Clipboard Formats Configuration

Using this configuration it is possible to control the copy/paste operations available in the applet; the formats available for copy or paste can be manipulated, or the corresponding resources can be pre-loaded.

For example, the copy or paste of specific file formats can be forced to be immediately available after the start of the applet, so instead of loading the underlying architecture on demand, the required resources are loaded during the applet initialization time.

Also, the formats available on the clipboard after a simple copy operation can be configured, as well as the list of formats available in the Copy As dialog.

The configuration is available through a Java properties file which has to be placed to the APPLET_CODEBASE/chemaxon/marvin/datatransfer.properties file or MarvinSketch_installation_directory/chemaxon/marvin/datatransfer.properties file. If this file is available in the applet codebase, the configuration will take effect.

This .properties file contains settings for format keys. The property name format is as follows: formatkey.configuration.setting.id, so for example, if somebody wants to disable the PNG format on the Copy As dialog, then the png.use.dialog key has to be set to false.

Available Format Keys in the Property File, and the Corresponding Formats

Format key The corresponding format
mrv Marvin Document Format
skc IsisDraw Sketch file format
cdx ChemDraw Sketch file format
mol MDL MOLfile format
rxn MDL RXNfile format
smiles Daylight SMILES format
smarts Daylight SMARTS format
cxsmiles Chemaxon extended SMILES format
cxsmarts Chemaxon extended SMARTS format
name IUPAC name format
trad_name Traditional name format
inchi IUPAC InChI/RInChI format
inchikey IUPAC InChIKey/RInChIKey format
string Molecule source, containing the actual file format of the molecule object
emf Enhanced Metafile picture format (available only on Windows platforms)
jpg JPG image format
png PNG image format

Available Configurable Properties for All Formats and Their Meanings

Parameter name Valid values Meaning
name can be any String This will be displayed in the Copy As dialog to represent the format.
disabled true/false If set to false, then the format won't be available at all.
preload.copy true/false If set to true, then the classes needed for copying in the specified format will be preloaded at appletinitialization.
preload.paste true/false If set to true, then the classes needed for pasting in the specified format will be preloaded at appletinitialization.
preload true/false If set to true, then the classes needed for copying or pasting in the specified format will be preloaded at appletinitialization.
use.default true/false If set to true, then the molecule will be placed to the clipboard by a simple copy operation in the specifiedformat.
use.dialog true/false If set to false, then the specified format won't be available in the Copy As dialog.

By default, none of the formats are pre-loaded, all of them are configured as they worked before.

Other Available Options

The following keys are not related to the formats and should be used as they are.

Property name Valid values Meaning
ole.enabled true/false To disable the Microsoft OLE object copy, set this to false.
ole.name can be any String This will be displayed in the Copy As dialog to represent the Microsoft OLE object format.
separator a comma-separated list of format keys. After the enumerated formats a separator will be placed in the copy as dialog.

Further Format Couplings

Please consider this information also while changing the configuration.

  • If OLE is enabled, then the OLE data will contain the MRV, the MOL or RXN file, and the EMF image also.
  • The default copy places image data to the clipboard, in java image format. If you want to disable this behavior you have to set the jimage.use.default property to false.
