我正在分析我的客户提出的问题。我们有一个 JFrame，里面有 6 个 JInternalFrames。如果任何一个 JInternalFrame 被最大化，并且如果我们从这个 JInternalFrame 打开另一个 JInternalFrame，那么新的 JInternalFrame 也将以最大化状态打开。同样，如果它处于恢复模式，则另一个 JInternalFrame 将在恢复模式下打开。我需要知道新打开的 JInternalFrame 如何确定父框架处于最大化或恢复模式。

感谢大家的考虑。

public Object openEditor(String p_editorClassName) {

Object editorObject = null;

try {

// is this window already open

editorObject = m_editorList.get(p_editorClassName);

boolean isNewEditor = editorObject == null;

if (isNewEditor)

{

   ++m_openFrameCount;editorObject = createNewEditor(p_editorClassName);

m_editorList.put(p_editorClassName, editorObject);

}

int defaultWidth = editorObject instanceof IEditor ? ((IEditor)editorObject).getDefaultEditorWidth() : IDEConstants.DEFAULT_EDITOR_WIDTH;

int defaultHeight = editorObject instanceof IEditor ? ((IEditor)editorObject).getDefaultEditorHeight() : IDEConstants.DEFAULT_EDITOR_HEIGHT;

        if (editorObject instanceof JInternalFrame)
        {
            JInternalFrame editorFrame = (JInternalFrame) editorObject;
            if (isNewEditor)
            {
                ((GenericEditor)editorFrame).setQFTestName(((JInternalFrame)editorObject).getTitle());
                editorFrame.setSize(defaultWidth, defaultHeight);
                editorFrame.setVisible(true);
                addFrameToDesktop(editorFrame);
                editorFrame.setLocation(XOFFSET * m_openFrameCount, YOFFSET * m_openFrameCount);

                if (editorObject instanceof GenericEditor)
                { 
                    DecimalFormat df = new DecimalFormat("00");
                    String strCount = df.format(m_editorList.size());
                    String editorKey = EditorsIDEState.PROP_EDITOR + strCount;
                    ((GenericEditor)editorObject).setState(getIDEState().getProps(), editorKey, p_editorClassName);
                }
            }
            else
            {
                // Need to undo minimize here, otherwise it will return null for getParent() and will
                // then re-add back into desktop below
                //
                if (editorFrame.isIcon())
                {
                    editorFrame.setIcon(false);
                }

                // Check to see if we have ever been added to the desktop
                //
                if (editorFrame.getParent() == null)
                {
                    addFrameToDesktop(editorFrame);
                }

                if (editorFrame.getWidth() < 1 && editorFrame.getHeight() < 1)
                {
                    // width and height is not visible, so set the size back to the original
                    editorFrame.setSize(defaultWidth, defaultHeight);
                }
                else if (editorFrame.getWidth() < 1)
                {
                    // width is not visible, so set the width back to the original
                    editorFrame.setSize(defaultWidth, editorFrame.getHeight());
                }
                else if (editorFrame.getHeight() < 1)
                {
                    // height is not visible, so set the height back to the original
                    editorFrame.setSize(editorFrame.getWidth(), defaultHeight);
                }

                // is this window still visible
                if (editorFrame.isClosed())
                {
                    // to reopen an JInternalFrame, re-attach to container
                    editorFrame.setVisible(true);
                    editorFrame.setClosed(false);
                    addFrameToDesktop(editorFrame);
                }
                if (!editorFrame.isVisible())
                {
                    editorFrame.setVisible(true);
                }
            }
            editorFrame.setSelected(true);
            editorFrame.moveToFront();
        }
    }
    catch (Exception e)
    {

        e.printStackTrace();
    }
    return editorObject;
}

在调试时我有 IsMaximum FALSE 直到倒数第二行，即 editorFrame.setSelected(true); 在此之后，我将 IsMaximum 设为 TRUE
