Maintaining Library Objects 

Library Defaults

 

Library Defaults is used to set design defaults for panels and objects in the current library. These defaults may be overridden at any time during the design process for a specific object (e.g. within the Panel Designer).

To set defaults that will be applied to all new libraries, change the settings under System Defaults.

The NOMADS Custom Title Bar feature allows you to design your own title bar to customize the look and feel of your application. A TitleBar Option is available on the TitleBar tab in the Panel Header and in Library Defaults. In addition, a custom title bar can be applied system wide by defining the %NOMADS'TitleBar$ property. See Assigning Custom Title Bars.

(The Custom Title Bar feature was added in PxPlus 2017.)

The Library Bulk Edit Utility makes it easy to apply changes to a single library or multiple libraries within a specified directory. This utility provides a convenient way to standardize the appearance of panel headers and panel controls over an entire library.

(The Library Bulk Edit Utility was added in PxPlus 2017.)

To invoke the Library Defaults window, in Library Object Selection, click the Defaults toolbar button or select Library > Library Defaults from the menu bar.

This window is divided into the following tabbed panels for viewing and/or changing Library Default settings: Setup, Display, Font/Color, User Aid and TitleBar.

(The Display and TitleBar tabs were added in PxPlus 2017.)
(The Setup tab was added in PxPlus 2019.)

Library

Displays the path and name of the current library.

Description

A free-form description to identify the library.

Setup

Library Information

Message Lib

Message Library to use when processing this library. Enter the name or click the Find Message Library button to select. If the file does not exist, you will be prompted to create the file.

Directory

Default directory to use when processing an object. Enter the name or click the Get Directory button to select. Before processing an object, NOMADS changes to the directory defined in this field. When the object is closed, NOMADS switches back to your home working directory.

Prefix

Prefix to use when processing an object. Before processing an object, NOMADS changes the PxPlus PREFIX to the one defined in this field. When the object is closed, NOMADS changes back to the original PREFIX.

User Tag Field

This user-defined field can be used to pass along information for such things as formatting, error messages, and validation rules. NOMADS places the contents of this field in a variable using the control name with a .tag$ extension. Unlike the other library defaults, this field is simply a self-documenting description text and is not passed on to controls in the library.

Library Object Selection Display

Save Sort Settings for this Library on Exit

Select this check box to save the sort order for the list of objects in the current library when Library Object Selection is exited. The next time Library Object Selection is invoked for the same library, this sort order is retained. By default, this check box is not selected.

(The Save Sort Settings for this Library on Exit option was added in PxPlus 2023.)

Display

Visual Effects

Display

Sets corresponding PxPlus mnemonic for visual mode. Available selections are Default, 2D Effect, 3D Effect, 4D Effect. Settings cannot be overridden during the design process if set. Default assumes the currently set mnemonic in PxPlus.

Attributes

Full Screen Drag

(Applicable to "Dialogue" Panels)

If selected, a panel can be moved by clicking anywhere on the panel outside of the controls (as well as on the title bar) and dragging the panel to the desired location.

The Library default is to turn on the Full Screen Drag feature (overrides the default set in %NOMADS'Full_Screen_Drag).
