Class MViewParams

java.lang.Object
  chemaxon.marvin.beans.MViewParams

public class MViewParams
extends java.lang.Object

MViewParams is a helper tool to generate parameter string to MViewPane.
Note that only molecules and labels are supported yet, buttons and images are not.
Example of typical usage:

      MViewParams mvpw = new MViewParams();
      mvpw.setRowCount(rows);
      mvpw.setColumnCount(cols);
      mvpw.setVisibleRows(actualVisibleRows);
      mvpw.setHeaderCellSize(2, 1);
      mvpw.addMolecule(1, 0, 1, 1, GridBagConstraints.CENTER,
              GridBagConstraints.BOTH, 1, 1);
      mvpw.addLabel(0, 0, 1, 1, GridBagConstraints.CENTER,
              GridBagConstraints.NONE, 0, 1);
      mvpw.setMoleculeCellSize(200, 200);
      mvpw.setLabelProperty(10, true, false);
      viewPane.setParams(mvpw.getMViewParam());

This equals with the following parameter setting:

      String layout = (size > 1)?
              ("layout0=:2:1:M:1:0:1:1:c:b:1:1:L:0:0:1:1:c:n:0:1\n" +
              "param0=:M:200:200:L:10b\n") : "";
      viewPane.setParams(
          "rows="+rows+"\n"+
          "cols="+cols+"\n"+
          "visibleRows="+actualVisibleRows+"\n"+
           layout +
          "\n");

Constructor Detail

MViewParams

public MViewParams()

For each new parameter generation a new MViewParams instance is necessary to be created.

Method Detail

getMViewParam

public java.lang.String getMViewParam()

Generates the parameter string that can be set to MViewPane.

Returns:

parameters as correcty formatted string

setRowCount

public void setRowCount(int i)

Sets the total nuber of rows.

Parameters:

i - maximum number of rows

setColumnCount

public void setColumnCount(int i)

Sets the nuber of columns. This equals with the number of visible columns.

Parameters:

i - number of rows

setVisibleRows

public void setVisibleRows(int i)

Sets the nuber of visible rows. If this is less then the total number of rows, then a srollpane is available.

Parameters:

i - number of visible rows less or equal than the total number of rows

setHeaderCellSize

public void setHeaderCellSize(int row,
                              int column)

Sets a logical cell extent by interpreting rows and columns as part of a sub-table. For example when having labels in odd rows and molecules in even rows the cell size should be declared with 2 rows and 1 column to be handled properly at scrolling.

Parameters:

row - number of rows in the sub-table

column - number of columns in the sub-table

addLabel

public void addLabel(int startRow,
                     int startColumn,
                     int rows,
                     int columns)

Defines a label component inside the MarvinView table.

Parameters:

startRow - uppermost row of the label

startColumn - leftmost column of the label

rows - number of rows to occupy

columns - number of columns to occupy

addMolecule

public void addMolecule(int startRow,
                        int startColumn,
                        int rows,
                        int columns)

Defines a molecule viewer component inside the MarvinView table.

Parameters:

startRow - uppermost row of the viewer

startColumn - leftmost column of the viewer

rows - number of rows to occupy

columns - number of columns to occupy

addLabel

public void addLabel(int startRow,
                     int startColumn,

                     int columns,
                     int anchor,
                     int fill,
                     int weightx,
