Example: Load "guilib.ring" New qapp { win1 = new qwidget() { setwindowtitle("Drawing using QPixMap") setgeometry(100,100,500,500) label1 = new qlabel(win1) { setgeometry(10,10,400,400) settext("") 145

- 9. Ring Documentation, Release 1.9 2. The Objects Library is updated to include the next functions • Last_WindowID() • Open_WindowNoShow() • Open_WindowAndLink() Also the class name (WindowViewBase) is changed to (WindowsViewParent). In The next code for example the Open_WindowAndLink() will create an object from the SecondWindowController Class Then will add the Method SecondWindow() to the FirstWindowController Class Also will add the Method FirstWindow() to the SecondWindowController Class So the SendMessage() method in FirstWindowController class can use the SecondWindow() method to access the object. class firstwindowController from windowsControllerParent oView = new firstwindowView func OpenSecondWindow Open_WindowAndLink(:SecondWindowController,self) 10.2. Better RingQt 147
- 10. Ring Documentation, Release 1.9 func SendMessage if IsSecondWindow() SecondWindow().setMessage("Message from the first window") ok func setMessage cMessage oView.Label1.setText(cMessage) 3. The next classes are added to RingQt • QPixMap2 • QScrollArea • QSplitter • QCompleter • QCompleter2 • QCompleter3 • QProcess • QMdiArea • QMdiSubWindow • QCursor • QListView • QDesktopServices 4. Many constants are defined in qt.rh (loaded by guilib.ring) 5. New Classes names - Index Start from 1 We added new classes to RingQt - another version of classes where the class names doesn’t start with the “q” letter Also updated methods so the index start from 1 when we deal with the GUI controls like • ComboBox • ListWidget • TableWidget • TreeWidget These classes are inside guilib.ring under the package name : System.GUI To use it load "guilib.ring" import System.GUI This doesn’t have any effect on our previous code, It’s just another choice for better code that is consistent with Ring rules. Also the form designer is updated to provide us the choice between using classes where (index start from 0) or (index start from 1) Example (Uses the Form Designer) 1. https://github.com/ring-lang/ring/blob/master/applications/formdesigner/tests/indexstart/indexstartView.ring 10.2.
