ArcEngine实现pagelayout中文本元素的属性对话框

1. 
2. 效果如上图，有点难看

 

源码如下

public partial class Properties : Form
    {
        IPageLayoutControlDefault pPageLayout = null;
        ITextElement pTextElement = null;
        ITextSymbol pTextSymbol = null;
        ICharacterOrientation pCharacterOrientation = null;
        IGraphicsContainer pGraphicsContainer = null;

        public Properties(IPageLayoutControlDefault pageLayout,ITextElement textElement)
        {
            InitializeComponent();
            pPageLayout = pageLayout;
            pTextElement = textElement;
            pTextSymbol = pTextElement.Symbol;
            pGraphicsContainer = pageLayout.ActiveView.GraphicsContainer;
        }

        private void Properties_Load(object sender, EventArgs e)
        {
            textBox1.Text = pTextElement.Text;
            textBox2.Text = pTextSymbol.Font.Name + "  " + pTextSymbol.Font.Size.ToString();
            numericUpDown1.Value = (decimal)(pTextSymbol.Angle);
            checkB.Checked = pTextSymbol.Font.Bold;
            checkU.Checked = pTextSymbol.Font.Underline;
            checkI.Checked = pTextSymbol.Font.Italic;

            pCharacterOrientation = pTextSymbol as ICharacterOrientation;
            checkO.Checked = pCharacterOrientation.CJKCharactersRotation;
        }

        private void buttonChange_Click(object sender, EventArgs e)     //更改字体
        {
            FontDialog fontDialog = new FontDialog();
            if (fontDialog.ShowDialog() == DialogResult.OK)
            {
                Font selectFont = fontDialog.Font;
                textBox2.Text = selectFont.Name + "  " + selectFont.Size.ToString();
                stdole.IFontDisp pFont = ESRI.ArcGIS.ADF.COMSupport.OLE.GetIFontDispFromFont(selectFont) as stdole.IFontDisp;

                pTextSymbol.Font = pFont;
            }
        }

        private void buttonOK_Click(object sender, EventArgs e)     //确定
        {
            pCharacterOrientation = pTextSymbol as ICharacterOrientation;
            pCharacterOrientation.CJKCharactersRotation = checkO.Checked;

            stdole.IFontDisp pFont = pTextSymbol.Font;
            pFont.Bold = checkB.Checked;
            pFont.Underline = checkU.Checked;
            pFont.Italic = checkI.Checked;
            pTextSymbol.Font = pFont;

            pTextElement.Text = textBox1.Text;
            pTextElement.Symbol = pTextSymbol;
            pGraphicsContainer.UpdateElement(pTextElement as IElement);
            pPageLayout.ActiveView.PartialRefresh(esriViewDrawPhase.esriViewGraphics, null, null);
            this.Close();
            this.Dispose();
        }

        private void buttonCancel_Click(object sender, EventArgs e)     //取消
        {
            this.Close();
            this.Dispose();
           
        }

      

    }

 

使用时要在主界面中的Pagelayout空间中编写双击事件，如下

 

private void axPageLayoutControl1_OnDoubleClick(object sender, IPageLayoutControlEvents_OnDoubleClickEvent e)
        {
            IElement pelement, selectElement = null;

            IGraphicsContainerSelect pGraphicsContainerSelect = pPageLayout.PageLayout as IGraphicsContainerSelect;
            IGraphicsContainer pGraphicsContainer = pPageLayout.PageLayout as IGraphicsContainer;
            pGraphicsContainer.Reset();
            pelement = pGraphicsContainer.Next();
           
            while (pelement != null)
            {
                if (pelement.HitTest(e.pageX, e.pageY, 0.1))
                {
                    if (pelement is ITextElement)
                    {
                        selectElement = pelement;
                    }

                }

                pelement = pGraphicsContainer.Next();
            }

            if (selectElement is ITextElement)
            {
                Properties propertiesForm = new Properties(pPageLayout, selectElement as ITextElement);
                propertiesForm.Visible = true;
            }

        }

 

没有做文本元素位置选择的功能，感觉那个作用作用不大，因为位置可以通过Select Element工具调整
