Sample Application

CalcKeyboard is a popup keyboard extension for Satellite Forms, similar to the PalmOS built in alpha, numeric, and international keyboards, that implements a basic four-function calculator. When invoked, CalcKeyboard pops up overtop of your current form, and displays the numeric value of the active field as its starting value. The user can make the desired calculations by tapping on the CalcKeyboard keypad, and can choose to write the result back into the active field when the calculator is dismissed.

CalcKeyboard is simple, and completely intuitive for the end user. It even has a Tips/Info dialog available, like the standard Palm keyboards. For the SatForms developer, CalcKeyboard offers several customization features so you can tailor it to your application's needs. You can:

• set the title of the calculator
• set the caption of the Paste checkbox
• set the caption of the Done button
• set the caption of the Clear button
• hide the Paste option altogether
• hide the Tips/Info dialog
• set the number of decimal places to display
• set the escape prevention behaviour

In addition, CalcKeyboard automatically recognizes and uses the decimal character as specified in the Palm preferences.

CalcKeyboard is invoked by a script command, and the sample application demonstrates how to easily pop it up when the user taps on the Calculator silkscreen icon.
