Display Options Form

Use this form to modify the UI of a library.

Field Description

For Objects

This section contains two tabs, one tab for Library specific settings (for example, overrides and icons) and another tab for View specific settings.

The only option currently in the latter tab is for Show extended states, which turns on or off DM queries, and other information that is displayed in the tables of the Library Manager window - views and files.

Switching this option off restores the display behavior.

Display Overrides

Lets you override custom display settings for libraries.

Show all libraries using standard style

Overrides any custom display settings and displays all libraries in the default style.

Show hidden libraries

Overrides any invisible settings on libraries and displays all libraries.

Show library colors

Displays libraries in the customized colors.

Show custom library icons

Displays custom icons for libraries. Icons are visible in both the Tree view and Lists view.

Show Lists view library icons

Displays custom icons only in the Lists view of libraries. Icons are not displayed in the Tree view.

State Analysis

This section allows you to set the Design Management states.

Enable query of Design Management states

Deselects this option if your Design Management performance is slow and impacting library browsing speed. Consequently, Design Management icons does not get displayed and related Design Management state is shown as empty in the Library Manager extended tables.

This option and Show extended states must both be set to on in order to see DM states in the main Library Manager window.

The Enable delay before DM syncs option enables you in quicker browsing when slower DM integrations for GDM are in use and you do not want to turn off the DM display feature entirely. This option is enabled once you select the Enable query of data management check box.

The DM gets queried on a selected item, such as a cell, including its views and any other files, are displayed n seconds after the current cell is selected in the list. The select action loads the item's contents, which includes views and files of the specified cells into the list display.

The value in the Wait field (in seconds) comes from the .cdsenv DB setting. By default, the value is 2.5 seconds. The accepted values are 0 through 999 seconds. Set the wait time value higher if you know that your DM system gets slow in responding to such queries. Once your selection/browsing has stopped, and the Wait delay time-out is reached, the DM system is then queried to update the DM status display in the window for the current library or cell contents.

Enable delay before DM syncs

Enables a delay in the time period between when a cell was selected and when the Design Management status requests gets called for it. A delay enables you to quickly select between several different cells in a library without the updated DM status being obtained for all of those cells. You can set the delay period by specifying the units in seconds in the Wait …seconds after selecting field.

By default, the Enable delay before Design Management syncs check box is not selected.

Enable poll

Reanalyzes states periodically, based on the two slider and spin-box value settings for the related options, as follows:

Interval

Sets the number of seconds to determine the time setting between successive reanalyze state queries.

Idle limit over interval

Determines how long the polling should continue after the last UI interaction. The seconds value set here is added to the interval seconds set.

The polling features enable state change detections without external notification channels, such as Design M check out from another system, workarea, and/or user. Some common edit operations in Virtuoso also notifies the Library Manager. In such cases however, the polling settings are not used to update values.

Design Management systems that support large number of clients should advise users to select longer poll intervals in order to prevent overwhelming shared resources. The fastest interval value is 1 second, while the default is 30 seconds. These poll settings can be obtained by referring to the .cdsenv file. Virtuoso edit notifications occur independently of poll settings. Fast poll intervals are therefore not necessary here and may impact all user’s DM operations.

Resources

This section includes an option to customize the display settings.
