  Further, similar approach will be taken for other properties.

IMPROVED

Form Designer ⇒ Property Pane:

• Image selection was streamlined: one button for both browsing for image files and selecting an image from URL. Furthermore, it is now possible to use images from both the application and public sources (for now, in the ‘Select image from URL’ option only). The respective prefix will be dded to the image URL in the source XML automatically: qx://application and {CONTEXT}, accordingly.

Other:

• Lycia now throws an error to a browser console in case of inconsistent theme file (e.g. containing the non-existing widget names), so it’s easier to spot the issue and make all the necessary adjustments to the theme.
• The obsolete link to the Graphical Form Editor was removed from LyciaStudio preferences, 4GL group.

FIXED

• Broken report view for UTF8 reports
• Issue with configuring properties of ListBoxItem and ComboBoxItem

  Use morphing feature in Form Designer to easily convert your existing RadioButtonList, RadioButtonListItem and RadioButton widgets to Radio.
  For more details, see Lycia tutorials

IMPROVED

Form Designer ⇒ Property Pane:

• TimeEdit: Simplified configuration
  The ‘DataType’ property will be hidden and always set to DateTime; XML attribute: dataType=”DateTime,Hour,Minute”. No changes functionality wise
• The ‘size’, ‘maxSize’, ‘minSize’, ‘preferredSize’ properties got 2 separate inline input boxes for width and height, labeled as ‘W’ and ‘H’, respectively
• Internal classes are no longer shown

Form Designer ⇒ Component Tree:

• Any system/internal components are hidden; only the items that can be controlled by a user are visible. Particularly, the GridPanel structure and visual representation in the Component Tree was simplified

Other:

• Whenever a property value is cleared via the “clear value” button, the respective attribute gets automatically removed from the source XML

FIXED

Form Designer:

• Table: Exception thrown when adding new columns
• WebComponent: Widget malfunction with GoogleMaps

Other:

• Issue with combobox not showing the selected or typed value
• Issue with the ‘onTouched’ event in FunctionField

NEW

Form Designer ⇒ Property Pane: Now you can control the content of the Property Pane through the set of configuration files.

• Decide on the default (always shown) and advanced properties (accessible through the ‘Show advanced properties’ button on the Property Pane toolbar)
• Define the properties order
• Stick to the default grouping, group properties your own way, or remove all the groups entirely

You can find more details as to where configuration files are located and how to use them in the Lycia Online Tutorials

IMPROVED

• Form Designer ⇒ TextArea: the ‘useTabs’ property renamed to ‘allowTabulation’
• Form Designer ⇒ TextArea, TextField: icons updated
• Form Designer ⇒ location properties for widgets: From now on, the location property for widgets depends on the type of the root container:
  – The ‘location’ property is available if a widget is inside the CoordPanel container
  – The ‘gridItemLocation’ property is available if a widget is inside the GridPanel container
  – The ‘borderPanelItemLocation’ is available if a widget is inside the BorderPanel container

FIXED

• Licensing: Issue with the processing of license cancellation fixed
• Form Designer ⇒ Button, Label: Fixed the ignorance of the ‘allowNewLines’ property
• Form Designer ⇒ GridPanel: Only one widget can be added to a cell
• Compiler: Fixed the issue with esqlc causing the compiler error with correct C code

IMPROVED

Form Designer:

• TextArea:
  – Dropped the ‘horizontalScrollBarVisibility’ and ‘verticalScrollBarVisibility’ properties. The scrollbar will show up automatically as needed
  – Dropped the ‘allowNewLines’ property. TextAre is always multiline
• Browser, Calendar, ComboBox, FunctionField, Label, TextArea, TextField, TimeEditField:
  Dropped the ‘fieldScroll’ property. Now, even if an input box is too small to display the entire value, you can always move the cursor to the last character of the value entered and ensure its correctness
• ProgressBar:
  Dropped the ‘orientation’ property which allowed to switch between horizontal and vertical orientation of the widget. Now, ProgressBar is always horizontal
• Forms will open in the Full Screen mode by default to make it more convenient for you to review and design the forms, with the entire design area at your disposal

FIXED

Form Designer:

• Stretching the form horizontally will no longer affect its height
• FunctionField: Removed the confusion caused by presence of two similar properties: ‘image’ (now dropped) and ‘imageid’. Now, ‘imageid’ is the only place for defining the image to be used in FunctionField

Other:

• Calendar: The date selected in the picker will always be displayed in accordance with the specified format (format always has priority over DBDATE variable)
• A few minor issues with data type conversion fixed (MS SQL, PostgreSQL)
