Description
Version: 0.2 - 20181123
Supported on: Win95+/NT4+ (Only tested on XP, should work on any platform)
This plugin will respond to files dropped on the window you specify, it can call a nsis function for each file/folder dropped on the window, or just set the window's text (Useful for file/folder inputs)
Example
OutFile Test.exe ShowInstDetails show RequestExecutionLevel user CompletedText "Drop files on me..." DirText "You can drop a folder on the text field!" SpaceTexts none InstallDir $temp Page Directory "" onDirShow Page InstFiles Function onDirShow FindWindow $1 "#32770" "" $HWNDPARENT ; Find inner dialog GetDlgItem $1 $1 0x3FB ; Get the handle of the control (Replace with INSTALLOPTIONS_READ ... "HWND" on a custom page) HandleFileDragDrop::Register $1 "" FunctionEnd Function InstPageDrop DetailPrint Drop:$0 StrCpy $0 "" ; Set to empty string if you want the next file (if any) FunctionEnd Section FindWindow $1 "#32770" "" $HWNDPARENT ; Find inner dialog GetFunctionAddress $0 InstPageDrop HandleFileDragDrop::Register $1 $0 SectionEnd
Remarks
In Windows Vista and later UIPI (an UI component of UAC) blocks drag & drop from low integrity processes (like Explorer) to high integrity processes (like the installer if set to require elevation). To work this around, add the following code:
System::Call 'user32::ChangeWindowMessageFilter(i563, i1)' System::Call 'user32::ChangeWindowMessageFilter(i74, i1)' System::Call 'user32::ChangeWindowMessageFilter(i73, i1)'
