• If a visualization is used as Target-Visualization, information on user entries via
mouse-clicks can be scanned with the help of special interface functions and thus
be used in the project.
Note!
You can find descriptions on the online usage of some visualization elements, like
e.g. Trend or Table, in the help page on the configuration of the respective element.
20.10.1 Operation over the keyboard - in online mode
In order to get independent from the mouse or a touch screen, it is useful to configure
a visualization in a way that allows pure keyboard operation:
Per default the following key (combinations) will work in online mode anyway (no
special configuration necessary):
• Pressing the <Tabulator> key selects the first element in the element list for which
an input is configured. Each subsequent pressing of the key moves one to the next
element in the list. Within tables you will jump to the next table field. Pressing the
key while keeping the <Shift> key depressed selects the previous element.
Depending on the target a simplified input handling may be possible.
• The arrow keys can be used to change from a selected element to a neighbouring
one in any direction.
• The <Space bar> is used to execute an activity on the selected visualization
element. If the element is one which has a text output variable or if it is a table
field, a text input field will be opened which displays the text contents of the
variable resp. the field. Pressing the <Enter> key writes in this value.
Additional key (combinations) for the online operation can be defined in the
configuration dialog 'Keyboard usage'. There also the keys <Tab>, <Space> and
<Enter> can get assigned another functions than the above described standards.
The individual elements of references behave in Online mode identically to the
corresponding ones in the visualization that is referenced. They will therefore react
the same way as individual elements to inputs and operation by mouse and keyboard;
the display of tooltips in references is also element-dependent. When processing the
element list, as for instance when jumping from one input element to the next using
the tabulator, the processing of all individual elements of a reference proceeds from
the location of the reference in the element list before jumping to the next element of
the list.
