4D Write Pro: Handle view properties by programming

Automatically translated from English

4D Write Pro documents can be displayed in different modes (draft, page and embedded), each with their own viewing options. For example in Page view mode, you can choose to hide both the vertical and the horizontal rulers, but keep the headers and footers visible. The same goes for many other display properties such as zoom, spell check, page frames, etc. Thirteen different viewing options can be defined. The good news is that rather than handling all of these properties manually, it can now be done programmatically.

HDI: View settings

4D Write Pro view settings are not a part of document. This is what enables having multiple view modes for a single document. A typical example is to display the same document differently, according to the context. When you read a document, horizontal and vertical rulers are usually useless. It’s the same for spell check and page frames. But you do want to see the background so you can get a good idea of the final print rendering.

New commands

Scenario: I want to see the page frames, but I don’t need the spell checker…

Use the WP SET VIEW PROPERTIES command:

WP SET VIEW PROPERTIES(*;"WParea";New object(wk visible page frames;True;wk auto spellcheck;False))

What about getting the properties already set?

The settings are returned by the WP Get view properties command. It returns an object with all of the view properties at once!

Check out the HDI to see the new commands in action. More details can be found on the doc center.
