public final class LayoutUtil extends Object
A utility class that has only static helper methods.

  • Field Details

    • INF

      public static final int INF
      A substitute value for aa really large value. Integer.MAX_VALUE is not used since that means a lot of defensive code for potential overflow must exist in many places. This value is large enough for being unreasonable yet it is hard to overflow.

  • Method Details

    • getVersion

      public static String getVersion()

      Returns the current version of MiG Layout.

      Returns

      The current version of MiG Layout. E.g. "3.6.3" or "4.0"

    • getGlobalDebugMillis

      public static int getGlobalDebugMillis()

      If global debug should be on or off. If > 0 then debug is turned on for all MigLayout instances.

      Returns

      The current debug milliseconds.

      • LC#setDebugMillis(int)

    • setGlobalDebugMillis

      public static void setGlobalDebugMillis(int millis)

      If global debug should be on or off. If > 0 then debug is turned on for all MigLayout instances.

      Note! This is a passive value and will be read by panels when the needed, which is normally when they repaint/layout.

      Parameters
      • millis: @param millis The new debug milliseconds. 0 turns of global debug and leaves debug up to every individual panel.

      • LC#setDebugMillis(int)

    • setDesignTime

      public static void setDesignTime(ContainerWrapper cw, boolean b)

      Sets if design time is turned on for a Container in ContainerWrapper.

      Parameters
      • cw: @param cw The container to set design time for. null is legal and can be used as a key to turn on/off design time "in general". Note though that design time "in general" is always on as long as there is at least one ContainerWrapper with design time.

      If this method has not ever been called it will default to what Beans.isDesignTime() returns. This means that if you call this method you indicate that you will take responsibility for the design time value.

      • b: true means design time on.

    • isDesignTime

      public static boolean isDesignTime(ContainerWrapper cw)

      Returns if design time is turned on for a Container in ContainerWrapper.

      Parameters
      • cw: @param cw The container to set design time for. null is legal will return true if there is at least one ContainerWrapper (or null) that have design time turned on.
      Returns

      If design time is set for cw.

    • getDesignTimeEmptySize

      public static int getDesignTimeEmptySize()

      The size of an empty row or columns in a grid during design time.

      Returns

      The number of pixels. Default is 15.

    • setDesignTimeEmptySize

      public static void setDesignTimeEmptySize(int pixels)

      The size of an empty row or columns in a grid during design time.

      Parameters
      • pixels: @param pixels The number of pixels. Default is 0 (it was 15 prior to v3.7.2, but since that meant different behaviour under design time by default it was changed to be 0, same as non-design time). IDE vendors can still set it to 15 to get the old behaviour.

    • getSizeSafe

      public static int getSizeSafe(int[] sizes, int sizeType)

    • isLeftToRight

      public static boolean isLeftToRight(LC lc, ContainerWrapper container)

      Returns if left-to-right orientation is used. If not set explicitly in the layout constraints the Locale of the parent is used.

      Parameters

      • lc: The constraint if there is one. Can be null.

      • container: The parent that may be used to get the left-to-right if ffc does not specify this.

      Returns

      If left-to-right orientation is currently used.

    • setSerializedObject

      public static void setSerializedObject(Object caller, Object o)

      Sets the serialized object and associates it with caller.

      Parameters

      • caller: The object created o

      • o: The just serialized object.

    • getSerializedObject

      public static Object getSerializedObject(Object caller)

      Returns the serialized object that are associated with caller. It also removes it from the list.

      Parameters
      • caller: The original creator of the object.
      Returns

      The object.
