Introduction to <strong>Visual</strong> <strong>Components</strong> 2.3<br />

If the current picture is used at the target picture, then it switches to the previous picture during runtime.<br />

For example, if Pic3 has switched to Pic4 and a picture change to Pic4 is triggered in this same picture (Pic4),<br />

then it actually switches back to Pic3. This function is especially suitable for help pages since it always switches<br />

back to the picture where it started from.<br />

This picture history only stores one picture though. This means that a picture change from Pic3 to itself would<br />

switch back to Pic4 and not the picture which switched to Pic3 in the first place.<br />

Key Type<br />

Target<br />

Picture<br />

Defines the action to occur for the touch field. The following actions are described in this section:<br />

Change Picture Switches the picture to the one specified under Target Picture. Many<br />

independent touch fields can be configured with this action.<br />

Next Picture Changes to the next picture which can be set under Target Picture. This picture<br />

is understood as a global setting for the current picture. In other words, all touch<br />

fields and function keys of key type Next Picture will always change to the same<br />

'next picture'.<br />

Previous Picture Changes to the previous picture which can be set under Target Picture. This<br />

picture is understood as a global setting for the current picture. This means that<br />

all touch buttons and function keys of key type Previous Picture will always<br />

change to the same 'next picture'.<br />

Specifies the picture to be displayed when this touch field is activated. In the case of the Next Picture<br />

and Previous Picture settings under Key Type, the respective setting is made for this picture in the<br />

key list (see above).<br />

Possible Settings Any picture in the project can be chosen from the list with the exception of<br />

the current and global picture.<br />
