Controls

In the list settings, you can enter the control that you want to appear in the list.

Sometimes, it is necessary to define a specific renderer for a control, which is specified in the description of each control.

To show a selection custom field item in a list, insert a column in the relevant list and fill it in as follows:

• Expression:  zusatzfeldint('Zusatzfeldname’) for selection custom field items or zusatzfeldobj('zusatzfeldname’) for object custom field items.
• Control: cmbZusatzfeld
• Renderer: rndZusatzfeld. The renderer is needed, in the case of selection custom field items, to show the text in the selection field and not the order in the value list (0, 1, 2).

To show custom field items of a different type, do not specify a control, instead, create it directly in the control XML field. You can find a list of which controls to use for which type under the section  XML (customizing) in the article about custom field items.

Show a date picker dialog

Available from Vertec 6.3. For a date value, you can use the cmbDatepicker control to show a date picker for selecting a date:

Show a checkbox

If the value is a Yes/No value (Boolean), a checkbox can be shown in the list with the rndBoolean renderer:

As this is a renderer, not a control, it must be specified in the Renderer field. This is possible in any column that shows a Boolean value.

Asterix rows and ComboBoxes for Resource Planning

In Resource Planning, timetables  and mirrored pivot tables  support the display of an asterix row for entering new rows.

For an asterix row to be shown, the list controller must implement an add_row_object method and the Allow new entries checkbox must be set in the list settings.

To select the row object in the list, special ComboBoxes must be used, the usual ComboBoxes do not work in this context.

The following ComboBox types are available:

Customizing the ComboBoxes for asterix rows

You can customize the selection lists of the resources Comboboxes using the ListExpression.

To do this, you must specify the relevant control as an XML control via class name and define the ListExpression property.

Within the ListExpression, the usual OCL variables, such as varParent , are available.

Resources ComboBoxes may only appear in the asterix row of resource planning lists because, unlike other ComboBoxes, they select the object for a new row and do not assign a property to the row object.

Therefore, in addition to the ComboBox control for the column, you must use the rndGhostRowOnlyEditable renderer. This prevents the ComboBox from being shown in a row other than the asterix row. This is important because if this renderer is not set and the ComboBox is shown in other rows, it will overwrite existing values.

You can find further information on customizing ComboBoxes in lists in the article Customizing controls in lists .
