Panel Header

By default, Panel Header properties are loaded when the Panel Designer is first launched. These are the overall properties used to define the panel itself, rather than the specific controls within the panel. Some changes to panel header properties (e.g. font and background/foreground colors) are automatically applied to all the controls within the panel. To reverse any changes you make, click the Undo button on the toolbar or select Edit > Undo from the menu bar.

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 and Search Utility makes it easy to apply changes simultaneously to controls in multiple panels either in a single library or in 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 and renamed to Library Bulk Edit and Search in PxPlus 2023 Update 1.)

The Wiki Help option on the User Aids tab allows Help documentation to be generated directly from a panel and displayed in the PxPlus Wiki. See NOMADS Wiki Help.

(The Wiki option for NOMADS panels was added in PxPlus 2023.)

Panel Definition

The panel itself can be selected for editing from the Panel Designer by clicking the Header option on the toolbar or selecting Panel > Header from the menu bar. The Panel Definition dialogue (pictured below using the Folder Style version of the NOMADS Panel Designer) is displayed.

Panel Header Properties

The Panel Definition dialogue consists of the following folder tabs: Display, Font/Color, Attributes, Logic, User Aids, iNomads Settings and TitleBar.

(The TitleBar tab was added in PxPlus 2017.)

The design properties displayed on each folder panel are explained below.

Panel	Display-only field that contains the name of the panel object.
Last update	Display-only information consisting of a date stamp and User ID. This information is shown when editing an existing panel.
Display
Title	Panel title to be displayed (Fixed value, string Expression or Message Library Reference).
Default Program	Default program name to be used for panel and control events (Fixed value or string Expression). Tag Field Free-form information field (Fixed value or string Expression). Precision Current precision for panel. If value is set to <Asis>, NOMADS will use the value set by the Precision directive.
Position	Determines where the panel is placed on the desktop. NOMADS provides the capability for the system to remember where a panel was last placed and will attempt to restore it to the same position. See Panel Persistence. Click the drop-down arrow for a list of selections: Absolute, Relative, Centered. Absolute (Default) The panel will be positioned on the current monitor at the Column and Line specified. The current monitor will be the main monitor for the initial screen or the monitor in use if you currently have a panel/window being displayed. Relative The panel will be positioned using the Column and Line values as relative positions based on the current panel/window being displayed. If no window is displayed, then the position will be relative top of the screen. Note: There is almost always a window logically present even if it is minimized, as PxPlus creates a main window during start up and preserves its last location automatically. Centered The Column and Line values are ignored. The panel is displayed as centered on the current display. Specify the starting Column and Line values of the panel: Column Starting column for the top left corner of the panel - numeric expression. Format mask is -##0. Valid entries are -620 to 620. Line Starting line for the top left corner of the panel - numeric expression. Format mask is -##0. Valid entries are -255 to 255. (Support for increased Column and Line maximums was added in PxPlus 2021.)
Size	Width Width of the panel in number of columns - numeric expression. Format mask is ##0. Valid entries are 2 to 620. Height Height of the panel in number of lines - numeric expression. Format mask is ##0. Valid entries are 3 to 255. Note: If adding an Info message to the panel to display pertinent user information, the height and/or width will need to be adjusted to accommodate this. To view a video presentation on how to add an informational message to a panel, go to How to Add an Info Message. (Support for increased Width and Height maximums was added in PxPlus 2021.)
Panel Transparency (0 - 100%)	(NOMADS Only) Percentage transparency for the current window. A value of "0" indicates completely opaque. A value of "100" is completely transparent.
Background Image	(NOMADS Only) Name of the picture (Fixed or string Expression). Click the Bitmap Library button to select a bitmap from the Bitmaps dialogue. Widget Panel is to be used as a Widget with the panel's defined background color transparent. Generally, a bitmap is associated with the panel.
Image Alignment	Alignment options for the background image. Available selections are Top Left, Centered, Tiled, Scaled.
Font/Color
Font Specification	Font Size Click the drop-down arrow for a list of selections.
Alignment	Sets the defaults for Fonted Text on the panel. Align Alignment for Fonted Text objects on the current panel. Selections are Left Justify, Center, Right Justify. Word Wrap Wraps text. Sets the Word Wrap option for Fonted Text. Note: Alignment, Word Wrap and Attributes such as Bold, Italics, Underline All Characters and Underline &'d Characters will apply to controls on the panel that are currently defined with default settings (i.e. Left Justify, no Word Wrap and ANSI Characters). These settings will also override the settings in Library Defaults.
Color	(NOMADS Only) Foreground Background Click the Query button to access Color Selections. Valid formats for color selections include predefined system colors (e.g. Light Red), Custom (RGB codes), HTML Hex Color Codes, User Defined colors (e.g. Color17) and string Expressions. (The Color Selections Query button and dialog were added in PxPlus 2020.)
Attributes	Optional attributes for Bold, Italics, etc.
Mnemonics	Sets the character-based attributes for Standard Text on the panel. Inverse Video ('BR') See 'BR' mnemonic. Underscore ('BU') See 'BR' mnemonic. Background ('SB') See 'BR' mnemonic.
Theme	Assign a Theme to be applied to the panel. The Theme can be defined as a Fixed value or string Expression. Click the Theme Maintenance button to launch the Themes Maintenance utility for creating and editing Themes. Click the drop down arrow to select an existing Theme. Theme names that begin with an "*" (asterisk) are predefined Themes used by PVX Plus and may be subject to change without notice. Note: A Theme applied at the Panel level overrides the General level Theme set in %NOMADS'Theme$ and the Library level Theme assigned in Library Defaults. A Theme assigned to the %NOMADS'ThemeOverride$ property overrides all other Theme settings but does not override the NOMADS Toolkit Theme. See Applying a Theme to Your Application. (Theme support was added in PxPlus 2017.) (The Theme Maintenance button was added in PxPlus 2019.) (The ability to select a predefined PxPlus Theme was added in PxPlus 2024.)
Attributes
Attributes	Dialogue Default type when a new panel object is created. The panel object is created as a freestanding dialogue box and is not constrained by the main PxPlus window.  See Note at the bottom of this page. Child Window Window is a child of the current window. See Note at the bottom of this page. Suppress.VAL If this option is Off, a suffix of .VAL$ or .VAL (numeric controls) will be added to all control names. Always on Top Panel is displayed on top of any other open windows. Menu Bar Panel has a menu bar. To define a menu bar, see Menu Bar Definition. No Windows Title Bar Panel is drawn with no Windows title bar displayed. Status Bar Panel will be created with a status line/message bar. Status Bar Segments (NOMADS Only - Available when Status Bar check box is selected) Define up to three additional (optional) status bar segments for the current panel by clicking the button next to the input control and entering the starting column number for the segment. The default segment (0) starts at column 0. Additional segments can be defined with a positive column number to specify the starting column from the left, or a negative column number to specify the start of a segment from the right. Display text in the individual segments using the 'MESSAGE' mnemonic. Example: PRINT 'MESSAGE'(text$,segnum) Where: The first segment number is 0. If the Status Bar attribute is checked and no segments are defined, the system status bar will be used. If segments are defined for the panel, they will override the system definition. Note: Use the 'MESSAGE' mnemonic to define a system status bar. Minimize Box Enables the minimize box in the top right corner of the window. Maximize Box Enables the maximize box in the top right corner of the panel. Close Box Enables the Windows close button at the top right corner of the panel. Synchro-Lock Snap position to match top lines when moved close to the top corners of the current panel. Auto Refresh The screen display is refreshed automatically when any control values are changed by the application. Auto Close Files If enabled, all non-global files opened by the application are closed automatically when the panel terminates. Size Adjustment Input objects (Multi-Lines, Drop Boxes, List Boxes and Grids) can be resized at run time by dragging their edges. See Resizing Input Controls. Note: Size Adjustment is not compatible with Full Screen Drag (see below). 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. This setting overrides the %NOMADS'Full_Screen_Drag property and the Full Screen Drag setting in Library Defaults. Available selections are: Default Use the default setting based on the %NOMADS'Full_Screen_Drag property and the Full Screen Drag setting in Library Defaults. Always on The panel will always have the Full Screen Drag feature turned On, regardless of default settings. Always off The panel will always have the Full Screen Drag feature turned Off, regardless of default settings. Note: Full Screen Drag is not compatible with Size Adjustment (above). (The Full Screen Drag option was added in PxPlus 2016 and enhanced in PxPlus 2017.) Panel Persistence Controls the ability to suppress Panel Persistence at the panel level. Available selections are: Default Panel persistence is based on %NOMADS'Panel_Info_Prog$ and %NOMADS'RelPnl_Suppress_Persistence settings. Note: The %NOMADS'RelPnl_Suppress_Persistence property applies only to panels with Position set to Relative. Suppress persistence (location & size) Persistence for the panel is turned Off. Suppress location persistence only If panel persistence is turned On, this setting causes the size of the panel to persist but places the panel in a location based on the original panel definition. (The Panel Persistence option was added in PxPlus 2019.)
Parameters	Sizing Determines whether the panel will remain fixed in size or can be resized at run time by dragging the edges of the window. Click the drop-down arrow for a list of selections: Fixed, Resizable, Resizable/Auto Scroll, Resizable/Auto Size, Resizable/Custom. Note: To make it possible for users to resize a panel larger than the defined size while still maintaining a minimum panel size, select the Maximize Box attribute and set the Sizing parameter to Resizable/Custom.
