关于标记语言和构造函数的一般信息。

1.构造函数元素的属性值是预定义的。如果没有明确定义，则会为属性分配默认值。


2.元素的交互行为是预设的，但用户可以更改或禁用不同的响应。


3.3. 在计算组成组的位置和大小时，会自动计算界面窗口的大小。如果用户指定了右边距和下边距（边距），也会考虑在内。


4.某些元素的长度直接取决于文本的长度。如果用户没有设置明确的值，长度会自动计算。否则，构造函数会截断超出元素的文本，并用虚线保存用户的值。此类元素包括复选框、单选按钮、文本标签、水平和垂直制表符。


5.在构建窗口时，设计者会力求采用表格布局，并保持元素组的对称性。复选框或 类似类型的元素 会自动对齐到一个共同的长度值。


6.6. 设计者坚持使用表格布局，这使得界面的构建更加容易，而且为了提高灵活性，设计者使用标志和绑定将元素分成若干组，并进行排列。


7.7. 单个窗口中的元素数量不受限制。


8.单个项目中的窗口数量不受限制。


9.所有项目都必须有任务栏和上下文菜单。但是，如果您注释了文件中的 OPEN_ON_INIT (OOI) 命令，则可以禁用任务栏的显示。然后有必要禁用窗口最小化属性（存在这种可能性）。


10.在用户任务栏的右侧，用户可以设置按钮来调用自己的窗口。


11.当光标悬停时，所有项目都可以有一个带有名称的工具提示。为此，您需要在属性 _,SHOW_NAMETIP 中编写一条命令。


12.双击图表时，构造函数或用户的上下文菜单将显示。


13.在指定框架、颜色、字体、图标和声音时，构造函数的辅助窗口可以让您更轻松地查找和选择元素属性。


14.14. 在最新版本中编写代码时，需要先编译标记代码，然后再编译指标 KIB-source.mq5，否则会出现白屏和挂起的错误（在旧版本 2470 中没有此类问题）。


下面继续...

 
接下来，让我们研究一下构建组时的元素布局。
 

在窗口中定位组：



设置窗口右侧和底部的缩进：

0.


1.

2.




设置元素之间的间距

1.

2.


3.


5.


6.

延续元素布局的主题，按钮的一切都很清楚，因为它们有默认大小或由用户定义。但对于长度与文本长度挂钩的元素来说，一切都很模糊。下面是一些复选框和单选按钮的例子：

1. 复选框和单选按钮的名称几乎相同。


2. 一个单选按钮比其他按钮长很多。它们变得一样长：


3.在第二列中，中间的复选框明显较长。其他复选框的大小与之相同：


4.明确设置复选框和单选按钮的长度会自动缩短输出文本。
