Programmer Guide/Shell Items/Display/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 [.. hNrows]

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.

hX

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 item1item2 …
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.

itemX

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

The string itemX is an asterisk - a menu separator is added rather than a caption.

The string itemX begins with the character '>' (e.g. >text) - A submenu is defined using text as the caption.

The string itemX 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 itemX 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.
