When you deploy an application to your customer, either a merged 4D Server or Single User application, 4D usually opens the “Select data file” dialog. This happens because for an updated solution 4D cannot find the position of the last used data file, as you just replaced the old structure. And for a first time usage, 4D does not know where you would like to create the data file – so it asks for the location.
This dialog, as the very first interaction with your application, might be confusing for the customer. And the verification for the data file happens before the On Startup is executed, before your code has a chance to select another file. To avoid this, 4D v15 introduces a new feature, named Default Data.
Easily create flexible and powerful UIs, dialogs and widgets with 4D View Pro! To know more about 4D View Pro, check out this blog post.
This feature is a powerful enhancement for the listbox object, providing you with a mean to define very flexible UIs. An array of objects can now be associated with the column of a listbox so that each cell can have different types of widgets according to the type of data to be displayed.
We have identified a large set of usages of 4D View in customer applications. One of them is an enhanced user interface using advanced lists, such as a property window for instance. Others are using 4D View to have detailed control of list display, requiring a large set of fine details not available in list boxes.
We also saw usage of 4D View as a reporting engine as well as a spreadsheet. As a result, 4D View Pro could not be a single solution or tool to handle all this cases.
Now, you can start 4D v15.0 in a given language while your Mac OS system language is different. For example you want to start 4D v15.0 in Spanish on an English OS X.
