932 Appendix A: System Routines - Operating System handleRclKey Declaration: void handleRclKey (BOOL ReplaceCRs) Category(ies): Operating System, Keyboard, Variables Description: Manages the dialog box which appears when 2 £ is pressed. A pop-up dialog box is displayed requesting the name of a variable. The contents of the variable are converted to text and pasted to the current application. Inputs: ReplaceCRs - If TRUE, carriage returns are converted to colons after the contents of the variable have been converted to text. The variable itself is not changed. If FALSE, carriage returns remain unchanged. Outputs: None Assumptions: The current application receives a CM_PASTE_HANDLE command. It is the responsibility of the application to make sure the handle contents are pasted to a text field or to call the default event handler for this message if the app has no active text field. Nothing is pasted if the user pressed N to cancel the 2 £ dialog. Side Effects: May cause heap compression. May throw errors. Availability: All versions of the TI-89 / TI-92 Plus. TI-89 / TI-92 Plus Differences: None See Also: Not applicable. Example: case CM_RCL: if (! (te->flags & TE_READ_ONLY)) handleRclKey(FALSE); break; /* User pressed [RCL] */ /* Is my text field writeable? */ /* Yes, allow variable recall */ /* No, ignore [RCL] key */ TI-89 / TI-92 Plus Developer Guide Not for Distribution Beta Version January 26, 2001
