TrackBar: Bad encoding of TrackBar's text
Last modified: 2010-08-31 14:19:41 UTC
PROBLEM STATEMENT: when you get the text from a trackbar, the encoding of text is bad. REPRODUCE: 1. start uia2atk/test/samples/trackbar.py and accercier 2. navigate to a track bar(slider) from left side 3. open IPython tab 4. try to issue "acc.queryText().getText(0, acc.queryText().characterCount)" RESULTS: the output is '\xe2\x80\x8e1' EXPECTED RESULTS: the output should be 1

Oops, I just logged a duplicate of this bug. Here is my PROBLEM STATEMENT, maybe it will provide some extra information: I am a bit confused, but it looks like I am getting a UTF-8 value back from the text interface of a TrackBar's "slider" accessible. The value I expect is "1". I am getting back a "1" in a string, but it appears to be prefixed with some UTF-8 bytes. The value I am getting is '\xe2\x80\x8e1', that is, a "1" prefixed with "\xe2\x80\x8e". Obviously, my test fails because '1' != '\xe2\x80\x8e1'. "\xe2\x80\x8e" alone (without the "1", appears to be a blank space or something).
Fixed; waiting for review (#343)
Fixed in UiaAtkBridge R153482.
Hi Mike, I try to verify this bug, but after I installed uiaatkbridge with r153482 package, I get this error. no implementation for interface method Atk.TableImplementor::GetSelectedColumns(int&) in class UiaAtkBridge.Table METHOD .ctor(System.Windows.Automation.Provider.IRawElementProviderFragment) METHOD RaiseAutomationEvent(System.Windows.Automation.AutomationEvent,System.Windows.Automation.AutomationEventArgs) METHOD RaiseStructureChangedEvent(object,System.Windows.Automation.StructureChangedEventArgs) METHOD RaiseAutomationPropertyChangedEvent(System.Windows.Automation.AutomationPropertyChangedEventArgs) METHOD RefAt(int,int) METHOD GetIndexAt(int,int) METHOD GetColumnAtIndex(int) METHOD GetRowAtIndex(int) METHOD get_NColumns() METHOD get_NRows() METHOD GetColumnExtentAt(int,int) METHOD GetRowExtentAt(int,int) METHOD get_Caption() METHOD set_Caption(Atk.Object) METHOD GetColumnDescription(int) METHOD GetColumnHeader(int) METHOD GetRowDescription(int) METHOD GetRowHeader(int) METHOD get_Summary() METHOD set_Summary(Atk.Object) METHOD SetColumnDescription(int,string) METHOD SetColumnHeader(int,Atk.Object) METHOD SetRowDescription(int,string) METHOD SetRowHeader(int,Atk.Object) METHOD get_SelectedColumns() METHOD get_SelectedRows() METHOD GetSelectedColumns(int&) METHOD GetSelectedColumns(int[]&) METHOD GetSelectedRows(int&) METHOD GetSelectedRows(int[]&) METHOD IsColumnSelected(int) METHOD IsRowSelected(int) METHOD IsSelected(int,int) METHOD AddRowSelection(int) METHOD RemoveRowSelection(int) METHOD AddColumnSelection(int) METHOD RemoveColumnSelection(int) METHOD EmitRowReorderingSignal() METHOD OnRefStateSet() Error setting up UIA: System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation. ---> System.TypeInitializationException: An exception was thrown by the type initializer for System.Windows.Automation.Provider.AutomationInteropProvider ---> System.Reflection.ReflectionTypeLoadException: The classes in the module cannot be loaded. at (wrapper managed-to-native) System.Reflection.Assembly:GetTypes (bool) at System.Reflection.Assembly.GetTypes () [0x00000] in <filename unknown>:0 at System.Windows.Automation.Provider.BridgeManager.GetAutomationBridge (System.String bridgeAssemblyName) [0x00000] in <filename unknown>:0 at System.Windows.Automation.Provider.BridgeManager.GetAutomationBridges () [0x00000] in <filename unknown>:0 at System.Windows.Automation.Provider.AutomationInteropProvider..cctor () [0x00000] in <filename unknown>:0 --- End of inner exception stack trace --- at Mono.UIAutomation.Winforms.FormListener.Initialize () [0x00000] in <filename unknown>:0 at Mono.UIAutomation.Winforms.Global.Initialize () [0x00000] in <filename unknown>:0 at (wrapper managed-to-native) System.Reflection.MonoMethod:InternalInvoke (object,object[],System.Exception&) at System.Reflection.MonoMethod.Invoke (System.Object obj, BindingFlags invokeAttr, System.Reflection.Binder binder, System.Object[] parameters, System.Globalization.CultureInfo culture) [0x00000] in <filename unknown>:0 --- End of inner exception stack trace --- at System.Reflection.MonoMethod.Invoke (System.Object obj, BindingFlags invokeAttr, System.Reflection.Binder binder, System.Object[] parameters, System.Globalization.CultureInfo culture) [0x00000] in <filename unknown>:0 at System.Reflection.MethodBase.Invoke (System.Object obj, System.Object[] parameters) [0x00000] in <filename unknown>:0 at System.Windows.Forms.Application.InitializeUIAutomation () [0x00000] in <filename unknown>:0 Traceback (most recent call last): File UIAutomationProvider, line unknown, in .cctor File UIAutomationProvider, line unknown, in GetAutomationBridges File UIAutomationProvider, line unknown, in GetAutomationBridge File UIAutomationWinforms, line unknown, in Initialize File UIAutomationWinforms, line unknown, in Initialize File System.Windows.Forms, line unknown, in .cctor File System.Windows.Forms, line unknown, in .ctor File System.Windows.Forms, line unknown, in get_MenuAccessKeysUnderlined File System.Windows.Forms, line unknown, in get_MenuAccessKeysUnderlined File button_label_linklabel, line unknown, in Initialize File System.Windows.Forms, line unknown, in .ctor File System.Windows.Forms, line unknown, in .ctor File System.Windows.Forms, line unknown, in .ctor File System.Windows.Forms, line unknown, in .ctor SystemError: An exception was thrown by the type initializer for System.Windows.Forms.WindowsFormsSynchronizationContext
verified, close this bug
I reopen bug because it still can reproduce in a11y-sled11-64bit, a11y-oS111-64bit and a11y-oS111-32bit
