SET DISPLAY

This chapter documents the SET display family of commands applicable to STx DISPLAY items (i.e. shell items of type DISPLAY).

SET display subcommand …

For a list of DISPLAY item attributes, see DISPLAY Item Attributes. For a short first introduction into the matter of DISPLAY items, see Introducing Display Items.

Graph Control

The following commands are used to set the height and width of the window in which a graph is displayed, as well as assigning the graph itself.

GRAPH

SET display GRAPH graphitemname

Activate a graph attached to the display. The activated graph gets the keyboard focus.

HEIGHT

SET display HEIGHT h₁ [ … h_Nrows]

Set the height of all graph rows relative to one another. The height of the display window and of the dialog is not changed. E.g. SET display HEIGHT 1 1 2 sets the height of row three to the double of the height of rows one and two.

h_X

The relative height of the row X (1 … number of rows).

WIDTH

SET display WIDTH row|* left right

Set the width of the columns of the specified row (row ³ 0) or all split rows (row = *). The column splitter position is computed using:

pos = left / (left + right) × display_window_width.

`left`	The relative width of the left column (`left` ≥ 0).
`right`	The relative width of the right column (`right` ≥ 0).

Graph defaults

The following settings are not directly used by the display. They define the default settings for graphs which are created after the display. For a detailed description see the section SET GRAPH. Only the argument title (of SET display TITLE) is actually used by the display as the window caption (the text in the top left corner of the window).

Popup Menus

ADDPOPUP

SET display ADDPOPUP title item₁ item₂ …
SET display ADDPOPUP title table /Table

Add a popup menu to the display. The popup menus are displayed in the menu bar of the window in the same order as the ADDPOPUP commands are issued. Here is an example.

When a user selects an entry from one of these popups, the display item is sent a POPUP message.

title The menu title which is displayed in the menu bar of the display.

item_X

The menu items. item_X is used as the menu item capture unless the following applies:

The string item_X is an asterisk - a menu separator is added rather than a caption.
The string item_X begins with the character '>' (e.g. >text) - A submenu is defined using text as the caption.
The string item_X is the character '<' - the last opened submenu is closed.

If you want to display a hotkey in the menu item, add a tab and the hotkey to the item text, e.g. "Open [tab] Ctrl+O".

table

A simple table with one item per entry. See item_X for item details.

Separators or items which start or end a submenu are not counted in the menu item index computation!

SETPOPUP

SET display SETPOPUP index1 [...] [/Enable|Disable /Check|Uncheck]

Activate|deactivate and/or set|clear the check status of menu items. The items may be located in different menus.

The index of menu items is used in the message handling and for the SETPOPUP command. It is computed as follows:

index = menuIndex * 100 + itemindex

`menuindex`	index of menu (0, 1, ..; leftmost = 0)
`itemindex`	index of item in addressed menu (0, 1, ..; topmost = 0); separators and submenu headers are not counted

DELETEPOPUP

SET display DELPOPUP|DELETEPOPUP

Delete all popup menus and hide the menu bar.

Print

SET display PRINT CLIPBOARD

Copy the display to the clipboard

SET display PRINT filename

Save the display to the file filename

SET display PRINT PRINTER

Print the display

Print or save all graphs contained in the display (this does not include the dialog). The options /Print and /Screen are used to select the color scheme. For file output, the file format is selected by the options /Enhancedmetafile (*.WMF), /Bitmap (*.BMP) or /pnG (*.PNG). Once started, the operation is performed in the background and a STOP message is sent when finished.

Toolbars

A set of toolbars can be added to each display. Each toolbar consists of the buttons specified in the ADDTOOLBAR command and can be identified by an index (>0). If a button is assigned to more than one toolbar, it has the same meaning and message id in all toolbars. Toolbar buttons can be used like buttons (press) or switches (turn on/off). The set of defined toolbar buttons (see Appendix) is very small at present but will be expanded in the future as needed.

SET display ADDTOOLBAR index title button1 ...

Add a toolbar to the display.

index

The toolbar index (> 0).

title

The title of the toolbar window. This is only displayed if the toolbar is floating.

buttonX

The id of the toolbar button (see the Appendix for a list).

SET display SETTOOLBAR index /Visible|Hidden

Show or hide a toolbar index.

SET display SETTOOLBAR button1 ... [/Enable|Disable /Check|Uncheck /Button|Switch]

Set state (/E|D, /C|U) and mode (/B|S) of all listed toolbar buttons (button1 ..). If a button is member of more than one toolbar, the state/mode is changed in all toolbars.

SET display DELTOOLBAR|DELETETOOLBAR index

Delete the toolbar index.

Window Layout

SET display mode|* [style xpos ypos width height] [/Centered /Foreground /Dialog /View /Layout /Modal=itemId]

Set the display window mode, style position and size and configure the dialog.

mode

The window mode. Possible values are NOWINDOW (the window is hidden and disabled), HIDDEN (the window is hidden), VISIBLE (the window is visible but disabled), ENABLED (the window is visible and enabled) or an asterisk if you do not want to change the window mode.

style

The window style. Possible values are MINIMIZE (the window is minimized to the taskbar), MAXIMIZE (the window is maximized to take up the whole monitor display) or RESTORE (the window is restored to it's normal size).

xpos

The left coordinate of the window in pixels. The left most pixel on the display is 0.

ypos

The top coordinate of the window in pixels. The top most pixel on the display is 0.

width

The width of the window in pixels.

height

The height of the window in pixels.

/Centered

The window is displayed in the center of the screen; xpos, ypos, width and height are ignored.

/Foreground

The window is displayed as the top-most window. Note that a window that is top-most is always visible and enabled, therefore the mode parameter is ignored when this flag is used.

/Dialog=pos

Set the dialog position inside display (relative to the graphs); changing the position is only possible if the dialog is non-floating pos = ABOVE|BELOW|LEFT|RIGHT;

/View=view

Set window view mode to view ('WINDOW' is a normal window, or 'FULLSCREEN' = display takes up whole screen (for displays of type 'frame' only) or 'ALWAYSONTOP' = the display remains on top, even when other windows are activated). Note that you must use the /Apply option if you want the fullscreen mode to take effect.

/Layout|layout

Recalculate dialog window size; include (L) or ignore (l) hidden controls (case sensitive!)

/Modal=itemId

Assign a modal parent to the display display. The modal parent itemId is inactive whilst the display exists and behind the display in the z-order.

SET display TITLE mode font color [ title ]

Set and configure the display's title. The option /Settitle can be used to set a new title without applying the other settings.
