Elevate Web Builder 2.02 Released

---

Posted by Tim Young on Tue, Oct 13 2015

Elevate Web Builder 2.02 is now available for download. If you're an existing customer, then you should be receiving an email shortly with download instructions.

2.02 Breaking Changes

---

The following are breaking changes in Elevate Web Builder 2.02:

• The TInterfaceManager.Scheduler property has been removed, replaced with a new async keyword (see below for more information on this).



• Layout consumption is now based upon the maximum consumption rectangle now, instead of the last element's consumption rectange. This provides a more logical layout behavior, especially with flow layouts.



• The "Hot" control interface state is now given preference over the "Focused" state with mouse-overs.



• The TPanel control interface's Visibility propety changed for the Client element.



• The TPanel control interface's Base and Client element backgrounds are now styled differently in order to allow proper use with height animations.



• The TGrid*Cell* control interfaces all contained incorrect Focused and Both state property settings for the Border.Top property that would cause unnecessary interface updates during grid cell updates. They should have been the same as the other interface states.



• The TMenu control interface Padding and Background.Fill.Color property settings added for the Client element.



• The TEdit, TMultiLineEdit, TEditComboBox, TFileComboBox, TGridEdit, TGridEditComboBox, TGridTextCell, TGridTextCellWithLines, and TGridColumn control interfaces' default Font.Color property changed to clElevateLightBlack in order to provide more contrast for editable text.

2.02 Improvements

---

The following are included improvements in Elevate Web Builder 2.02:

• The compiler now supports a new async keyword for executing function/procedure calls asynchronously.



• The TGrid control navigation/load performance as been greatly increased.



• There is a new OnAnimationComplete event for all controls that support animation.



• The entire selected row is now highlighted for the "Hot" interface state in the TGrid control when its RowSelect property is True.



• There is a new TBalloonLabel control and control interface added for displaying text in a word balloon.



• There are new OnEnter and OnExit events for the TMenu control.



• There is a new TMenuItemSeparator control interface.



• There is a new TMenuAddSeparatorButton control interface.



• There is a new DropDownPosition property for the TEditComboBox, TDateEditComboBox, TButtonComboBox, and TGridColumn controls for specifying whether the associated drop-down control should be placed relative to the owner control's position, or positioned in the center of the application surface.



• There is a new Responsive Panels example project added that shows how to use the layout overflow functionality to create flow layouts.



• New keystrokes in the form/control interface designer: the up/down arrow keys select controls/elements in layout order and the ctrl+up/down arrow keys select controls/elements in tab order, making the selected control/element visible, if necessary. This is useful for verifying layout/tab ordering, as well as finding any "stray" controls/elements that are not visible because they are beyond the bounds of their container.

Elevate Web Builder 2.01 Released

---

Posted by Tim Young on Wed, Aug 26 2015

Elevate Web Builder 2.01 is now available for download. If you're an existing customer, then you should be receiving an email shortly with download instructions.

2.01 Breaking Changes

---

The following are breaking changes in Elevate Web Builder 2.01:

• The parameters for the TReader constructor and Initialize method have been changed.



• The class for the TImage ContentLayout property has been changed so that it mirrors the background image layout options. You will need to reset the ContentLayout property settings for any TImage controls created using the initial Elevate Web Builder 2 release.



• Per this incident report:
  
  # 4196 Line Separators Incorrectly Set to Only LF Instead of CRLF in List-Based Controls
  
  the TListBox, TEditComboBox, and TButtonComboBox Items properties, as well as the TMultiLineEdit Lines property must be reset if they have been assigned values at design-time using the initial Elevate Web Builder 2 release.



• The Elevate Web Builder Web Server now automatically handles cross-resource origin headers for modules, so you do not need to manually handle such HTTP headers in your module code.



• The Elevate Web Builder Web Server now automatically assigns URL authentication parameters (user=<UserName&password=<Password>) to the RequestUser and RequestPassword properties of the incoming TEWBServerRequest instance passed in to web server modules. This is in addition to alread automatically handling any custom Elevate Web Builder HTTP authentication headers (X-EWBUser and X-EWBPassword).

2.01 Improvements

---

The following are included improvements in Elevate Web Builder 2.01:

• A new TControl Animations property that can be used to set up animations for the Left, Top, Width, Height, Opacity, and Visible properties of controls.



• You can now use the TLayout Overflow property to implement flow and responsive design layouts.



• There are new TCalendar and TDateEditComboBox controls for date selection.



• There is a new TMenu control for displaying vertical menus.



• There is a new TIconButton control for using icons like buttons.



• The TButton control now has an Icon property that you can use to specify an icon that will appear to the left of the caption on the button.



• There is a new TMap control for accessing Google Maps, including geocoding and marker support.



• There are new ctIcon, ctImage, and ctDateEditComboBox TGridColumnControlType members for the TGridColumn ControlType property, allowing icons, images, and date edit combo boxes to used with grid columns.



• There is a new TGrid AlwaysShowControls property for ensuring that grid column controls are always visible and don't need to be specifically enabled.



• You can now control the appearance of individual cells within a grid column using the TGridColumn OnCellUpdate event.



• There are new TGrid OnColumnChanged and OnRowChanged events for detecting when the grid's ColumnIndex and RowIndex properties change.



• There are new TGridColumn OnEnter and OnExit events that are fired as focus shifts to or from a grid column.



• For un-bound grids, you can now sort the rows using the TGrid SortRows method. In addition, you can use the TGridColumn OnCompare event to customize the sort.



• For un-bound grids, you can save/load grid rows to/from JSON using the TGrid GetRows and LoadRows methods.



• There is a new TServerRequest Timeout property (and a corresponding TDatabase Timeout property) for specifying request timeouts.



• There is a new Refresh method for the TImage, TPlugin, and TBrowser controls for refreshing their content without having to modify their URL property. This is useful when the content changes on the server, but the URL does not.



• There is a new TDialogCaptionBar AllowMove property that can be used to specify that a TDialog can be moved by dragging the caption bar, and a corresponding property for the TPanelCaptionBar and TPanel controls.



• There is a new TControl DefineLayout method for "pegging" a control to its current layout bounds.



• There is a new public (not published) TControl ClientID property that you can use to specify the unique HTML ID for the client UI element of a control. This is useful when you need to identify the element from external JavaScript.



• The emit clause for external classes now allows for namespaces with periods (this.is.a.namespace).



• The compiler now includes support for function/procedure references.



• The Ord function can now be used with Boolean values (0=False, 1=True).

• The TReader and TWriter classes now include a DateTimeFormat parameter in their constructors for specifying how date/time values should be handled when being read/written as JSON: as raw integer values (the default), or as ISO 8601 strings.

• New project, unit, form, and interface file naming is more logical now, and based upon the contents of the applicable current directory, as opposed to a base name with an ever-increasing, incremented file name suffix

• New responsive layout example project that demonstrates how to build a responsive layout using the new TLayout Overflow property.



• New PDF Client and PDF Module example projects that show how to dynamically return a PDF file as a content response from an Elevate Web Builder module.
