创建一个firemonkey组件 [英] creating a firemonkey component

问题描述

我正在Delphi XE4中使用Firemonkey，我无法使用菜单项Component - > New Component创建一个新的组件。
组件是VCL还是Firemonkey组件，还是首先创建一个包，结果是一样的。
Delphi中的工具调色板似乎被搜索，并逐渐关闭，当它选择一个祖先组件时，它将空白组件和一个组件对话框，其中显示无可用项目。

I'm working with Firemonkey in Delphi XE4 and I'm unable to create a new component using the menu item Component -> New Component. Whether the component is a VCL or Firemonkey component or whether I create a package first the result is the same. The Tool Palette in Delphi appears to be searched and gradually it closes leaving it empty of components and a component dialog box that says "No Items available" when it comes to selecting an ancestor component.

我有两个独立的Delphi XE4安装，同样的症状出现在两者上。
Delphi认为没有合适的基础组件来构建新的组件。

I have two separate installations of Delphi XE4 and the same symptoms appear on both. It appears that Delphi believes that there are no suitable base components on which to build a new component.

推荐答案

创建组件在代码中相当简单。

Creating components is fairly straightforward in code.

• 创建一个单元。


• 为您的组件添加代码。



• 添加注册程序。

• Create a unit.
• Add code for your component.

• Add a Register procedure.

procedure Register;
begin
  RegisterComponents('NewPage', [TMyComponent]);
end;

在实现部分添加注册声明。

Add a declaration for Register in the implements section.

在初始化部分添加对RegisterFMXClasses的调用。

Add a call to RegisterFMXClasses in your initialization section.

implementation
uses FMX.Types;
...
initialization
  RegisterFMXClasses([TMyComponent]);
end.

创建一个包。

Create a package.

（注意：测试时通常最好在运行时创建您的组件，一旦它相当稳定，您只需要做包装）。

(Note: It's usually best to create your component at run time whilst testing. You only need to do the package stuff once it's fairly stable).
