Question

我在安装程序的MUI目录页面上使用Resource Hacker添加了自定义按钮，现在我想要在单击按钮时，然后用户输入InstallDir（安装应用程序的路径）的默认文本框，充满了一些指定的文字。请帮我解释一下代码？

我正在使用ButtonEvent插件，但我不知道在事件处理程序中写入什么代码。目前我只是在单击按钮时显示一个消息框，以确保事件正常。请帮忙。

!define IDC_BUTTON_SETPATH 1200 (1200 is the ID OF THE BUTTON ADDED from Resource hacker)

你没有说你正在使用哪个版本的MUI，这个宏应该同时处理......

!macro SetDirPageInstallDir text
!if "${MUI_SYSVERSION}" < "2.0"
Push $0
FindWindow $0 "#32770" "" $HWNDPARENT
GetDlgItem $0 $0 0x3FB
SendMessage $0 ${WM_SETTEXT} 0 "STR:${text}"
Pop $0
!else
SendMessage $mui.DirectoryPage.Directory ${WM_SETTEXT} 0 "STR:${text}"
!endif
!macroend


;In buttonclicked handler
!insertmacro SetDirPageInstallDir "$programfiles\Hello World"

使用ButtonEvent插件在MUI NSI安装程序中单击按钮时填充目录文本框
