- 3. Ring Documentation, Release 1.9 8.4 Calculator Application The Calculator application is added to the Applications folder. Screen Shot: 8.5 Better Ring Notepad 1. Ring Notepad is updated to include some new styles and the Main File ToolBar The idea of the Main File ToolBar is to determine the main file in the project When the project contains many source code files This way you can run the project ( Main File ) at any time while opening other files in the project without the need to switch to the Main File to run the project. To quickly use this feature (Open the project main file) Press Ctrl+Shift+M to set the current source code file as the main file Open and modify other source code files in the project To run the project (Main File) at any time press Ctrl+Shift+F5 (GUI) or Ctrl+Shift+D (Console) Screen Shots: 8.4. Calculator Application 91

- 5. Ring Documentation, Release 1.9 2. The output window is updated to display the new lines correctly and contains the “Clear” button. Screen Shot: (3) The Ring Notepad is updated to quickly open and switch between large files while preparing the functions/classes lists in the background. Screen Shot: 8.5. Better Ring Notepad 93
- 6. Ring Documentation, Release 1.9 8.6 Better StdLib New Functions • Print2Str() • ListAllFiles() • SystemCmd() 1. The Print2Str() is a new function added to the StdLib Example: load "stdlib.ring" world = "World!" mystring = print2str("Hello, #{world} nIn Year n#{2000+17} n") see mystring + nl Output: Hello, World! In Year 2017 2. The ListAllFiles() is a new function added to the StdLib Using this function we can quickly do a process on a group of files in a folder and it’s sub folders. Example: load "stdlib.ring" aList = ListAllFiles("c:/ring/ringlibs","ring") # *.ring only 8.6. Better StdLib 94
- 7. Ring Documentation, Release 1.9 aList = sort(aList) see aList Example: load "stdlib.ring" see listallfiles("b:/ring/ringlibs/weblib","") # All Files 3. The SystemCmd() is a new function added to the StdLib The function will execute a system command like the System() function but will return the output in a string. Example: cYou = SystemCmd("whoami") See "SystemCmd: whoami ====="+ nl + cYou +nl Output: SystemCmd: whoami ===== desktop-umbertoumberto 8.7 Better WebLib The WebLib is updated to include the HTMLPage class Using this class we can create HTML documents without printing the output to the standard output So instead of using the WebLib in Web Applications only We can use it in Console/GUI/Mobile Applications too Example: load "stdlib.ring" load "weblib.ring" import System.Web func main mypage = new HtmlPage { h1 { text("Customers Report") } Table { style = stylewidth("100%") + stylegradient(4) TR { TD { WIDTH="10%" text("Customers Count : " ) } TD { text (100) } } } Table { style = stylewidth("100%") + stylegradient(26) TR { style = stylewidth("100%") + stylegradient(24) 8.7. Better WebLib 95
- 8. Ring Documentation, Release 1.9 TD { text("Name " ) } TD { text("Age" ) } TD { text("Country" ) } TD { text("Job" ) } TD { text("Company" ) } } for x = 1 to 100 TR { TD { text("Test" ) } TD { text("30" ) } TD { text("Egypt" ) } TD { text("Sales" ) } TD { text("Future" ) } } next } } write("report.html",mypage.output()) Using this feature we can create reports quickly using WebLib & GUILib together Example: load "stdlib.ring" load "weblib.ring" load "guilib.ring" import System.Web import System.GUI new qApp { open_window(:CustomersReportController) exec() } class CustomersReportController oView = new CustomersReportView func Start CreateReport() func CreateReport mypage = new HtmlPage { h1 { text("Customers Report") } Table { style = stylewidth("100%") + stylegradient(4) TR { TD { WIDTH="10%" text("Customers Count : " ) } TD { text (100) } } } Table 8.7. Better WebLib 96
- 9. Ring Documentation, Release 1.9 { style = stylewidth("100%") + stylegradient(26) TR { style = stylewidth("100%") + stylegradient(24) TD { text("Name " ) } TD { text("Age" ) } TD { text("Country" ) } TD { text("Job" ) } TD { text("Company" ) } } for x = 1 to 100 TR { TD { text("Test" ) } TD { text("30" ) } TD { text("Egypt" ) } TD { text("Sales" ) } TD { text("Future" ) } } next } } write("report.html",mypage.output()) func PrintEvent printer1 = new qPrinter(0) { setoutputformat(1) setoutputfilename("report.pdf") } oView { web.print(printer1) web.show() } system ("report.pdf") class CustomersReportView win = new window() { setwindowtitle("Report Window") setgeometry(100,100,500,500) web = new webview(win) { setgeometry(100,100,1000,500) loadpage(new qurl("file:///"+ currentdir()+"/report.html")) } new pushbutton(win) { setGeometry(100,20,100,30) settext("Print") setclickevent(Method(:PrintEvent)) } showMaximized() } Screen Shot: 8.7. Better WebLib 97
- 10. Ring Documentation, Release 1.9 8.8 Better RingQt New classes added to RingQt : • QStringRef • QMutex • QMutexLocker • QBuffer • QBluetoothAddress • QBluetoothDeviceDiscoveryAgent • QBluetoothDeviceInfo • QBluetoothHostInfo • QBluetoothLocalDevice • QBluetoothServer • QBluetoothServiceDiscoveryAgent • QBluetoothServiceInfo • QBluetoothSocket • QBluetoothTransferManager • QBluetoothTransferReply • QBluetoothTransferRequest • QBluetoothUuid 8.8.
