Multi-Touch features in zenon 7.20
The way we interact with computers has changed in recent years and since then most people are used to directly manipulating interfaces by using gestures. Also with zenon Multi-Touch features the user literally stays in touch with what is going on in the work process. In zenon 7.20 we equipped the operator with new Multi-Touch features, which can easily be adapted.
Frames can be moved without having a title, a system menu or a min/max button. Also freely definable frame shapes can be used for native interaction. To illustrate how to create such frames, let’s have a look at the login screen of the zenon Supervisor demo project as an example:
Create a new frame with a freely definable frame shape and give it any shape you like. In the demo, a rectangle and a polygon with rounded corners was used. After creating a freely definable shape, position the frame where you initially want to have it in the RT.
Now, to make the login frame movable, go to the frame’s property settings, activate “always in the foreground” and set the following positioning settings: Opening size as “frame size”, no limitation minimum and restrict the movability to display borders. The property “minimum frame margin” defines, how many pixels of a frame have to remain on the RT monitor and cannot be pushed outside the screen (however, in the case of free shapes only the bounding rectangle is considered). In the demo project, 70 px were defined as margin.
Afterwards, create a screen with this frame. Now comes the “creative” part: Fill the screen with elements (rectangle, templates, adapted tem¬plates, symbols…), align them and link functions and variables as usual, until you have your desired screen result.
When creating a faceplate screen with different screen containers such as an Alarm Message List, a Chronological Event List or trend elements, you now can use it as worldview as well. For instance, this feature could become interesting if you want to have an overview of a whole site containing several alarm or trend screen containers within one (touch) screen. The other way round, you can also use the screen container for displaying a worldview, e.g. when you want to display a touchable menu slider.
