Meaning
The image box control manages a picture in bitmap or GIF format. If the picture is larger than
the displayable area, the control will show a scroll bar.
To control the visible area, the system provides the function CONTROL.IMAGEBOXSET (see
Chapter "Predefined functions (Page 81)").
Syntax:
<function name="control.imageboxget"> ... </function>
This tag defines the help topic to be called. It should be programmed in the INIT block.
The name specified in the attribute is supplemented by the prefix XmlUserDlg_ and is trans‐
ferred to the help system. The associated structure of the help file should be taken from the
topic - generating an online help.
Sequence when activating the help system:
1. Press the "Info" key.
2. The dialog supplies the expression "my_dlg_help".
3. Parser converts the expression into "XmlUserDlg_my_dlg_help" .
4. Activating the help system.
5. Submitting the search term "XmlUserDlg_my_dlg_help".
Syntax:
<HELP_CONTEXT name="<context name>" />
Example:
...
<INIT>
...
<CAPTION>my dialogue</CAPTION>
<HELP_CONTEXT name="my_dlg_help" />
...
</INIT>
The tag controls the behavior of the dialog forms when user inputs are being saved.
The behavior should be defined within the INIT tag.
If the tag is not used, inputs are buffered in each case.
Exception: Controls for which the hotlink attribute is set to true are always written to and read
directly.
Attribute::
● type = "TRUE" – the input values are not buffered. The dialog form copies the input values
to the reference variables directly.
● type = "FALSE" – the values are only copied to the reference variable with the
UPDATA_DATA type = "FALSE" tag.
Example:
<DATA_ACCESS type = "true" />
