GDC 2.21 new features

Discover the new features and changes in functionality introduced with Genero Desktop Client (GDC) 2.21.

Table 1. General
Overview Reference

You can now run your GDC 2.11 application with GDC 2.21 and your application behavior will be the same as GDC 2.11. This can be useful if you need to mix FGL 2.11 and 2.2x installations: you only need to install GDC 2.21.

 See the GDC 2.21 migration guide.

The internal HTTP stack has been rewritten to support pre-2.20 features and HTTP retries. This enables pre-2.20 lost features like Kerberos Support, NTLM single Sign-on or Client certificate.

GDC is also able to retry when network errors occur. This was already the case in previous (late MR) versions, but now it may retry in more situations (ex: in case of HTTP error 500). This can be useful if your network is not too reliable and sometimes messages may be discarded before reaching GAS or returning to GDC. You can now configure how GDC will retry:

Table 2. Windows
Overview Reference

The Genero Desktop Client automatically displays scrollbars around the form when the window is larger than the desktop size.

This old feature has been completely reviewed to now work also when the window is not maximized. GDC will then automatically, when the window is larger, fit the size of the window to the desktop size (height or width) and display scrollbars around the form.
Note: This feature should be used carefully. A Desktop application is not a web application, and having scrollbars (especially horizontal ones) around the form is not common. As GDC will try to always show the current field, this may lead to lots of scrolling when you move from one field to another if the fields are not all visible.

We strongly recommend that you adapt your forms to the smallest desktop size you target; automatic scrollbars should only appear for "accident" cases.

If you prefer avoid automatic scrollbars and retrieve the behavior of previous versions (only getting scrollbars when the current window is maximized) you can use the following style attribute:
<Style name="Window.myWindow">
  <StyleAttribute name="formScroll" value="no">
</Style>
To achieve automatic scrollbars in a more stable way, the action frame (menu/dialog) has been reviewed. The new look is very slightly different, but the main behavior is the same.
  • Navigation button are different if you are on the first or last row.
  • A "plus" button has been added to display in one click all remaining items.
  • A little animation shows scroll direction.
 See the Window style attributes topic in the Genero Business Development Language User Guide.

As well as "maximized", windows can be started minimized using minimized as the value for the "windowState" style attribute.

See the windows style attributes section in the Genero Business Development Language User Guide.
Table 3. Widgets
Overview References

DateEdit now has a presentation style named "showCurrentMonthOnly". This style configures whether the calendar shows only the current months, or displays (in light grey) days of the previous and next month.

See the DateEdit style attributes section in the Genero Business Development Language User Guide.

You can now set a range on the SpinEdit widget with the new attributes valueMin and valueMax.

 See the SpinEdit item type section in the Genero Business Development Language User Guide.

Image field now supports style attribute "alignment" to define where the picture should be located when the container (widget) is bigger.

 See the Image style attributes section in the Genero Business Development Language User Guide.

Window supports new style attribute "toolBarDocking" to define if the toolbars are movable and floatable.

You can now set a point font size with a non-integer value, for example 8.3pt.

Table 5. Monitor
Overview Reference

The Connection tab now displays both the application name and text.

 See the Connection configuration options topic.

Users now receive an error message if the number of user licenses is exceeded. User Limit exceeded is now a default terminal string, so the end user has feedback if the application can't start because of a license issue.

 No additional reference.

Debugging information has been added to the debug console when a shortcut starts. Analyzing this log may help you to understand what GDC did, and why a connection may have failed.

GDC 2.21 has been adapted to work with WinSSHd 5.0.9 (some changes in the server have been done by Bitvise too, so you'll need to upgrade the server part to at least version 5.0.9.)
