public class ResizableGridRowLayout
extends GridRowLayout
ResizableGridRowLayout works with HeaderLayout to implement column resizing semantics for CompositeTable UIs.

Use a ResizableGridRowLayout when you have used a ResizableGridHeaderLayout on the Header object. ResizableGridRowLayout gets all of its layout settings from the ResizableGridHeaderLayout object, so there is no need to set any additional layout information on the ResizableGridRowLayout itself.

  • Constructor Details

    • ResizableGridRowLayout

      public ResizableGridRowLayout()
      Constructor ResizableGridRowLayout. Create a ResizableGridRowLayout object. Since a ResizableGridRowLayout object will automatically find the associated HeaderLayout, no properties need to be set on a ResizableGridRowLayout.

  • Method Details

    • computeSize

      protected org.eclipse.swt.graphics.Point computeSize​(org.eclipse.swt.widgets.Composite composite, int wHint, int hHint, boolean flushCache)
      Overrides:
      computeSize in class AbstractGridRowLayout

    • layout

      protected void layout​(org.eclipse.swt.widgets.Composite composite, boolean flushCache)
      Overrides:
      layout in class AbstractGridRowLayout

    • getWeights

      public int[] getWeights()
      Description copied from class: AbstractGridRowLayout
      Method getWeights. If isFittingHorizontally, returns an array representing the percentage of the total width each column is allocated or null if no weights have been specified.

      If !isFittingHorizontally, returns an array where each element is the minimum width in pixels of the corresponding column.

      Overrides:
      getWeights in class AbstractGridRowLayout
      Returns:
      the current weights array or null if no weights have been specified.

    • setWeights

      public AbstractGridRowLayout setWeights​(int[] weights)
      Description copied from class: AbstractGridRowLayout
      Method setWeights. If isFittingHorizontally, specifies an array representing the percentage of the total width each column is allocated or null if no weights have been specified.

      If !isFittingHorizontally, specifies an array where each element is the minimum width in pixels of the corresponding column.

      This property is ignored if the programmer has set a layout manager on the header and/or the row prototype objects.

      The number of elements in the array must match the number of columns and if isFittingHorizontally, the sum of all elements must equal 100. If either of these constraints is not true, this property will be ignored and all columns will be created equal in width.

      Overrides:
      setWeights in class AbstractGridRowLayout
      Parameters:
      weights - the weights to use if the CompositeTable is automatically laying out controls.
      Returns:
      this

    • getSumOfAllWeights

      public int getSumOfAllWeights()
      Description copied from class: AbstractGridRowLayout
      Returns the sum of all the weights in the weights property
      Overrides:
      getSumOfAllWeights in class AbstractGridRowLayout
      Returns:
      the sum of all the weights in the weights property

    • isFittingHorizontally

      public boolean isFittingHorizontally()
      Description copied from class: AbstractGridRowLayout
      Method isFittingHorizontally. Returns if the CompositeTable control will scale the widths of all columns so that they all fit into the available space. The default value is false.
      Overrides:
      isFittingHorizontally in class AbstractGridRowLayout
      Returns:
      Returns true if the table's actual width is set to equal the visible width; false otherwise.

    • setFittingHorizontally

      public AbstractGridRowLayout setFittingHorizontally​(boolean fittingHorizontally)
      Description copied from class: AbstractGridRowLayout
      Method setFittingHorizontally. Sets if the CompositeTable control will scale the widths of all columns so that they all fit into the available space. The default value is false.
      Overrides:
      setFittingHorizontally in class AbstractGridRowLayout
      Parameters:
      fittingHorizontally - true if the table's actual width is set to equal the visible width; false otherwise.
      Returns:
      this

    • getColumnAt

      protected org.eclipse.swt.widgets.Widget getColumnAt​(org.eclipse.swt.widgets.Composite rowOrHeader, int offset)
      Description copied from class: AbstractGridRowLayout
      Return the SWT Widget representing the specified column.
      Overrides:
      getColumnAt in class GridRowLayout
      Parameters:
      rowOrHeader - The header or row object
      offset - The column's offset.
      Returns:
      The SWT Widget.
