User of process D2000 HI can work with structures (objects of Structured variable and Database tabletype) in two ways - by means of dialog box or displayer of Browser type placed in the picture.
...
An example of Browser displayed in D2000 HI:
To create Browser displayer
- In the Drawing toolbar, click the button Browser
. - Point the mouse cursor to the position of the first displayer corner and click.
- Point the mouse cursor to the position of the diagonal displayer corner and click.
...
The parameters of Browser displayer can be configured in the palette Connect object through the following tabs:
Connect
...
| 1 | Selection of an object of Structured variable or Database table types, which will be displayed in the Browser. |
| 2 | Selection of a local variable, which will be displayed in the Browser. |
| 3 | Selection of a structure to control. |
| 4 | Selection of a local variable to control. |
...
Controlled object
The parameter Controlled object row is optional. If a controlled object is defined, it (Structured variable) must contain the same structure definition as the displayed object. A defined row of the controlled structure will obtain values according to the currently displayed row. If any row is not selected, the last set values remain in the items in the row of controlled structure variable.
...
This parameter specifies which row of the controlled object will alter its value. Such an object can be used as e.g. an input parameter for an Event executing some activity according to a row selection in the Browser.

...
If checked, the condition specified below is applied to the table immediately after opening a picture and the table is filled with the items matching the criteria. Otherwise, after opening a picture the table remains empty. The desired condition is still available, though. However, to be applied, the function %HI_RefreshData must be called.
Condition
The input edit box to define a selection condition. A result set will include the objects matching the given mask. Condition syntax is identical with the syntax of condition following the clause WHERE in the SQL command SELECT (e.g. NAME= 'Test' or VALUE < 32.5).
Entering the condition #empty# doesn't read any data into the Browser (it can be used to open a Browser, whose condition is generated automatically on opening the picture from the script).
