我已经试过下面的代码。
if(id==CHARTEVENT_OBJECT_DRAG && sparam=="#"+IntegerToString(OrderTicket())+"-TP") { // here was my functions }
我尝试在拖动完成后，用下面的代码将OBJPROP_SELECTED 设为 "假"，但没有效果。
请问我该如何解决？
{
SL_TPdrags();
Sleep(1000);
drag_onoff=false; // OBJPROP_SELECTED
}
先谢谢你。
对不起，我从未使用过CHARTEVENT_OBJECT_DRAG。
最后，我发现了 "OBJ_RECTANGLE 和OBJ_TEXT"，我想我可以用它们来代替 "OBJ_LABEL和OBJ_RECTANGLE_LABEL"，因为它们都是一起移动标线的。
问：那么，请问哪些对象对一起移动Bid线非常有用？
我真的很需要有价值的评论。
祝你周末愉快。

你说的一起移动是什么意思？
我尝试在拖动完成后，用下面的代码将OBJPROP_SELECTED 设为 "假"，但没有效果。

{
SL_TPdrags();
Sleep(1000);
drag_onoff=false; // OBJPROP_SELECTED

谢谢。
除非你在进一步测试sparam，否则该代码在 任何 对象被拖动。
我的原始代码。
{
if(id==CHARTEVENT_OBJECT_DRAG && sparam=="line") // the chart event of dragging the line
我已经知道/读过你的一个伟大的例子CrossHair.mq4。
但我在给Label、RectLabel对象提供Bid价格时感到很困难。也就是我想把Label, RectLabel对象和Bid线一起移动。
我只需要类似的图片，请找到附件文件。
祝您一切顺利。
对于固定尺寸的对象。OBJ_BUTTON,OBJ_RECTANGLE_LABEL 和 OBJ_EDIT, 属性 OBJPROP_XDISTANCE 和 OBJPROP_YDISTANCE 设置对象的左上角相对于图表角（OBJPROP_CORNER）的位置，X 和 Y 坐标将从这里开始计算，单位为像素。

这不是对我的回应。

但我使用的是下面的代码，我对你的代码做了一点改动--它对我来说完美无缺，是我想要的。到目前为止，我还没有遇到任何问题。
我是否做错了，请问？
一切都是最好的。
