Implemented Feature Requests

PR Description Comments
77Set the default button in Alerts.added setInitialValue() API
236Right-click in table/list/tree/table tree should update the selection before popup menu is displayed 
361ULCAlert: setMessage without effect after upload 
366IFileStoreHandler.prepareFile should have a throws clause 
414provide labelFor property on ULCLabel 
425add set2DigitYearStart/get2DigitYearStart to ULCDateDataType 
436Filler space in table and table tree should behave like regular cell space Table and table tree now always expands in height. Nevertheless there still might be some filler space at the right side when the auto expand mode is turned off.
438We need the possibility to set a specific locale on ULCNumberDataType  
441The size/location of an internal frame can not be set anymore once the internal frame has been added to the desktop. 
442Map ESC key to window close box Dialogs 
461Table / Tree / TableTree ActionEvent handling is conflicting with default Swing behaviorAction events are generated only if there is an action listener registered with a widget.
Action Events on tree are generated
  • when the user double clicks a leaf
  • when the user presses enter in a node which is not being edited
Action Events on table and table trees are generated
  • when the user double clicks a non-editable cell
  • when the user presses enter in a cell which is not being edited
463When pressing a modifier key (CTRL, SHIFT, ALT) during a synchronous event the UIEngine permanently beeps 
464missing remove in ULCMenuBar 
472Logger should also provide some low level logging methodsadded the following methods:
  • log(Level level, String msg)
  • log(Level level, String msg, Object param1)
  • log(Level level, String msg, Object[] params)
  • log(Level level, String msg, Throwable thrown)
473Output of SimpleLogManager should be enhanced (tab separated, more info) Added SimpleLogManager.setMessageFormat() API.
Default format is: "{0}\t{1, date, dd.MM.yyyy HH:mm:ss.SSS}\t{2}\t{3}\t{4}\t{5}\t{6}\t{7}\t{8}" where
  • {0} is replaced by a sequence number
  • {1} is replaced by the current date as text
  • {2} is replaced by the level value
  • {3} is replaced by the level as text
  • {4} is replaced by the current thread as text
  • {5} is replaced by the class name
  • {6} is replaced by the method name
  • {7} is replaced by the msg
  • {8} is replaced by the parameters as text
474add more log message to the ULC frameworkAdded
  • log lifecycle log message with level INFO
  • server rount trip log messages wiht level FINER
  • request log messages with level FINEST
  • exception log messages with level SEVERE
  • warning log messages with level WARNING
Logging can be turned on
  • in ServletContainerAdapter with setting the init parameter 'log-level' to ALL
  • in DefaultAppletLauncher with setting the applet parameter 'log-level' to ALL
  • in DefaultJnlpLaunchner with passing ALL as third parameter to main
  • in DefaultStandaloneLauncher with passing ALL as third parameter to main
480Hard coded empty border of ULCHtmlPane should be removedTo have a ULCHtmlPane with the old empty border put it inside a ULCBoxPane with a margin of 10.
485Using "static" (=application wide valid) variables in ULC is cumbersome Introduced ApplicationLocal class.
487KeyEvent should also hold information about the modifier key 
488Add version check during startupWhen the server starts up all used ULC libraries are checked.
When the UIEngine starts up all used ULC libraries are checked.
When the UIEngine connects the server and client versions are compared.
489Client side exceptions. 
492null font name should result in default font as in swing 
498provide ULCLabel.setIconTextGap(int iconTextGap) 
499Context-help (F1) does not work for several components 
514ULCNumberDataType should support leading zeros (e.g. 00123). 
531default values for ULCNumberDataType that is an Integer field 
539Method to paint "borders" and "focus" in ULCButtons 
544FileChooserConfig should give the possibility to visualize and to select only directories 
545Buttons in ULCAlert do not support mnemonics 
546ULC should support SystemColors 
548add byte[] constructor for ULCIcon 
549Containers holding one cell should all provide same API: add(), remove() The following containers are one cell containers:
  • ULCFrame
  • ULCDialog
  • ULCBorderPane
  • ULCInternalFrame
Adding more than one component now throws an exception.
Removing a component from an empty one cell container now throws an exception.
