<lsl> // ********** SIMPLE DIALOG MODULE ********** // // By Nargus Asturias // Version 1.58 // // Support only one dialog at a time. DO NOT request multiple dialog at once! // Use of provided functions are recommented. Instruction here are for hardcore programmers only! // // Request: Send MessageLinked to the script. There are 3 dialog modes: // lnkDialog : Normal dialog with message and buttons // lnkDialogNumericAdjust : A dialog with buttons can be used to adjust numeric value // lnkDialogTextBox : A dialog with a text input field // lnkDialogNotify : Just a simple notification dialog. No return value and no buttons. // // Send MessageLinked with code lnkDialogReshow to force active dialog to reappear. // Send MessageLinked with code lnkDialogCancel to force cancel active dialog // // If a lnkDialog is requested with more than 12 buttons, multi-pages dialog is used to show the buttons. // // [ For lnkDialog ] // MessageLinked Format: // String part: List dumped into string, each entry seperated by '||' // Field 1: Dialog message (512 bytes maximum) // Field 2: Time-out data (integer) // Field 3-4: Button#1 and return value pair // Field 5-6: Button#2 and return value pair // And go on... // Key part: Key of AV who attend this dialog // // Response: MessageLinked to the prim that requested dialog (but no where else) // num == lnkDialogResponse: AV click on a button. The buttons value returned as a string // num == lnkDialogTimeOut: Dialog timeout. // // [ For lnkDialogNumericAdjust ] // MessageLinked Format: // String part: List dumped into string, each entry seperated by '||' // Field 1: Dialog message (512 bytes maximum) // Put {VALUE} where you want the current value to be displayed) // Field 2: Time-out data (integer) // Field 3: Most significant value (ie. 100, for +/-100) // Field 4: String-casted numeric value to be adjusted // Field 5: 2nd most significant value (ie. 10, for +/-10) // Field 6: Use '1' to enable "+/-" button, '0' otherwise. // Field 7: 3nd significant value (ie. 1, for +/-1) // Field 8: Use '1' for integer, or '0' for float // Field 9: Least significant value (ie. 0.1, for +/-0.1) // Field 10: Reserved. Not used. // Key part: Key of AV who attend this dialog // // Response: MessageLinked to the prim that requested dialog (but no where else) // num == lnkDialogResponse: OK or Cancel button is clicked. The final value returned as string. // num == lnkDialogTimeOut: Dialog timeout. // // ******************************************* //
