Today, big screens are everywhere. At the airport or train station for arrival/departure. In production areas for failure/success or production numbers. In call centers for activity or calls in queue. In stock exchange for a ticker.
Your first thought could be to use a normal computer, macOS or Windows, with a “27” or 30” screen. Expensive, but easy to do. But besides the high price, you need to run a 4D app, launch it, update it, all just to display a picture?
According to neuroscientists, we respond better and faster to a visual form than any other type of representation. That’s why graphs and charts are clearly a key to a better understanding of data.
So if you’re looking to display bar charts, histograms, or pie charts which are modern and fully compatible with the leading browsers, but also more suitable for the way the human brain processes information, Google Charts is one possible answer. The available chart types in Google Charts is varied: from the classical bar/column/pie charts, Google Charts also offers elaborated graphs such as Treemap, Candlestick and Gauge charts.

Hot news! 4D applications on Windows are entering a new world thanks to 4D Windows 64-bit. Do you remember the grey-background main window which contains all other application windows? This main window is technically called MDI (which stands for Multiple Document Interface) and now there’s a way to get rid of it and move to SDI (Single Document Interface) where application windows are all independent…
Interested? Just activate the SDI mode with a single checkbox and it’s done…without a line of code!
A less well known usage of 4D Write Pro product is the production of HTML emails. In fact you can create a 4D Write Pro document including 4D expressions, text and images, then modify the document, paragraph or text properties and send it by email. In this context, a very common need is to add a link to a picture, e.g. your company logo.
4D Write Pro has been enhanced with 4D v16 R4 so that hyperlinks can now been added to text and/or pictures. Setting a link to your company logo or company name is now as easy as styling some text to bold.
4D gives you new possibilities to customize your 4D Write Pro user interface to make it perfectly fit your business application. Instead of using the default 4D Write Pro contextual menu, which is so detailed that it could become unpleasant to use, the 4D developer can create its own contextual menu, with the exact list of actions that he wants to provide.
You want to quickly create a toolbar for your Styled text areas. You want to change the font of the text or compute/freeze 4D Expressions without writing a line of code. It is possible using the new standard actions for Styled Text areas.
Just associate a standard action to each button object and 4D will handle everything automatically: action triggering but also the button activation or deactivation if the action is not available in the current context.
Thanks to macOS Sierra, applications now have to opportunity to use tabbed windows instead of multiple windows. From 4D v16 R3, 4D Developer Edition 64-bit can take advantage of this Apple’s new feature for the design environment.
The type of windows that can be tabbed are Methods and Form Editors windows. Other windows as explorer or tools for instance remain separate.
As in every application based on tab windows:
- each tab can be moved to a new window by dragging the tab out of the tab bar.
- each tab can be moved to another existing window.
