## 启动Delphi：准备安装新组件 **(** Starting Delphi: Preparing to Install a New Component **)** ##

![delphi project start][]

Zarko Gajic

扎尔科·加季奇(Zarko Gajic)

First, start Delphi. A new project is created by default... Close it by pointing to File - Close All.

首先，启动Delphi。 默认情况下会创建一个新项目...通过指向文件-全部关闭将其关闭。

## Delphi IDE菜单：组件-安装组件 **(** Delphi IDE Menu: Component - Install Component **)** ##

![install component delphi][]

Zarko Gajic

扎尔科·加季奇(Zarko Gajic)

Once the default new project is closed, select the "Install Component" menu item from the "Component" main Delphi IDE menu.

关闭默认的新项目后，从“组件”主Delphi IDE菜单中选择“安装组件”菜单项。

This will invoke the 'Install Component' dialog.

这将调用“安装组件”对话框。

## “安装组件”对话框 **(** "Install Component" Dialog Box **)** ##

![delphi install component browse][]

Zarko Gajic

扎尔科·加季奇(Zarko Gajic)

With the "Install Component" dialog active, select the file with the component's source (?.PAS). Use the Browse button to select the unit, or enter the name of the unit you want to install in the "Unit File Name" edit box.

在“安装组件”对话框处于活动状态的情况下，选择带有组件源(？.PAS)的文件。 使用浏览按钮选择单元，或在“单元文件名”编辑框中输入要安装的单元的名称。

Note 1: If the unit's folder is in the Search Path, a full path name is not required. If the folder containing the unit file is not in the Search Path, it will be added to the end.

注意1：如果设备的文件夹在搜索路径中，则不需要完整的路径名。 如果包含单位文件的文件夹不在搜索路径中，它将被添加到末尾。

Note 2: The "Search Path" edit box displays the path used by Delphi to search for files. Leave this as it is.

注意2：“搜索路径”编辑框显示Delphi用于搜索文件的路径。 保持原样。

## 选择Delphi软件包作为组件 **(** Select Delphi Package for the Component **)** ##

![select delphi package][]

Zarko Gajic

扎尔科·加季奇(Zarko Gajic)

Use the "Package file name" drop-down list to select the name of an existing package. Note: all Delphi components are installed in the IDE as packages.

使用“软件包文件名”下拉列表选择现有软件包的名称。 注意：所有Delphi组件都作为软件包安装在IDE中。

Note 1: The default package is "Borland User Components", there is no special need to alter this.

注1：默认程序包是“ Borland用户组件”，没有特别需要更改它。

Note 2: The screenshot shows that the package "ADP\_Components.dpk" is selected.

注2：屏幕快照显示已选择包“ ADP\_Components.dpk”。

With the component's unit and package selected, hit the "OK" button on the "Install Component" dialog box.

选择组件的单位和软件包后，单击“安装组件”对话框上的“确定”按钮。

## 确认添加新组件 **(** Confirm Adding a New Component **)** ##

![confirm adding new component delphi][]

Zarko Gajic

扎尔科·加季奇(Zarko Gajic)

With the component's unit and package selected, after you hit the "OK" button on the "Install Component" dialog box Delphi will prompt you whether you want to rebuild the modified package or not.

选中组件的单元和软件包后，在“安装组件”对话框中单击“确定”按钮后，Delphi将提示您是否要重建修改后的软件包。

Click on "Yes"

点击“是”

After the package is compiled, Delphi will show you a message saying that the new TColorButton (or whatever the component name is) component was registered and already available as part of the VCL.

编译软件包后，Delphi将向您显示一条消息，说明新的TColorButton(或任何组件名称)组件已注册，并且已作为VCL的一部分提供。

Close the package detail window, allowing Delphi to save the changes to it.

关闭软件包详细信息窗口，使Delphi可以将更改保存到该窗口。

## 使用已安装的组件 **(** Using the Installed Component **)** ##

![using installed component delphi][]

Zarko Gajic

扎尔科·加季奇(Zarko Gajic)

If all went well, the component is now available in the components palette.

如果一切顺利，该组件现在可以在组件面板中使用。

Drop the component on a form, and simply: use it.

将组件放在窗体上，然后简单地：使用它。

Note: if you have more units with components, just go back to Step 2: "Delphi IDE menu: Component - Install Component" and start from there.

注意：如果您有更多带有组件的单元，只需返回到步骤2：“ Delphi IDE菜单：组件-安装组件”，然后从那里开始。
