Class IDEUtil

java.lang.Object
net.miginfocom.layout.IDEUtil

public class IDEUtil extends Object
This class contains static methods to be used by IDE vendors to convert to and from String/API constraints.

Note that LayoutUtil.setDesignTime(ContainerWrapper, boolean) should be set to true for this class' methods to work.

  • Constructor Details

    • IDEUtil

      public IDEUtil()
  • Method Details

    • getIDEUtilVersion

      public String getIDEUtilVersion()
      Returns the version of IDEUtil
      Returns:
      The version.
    • getGridPositions

      public static HashMap<Object,int[]> getGridPositions(Object parentContainer)
      Returns the grid cells that the components in parentContainer has.
      Parameters:
      parentContainer - The parent container. It is an object since MigLayout is GUI toolkit independent.
      Returns:
      A new hashmap with the components mapped to an array [x, y, spanx, spany].

      Dock components will always have x and y less than -30000 or more than 30000. This is since they are actually part of the grid, but on the outer edges.

      Components that span the "rest of the row/column" have really large span values. Actually 30000-x or 30000-y.

      Generally, the grid does not need to have the upper left at 0, 0. Though it normally does if you don't set the cells explicitly to other values. Rows and columns that are completely empty and that does not have an explicit row/column constraint will be totally disregarded.

    • getRowSizes

      public static int[][] getRowSizes(Object parentContainer)
      Returns the sizes of the rows and gaps for a container. There will be two arrays returned [0] and [1].

      The first array will be the indexes of the rows where indexes that are less than 30000 or larger than 30000 is docking rows. There might be extra docking rows that aren't visible but they always have size 0. Non docking indexes will probably always be 0, 1, 2, 3, etc..

      The second array is the sizes of the form:
      [left inset][row size 1][gap 1][row size 2][gap 2][row size n][right inset].

      The returned sizes will be the ones calculated in the last layout cycle.

      Parameters:
      parentContainer - The container to return the row sizes and gaps for. In Swing it will be a Container and in SWT it will be a org.eclipse.swt.widgets.Composite.
      Returns:
      The sizes or null if LayoutUtil.isDesignTime(ContainerWrapper) is false or parentContainer does not have a MigLayout layout manager. The returned sizes will be the ones calculated in the last layout cycle.

    • getColumnSizes

      public static int[][] getColumnSizes(Object parentContainer)
      Returns the sizes of the columns and gaps for a container. There will be two arrays returned [0] and [1].

      The first array will be the indexes of the columns where indexes that are less than 30000 or larger than 30000 is docking columns. There might be extra docking columns that aren't visible but they always have size 0. Non docking indexes will probably always be 0, 1, 2, 3, etc..

      The second array is the sizes of the form:
      [top inset][column size 1][gap 1][column size 2][gap 2][column size n][bottom inset].

      The returned sizes will be the ones calculated in the last layout cycle.

      Parameters:
      parentContainer - The container to return the column sizes and gaps for. In Swing it will be a Container and in SWT it will be a org.eclipse.swt.widgets.Composite.
      Returns:
      The sizes and indexes or null if LayoutUtil.isDesignTime(ContainerWrapper) is false or parentContainer does not have a MigLayout layout manager. The returned sizes will be the ones calculated in the last layout cycle.

      isCols - The the constraint should be returned for columns rather than rows.
      Returns:

      Adds the a constraint string that can be re-parsed to be the exact same DimConstraint.
      Parameters:
      dc - The layout constraint to return as a constraint string.

    • addComponentDimConstraintString

      private static void addComponentDimConstraintString(DimConstraint dc, StringBuffer sb, boolean asAPI, boolean isHor, boolean noGrowAdd)
      Returns the a constraint string that can be re-parsed to be the exact same DimConstraint.
      Parameters:
