"></applet>

1.1   Applet only parameters

ParameterMeaning
mol The URL of the molecule file or the file itself (inline) in MDL mol, compressed mol, SMILES or SMARTS format.
If you specify the molfile inline in an HTML file (as an applet parameter), then you must end all lines with "\" (backslash). The file format and/or import options can be specified if one of the following forms is used:
"file{options}",
"file{MULTISET,options}",
"file{format:}",
"file{format:options}", or
"file{format:MULTISET,options}".
If the MULTISET option is specified, then a multi-molecule file is read into one molecule object containing multiple atom sets.
Examples: "foo.xyz{f1.4C4}", "foo.xyz.gz{gzip:xyz:MULTISET,f1.4C4}"
preload Comma-separated list of external modules to preload. External modules are class files in the chemaxon/marvin/modules directory.
moduleargument of getM() call that requires it
MolExport "mol", "csmol"
SmilesExport "smiles"
CmlExport "cml"
Parity "mol", "smiles" (but not "smiles:0")
PdbExport "pdb"
PovExport "pov"
SybylExport "sybyl"
XYZExport "xyz"
Note. Preloading is required if you call getM from JavaScript in a buggy browser/JVM combination. Without preloading, getM might freeze Netscape 6 (Sun Java 1.3) and Netscape 3 would also fail because these browsers cannot call network functions from JavaScript.
cacheMols Store loaded molecules in an internal cache (true or false).
loadMols Comma-separated list of molfiles to preload. Useful for caching molecules in JavaScript "slideshows".
molChanged0
molChanged1
molChanged2
...
Evaluates a JavaScript code when the molecule is loaded or changed in the specified cell. The number in the parameter name determines the cell index. If no molecule table, use molChanged0 to refer to the molecule. The parameter value should be a JavaScript code. E.g.:
    <param name="molChanged0" value="alert('First molecule is modified')">
    
skin Change the component's Look & Feel (only in SWING applet). If you do not specify this parameter, Marvin will use the default LookAndFeel style.
This parameter value is the name of the new LookAndFeel class.
javax.swing.plaf
.metal
.MetalLookAndFeel

1.2   3D and animation

ParameterMeaningDefault
rendering Rendering style.
  • wireframe - wireframe
  • wireknobs - wireframe with knobs
  • sticks - 3D sticks
  • ballstick - ball & stick
  • spacefill - balls
wireframe
wireThickness line thickness for "wireframe" and "wireknobs" rendering modes, in Angstroms. 0.064
stickThickness 3D stick diameter for "sticks" and "ballstick" rendering modes, in Angstroms. 0.1
ballRadius Ball radius for "ballstick" rendering mode, in units of covalent radius. 0.5
animate Start an XYZ animation sequence, or starts rotating the specified 3D molecule(s).
Possible values: off, all, or a comma-separated list of molecule indices (0...n-1).
Note: This parameter does not apply to beans, only to applet.
off
animFPS Number of frames per second in 3D animation. 10
animDelay Delay (seconds) before repeating the animation. 0
animSync Whether the animations in different cells should be synchronized. false
spin
spin0
spin1
spin2
...
Spinning rate and axis for animated molecules. Spinning rate is specified in degrees per second, the axis is specified with a 3D vector. Numbers are separated by commas.
Note: XYZ animations do not spin by default, only if this parameter is set.
36,0,1,0
script
script0
script1
script2
...
Script containing a subset of RasMol commands delimited by semicolons. If this applet parameter is specified, then the mol parameter is neglected. The molecule(s) must be loaded using the load command in the script.
Note: To load the script from a file, use the script command:
<param NAME="script" VALUE="script myscript.spt">
 

1.3   Molecule tables

rows Number of "molecule rows", including the optional header row.
cols Number of "molecule columns".
visibleRows Number of visible rows. The table is scrollable if less than rows. Default value: visibleRows = rows.
visibleCols Number of visible columns. The table is scrollable if less than cols. Default value: visibleCols = cols.
layout Layout of molecule, label, button and checkbox components in a cell.
layoutH Layout for the header row.
param Parameters of the components.
paramH Parameters for the header row.
cell0
cell1
cell2
...
Contents of the cells.
Use these instead of the mol parameter.
border Border width in pixels. Default: 0 (no border between cells).
Increases the total applet WIDTH by border*(cols-1), and the HEIGHT by border*(rows-1).

1.3.1   layout

The layout and layoutH parameters are in the following format: ":rows:cols:type:k:l:h:w:anchor:fill:[weighty:[weightx:]]type:k:l:...", where : is the field separator, rows is the number of rows in the cell, cols is the number of columns, type is the type of the component in row k, column l of the current cell, h is the height of the component (rows), w is the width (columns).
The anchor parameter determines where to place the component if its size is smaller than its display area. It the component size is larger than the size of its text label, then anchor also sets the label alignment. Possible values: c (center), n (north), s (south), e (east), w (west), ne (northeast), etc.
The fill parameter determines how to resize the component if its size is smaller then its display area. Possible values: n (none), h (horizontal), v (vertical) or b (both).
The weights are nonnegative integers, zero by default. They determine how to distribute space. If all the weights are zero, all the components clump together in the center of the applet.

If you are familiar with Java, you might have noticed that anchor, fill, weightx and weighty have the same names as the fields of the GridBagConstraints class. The reason is that MarvinView uses the GridBagLayout class to determine the places and sizes of the components.

Component types: M (molecule), L (label), B (button), C (checkbox), T (text field) and I (image).

Example:

<param NAME=layout VALUE=":4:3:
M:0:0:4:1:c:n:
L:0:2:1:1:c:n:0:10:
L:1:2:1:1:c:n:0:10:
C:0:1:1:1:c:n:
C:1:1:1:1:c:n:
C:2:1:1:1:c:n:
B:3:1:1:1:c:n:10">

1.3.2   param

In a param or paramH parameter, the first character is the field separator (`:' here). The first field is the type of the first component (M, L, B, C or T), followed by its n parameters in the forthcoming n fields. Then the same for the second component, etc. Component parameters:
:M:width:height width and height are in pixel units.
:L:fontprops fontprops: font properties.
:B:fontprops::
:B:fontprops:description:
:B:fontprops:description:frame
fontprops: font properties,
description: description string,
target: target frame.
:C:fontprops:
:C:fontprops:description
fontprops: font properties,
description: description string.
You may specify the checkbox group number in the type field, by writing gn next to the type-specifying character C, where n is the group number. No more than one button in a group can be pressed at the same time.
:T:fontprops
:T:fontprops:columns
:T:fontprops:columns:editable
fontprops: font properties,
columns: number of columns,
editable: editable (rw) or read only (r).
The fontprops field usually contains only one number, the font size. Additional properties are "b" (bold font) and "i" (italic). A 12pt bold italic font is specified as "12bi".

Example:

<param NAME=param VALUE=":
M:100:100:
L:10b:
C:10:select this molecule:
Cg0:10:include this structure:
B:10:search for more molecules like this:_self:
T:10:
T:10:15:
T:10:15:rw">

1.3.3   celli

In a celli parameter, the first character is the field separator (`|' here). The fields contain the component parameters in order.

ComponentParametersDescription
M |molfile molfile: the molecule URL or the molecule itself (inline) in MDL mol or compressed mol format.
L |label label: the label string.
B |label|spec|action label: the button label,
spec: the special character (% from now),
action: the action string.
C |||||
|||state||
|||state|-|-
...
|label0|label1|state|action0|action1
label0: label for the unchecked state,
label1: label for the checked state,
state: default state (0, 1 or nothing),
action0: action string for unchecking,
action1: action string for checking.
For a "real" checkbox, both labels have to be empty string, otherwise the "checkbox" will be buttonlike.
If both action strings are empty, then the checkbox is disabled. To make it enabled without specifying JavaScript actions, the action values must be "-". Example: "|||1|-|-"
T |
|string
string: initial value.
I |iconfile||
|iconfile|action|title
iconfile: GIF or JPEG file containing the icon,
action: image file or js:JavaScript code
title: window title, only used if action is an image file.

The action string can be an URL for buttons, a JPEG, PNG or GIF file for images, or js:javascript expression for buttons, checkboxes and images. The button action string may contain %C (where % is the special character), which is substituted with the checkbox states represented as a hexadecimal number. The nth bit in this number is the state of the nth checkbox.

A javascript expression can be used only if you specify the MAYSCRIPT attribute in the applet tag.

Example:

<param NAME=cell2 VALUE="|\
  MSketch 04169816382D\\ 66 72  0  0  0  0  0  0  0  0999 V2000\mcIWFRwV60\
