A user-assigned numeric identifier for the form within a display.
An integer (0 to 999)
If no number is assigned, 0 is used.
FormNum can be used in an application program to identify the form that had focus when control returned to the program. (See $FormNum, and $MouseFormNum in the Language Reference.)
FNum, MenuNum, WNum
The vertical dimension (height) of the object, expressed in twips.
A number (longint)
In Displays, indicates the overall height of the display.
In FormFields, indicates the visual height of the field.
In Forms, indicates the overall height of the form.
In Windows, indicates the height of the window, including its non-client area.
It is required when either Hght (character rows) or WdgHght (twips) must be specified
Hght
The horizontal dimension (width) of the object, expressed in twips.
A non-negative number (longint)
In Displays, indicates the overall width of the display.
In FormFields, indicates the visual width of the field.
In Forms, indicates the overall width of the form.
In Windows, indicates the width of the window, including its non-client area.
It is required when either Wdth (character rows) or WdgWdth (twips) must be specified.
WdgHght, Wdth
Horizontal margin of an object. The left and right margins of the object, expressed in twips.
A number (longint)
Indicates the width of the interior unusable space from the left and right edges of the rectangle occupied by the object. For DisplayForms objects, this refers to the form object identified by the DisplayForms entry.
WdgHMargin is set to 0 if both HMargin (character columns) and WdgHMargin (twips) are $Null.
HMargin, VMargin, WdgVMargin
Vertical margin of an object. The top and bottom margins of the object, expressed in twips.
A non-negative number (longint)
Indicates the unusable space immediately below the top edge and immediately above the bottom edge of the rectangle occupied by the object. For DisplayForms objects, this refers to the form object identified by the DisplayForms entry.
WdgVMargin is set to 0 if both VMargin (character rows) and WdgVMargin (twips) are $Null.
HMargin, VMargin, WdgHMargin
The form’s sequence number in a display. A user-assigned number that can be used to control the tabbing sequence within the forms of a display.
An integer (0 to 999).
If FSN is set to 0, the software automatically resets it to match the Z-order (WdgZOrder) specified for the form. Accordingly, if all forms in a display are painted with FSNs of 0, then the Painter’s structure diagram automatically defines the tab order when WINDOW SET TABORDER BY TABINDEX is in effect. (BY TABINDEX is the default setting for graphic-class windows.)
FFSN, FormNum, WdgZOrder
Layer position of an object. When two objects overlap, WdgZOrder specifies the order in which they are “layered”. The object with the higher or highest number is on “top”.
An integer
The Structure Chart of the Screen Painter displays the relative Z-order of all objects in the form or display.
The Z-order of an object can be changed by dragging the object from its current position in the structure to a new position and releasing it.
FObjects closer to the bottom of the Structure Chart are displayed on top of objects closer to the top of the Chart.
A user-defined symbol that identifies an object involved in a user interface event.
A character string, up to 18 characters long
When a user interface event occurs, the WdgTag values for the objects involved are assigned to special system variables (Event.EventTag, Event.FieldTag, Event.MenuItemTag). This information identifies the objects involved in the event. The application program can then translate events into the desired action.
WdgTag defaults to the name of the object.
A user-assigned classification for a document.
Up to 18 alphanumeric characters
The name assigned to a document.
An 18-character string, containing a valid object name
