On resize… On resize… On resize…

Automatically translated from English

Wondering how to create a nice and dynamic user interface? Typically when a form is resized, the form objects whose horizontal sizing or vertical sizing properties are set to move or grow, are automatically resized. In some cases  (e.g., finer user interface management), developers choose to manage form object size and position by programming. To do so, they check the “on resized” event which is triggered within the form method. But what happens when the form contains one or more subforms? On many levels? This blog post gives you the answers!

Multiple 4D data sources, interested?

Automatically translated from English

We’ve got an exciting new feature to announce in 4D v18 and the title may have already given you a hint!

This feature opens new possibilities for client/server work. Rather than being limited to the current database and requiring a permanent network connection, an application in 4D v18 can get data from another, remote 4D database that’s exposed on a 4D server!

A lot of options become available thanks to this feature. For example, you could organize your applications to work offline and only synchronize local data when remote data is reachable. Or you could consider publishing your data on multiple servers and switching from one to the other as necessary. Another option could be splitting your data model across different databases (e.g. local data, international data). What about having your data distributed in different places yet still accessible through a single 4D client code (project methods and form objects)? All of these scenarios are now possible and this blog post tells you how!

CSS color strings for better readability

Automatically translated from English

Improved and simplified 4D commands just keep coming. Now you can set colors in your form objects using CSS strings instead of numeric values. Previously CSS colors for objects were declared with a 4-byte longint (e.g., 0x00RRGGBB). But if you feel more comfortable writing BLUE instead of its numeric equivalent 255 (0xFF), we’ve got good news … 4D v17 R6 makes it possible!

A new tool at your fingertips to analyze debug logs

Automatically translated from English

With 4D v17 R5, we’ve improved the debug logs by adding methods and allowing each process to be traced independently. With this R-release, we’ve gone a step further by shipping a debug logs analyzer tool to help you monitor process execution. You’ll be able to see which processes are the most consuming, the call chain with the corresponding running time, and much more.

Retrieve the current execution call chain

Automatically translated from English

When programming an application, you may need to know where you are in your code, especially when one method calls other methods, which may then call other methods. That’s why it’s very helpful to see the chain of methods, or the call chain, during the debugging process. For this, 4D v17 R6 provides the new Get call chain command to give you an insight into the executed code. Now you won’t have to worry about getting lost anymore!

Tips

Write generic code with the latest ORDA features

Automatically translated from English

ORDA has its share of features with 4D v17 R5, including various ways to write generic code.

Writing generic code allows you to centralize your code to facilitate updating it. Not only does it enable you to write reusable code that can be used in different use cases, freeing you from having to reinvent the wheel again and again, it also lets you add extra functionalities on top of what you’ve already done.
