormat property.

The field value is stored in a write Value property so you should read and write to that in your program.

This field is of type Extended. You can also read and write Value as integer number using AsInteger property.

If the Glyph is set to a new bitmap, the gkCustom type is automatically set.
