问:
是否存在文档的全局/默认文本高度用户想要输入高度值时,它无法被用户创建此vdtext时的当前vdtext改变,用户如何才能在cmdText启动之前设置文本的高度/p>
答:
此项功能是存在的,想要达到此效果,请参阅以下代码:
private void button3_Click(object sender, EventArgs e) { vdDocument doc = vdFramedControl1.BaseControl.ActiveDocument; doc.New(); cmdTextWithHeight(doc, null, null, null, 5.0); cmdTextWithHeight(doc, "VDF version6", new gPoint(30,30), null, 15.0); cmdTextWithHeight(doc, null, new gPoint(10,10), 0.0d, 25.0); cmdTextWithHeight(doc, "hi", null, 30.0, 35.0); } private bool cmdTextWithHeight(vdDocument document, object TextString, object InsertionPoint, object RotationAngle, double TextHeight) { bool ret = false; double oldheight = document.ActiveTextStyle.Height; // store the old value to set this back after this finishes document.ActiveTextStyle.Height = TextHeight;// set the Height that is needed to activetextstyle if (document.CommandAction.CmdText(TextString, InsertionPoint, RotationAngle)) { vdText txt = document.ActiveLayOut.Entities[document.ActiveLayOut.Entities.Count - 1] as vdText; // get the text that was just created if (txt != null) { //... do other things there with the just-created-vdText if you like !! txt.Height = TextHeight; // see it to the Height so evene if activeTextStyle changes this remains. ret = true; } } document.ActiveTextStyle.Height = oldheight; // set the original value back. return ret; }
