创建多选和排序listbox列表控件及操作

${NSD_CreateListBox} 用于创建列表框

但是创建出来的列表框是无法多选和列表本身会自动排序

所以我们可以自己定义一个

创建多选和排序列表

;Usage:
 ${NSD_NSD_CreateSortedListBox} X Y 宽 高 ""
!Define NSD_CreateSortedListBox "nsDialogs::CreateControl ${__NSD_ListBox_CLASS} ${__NSD_ListBox_STYLE}|${LBS_SORT}|${LB}

由于可以多选,删除所选的列表项时我们再写一个删除宏${NSD_LB_DelSelectString}
/*
删除所选的列表项目
Usage:
${NSD_LB_DelSelectString} CONTROL
*/

Var D8_itemCount
Var D8_address
Var D8_selItemCount
!macro __NSD_LB_DelSelectString CONTROL
 #获得项目数$ItemCount
 SendMessage ${CONTROL} ${LB_GETCOUNT} $0 $0 $D8_itemCount
 #分配项目数$ItemCount内存
 IntOp $0 $D8_itemCount * 4
 System::Alloc $0
 Pop $D8_address
 #给选定的项目分配内存
 SendMessage ${CONTROL} ${LB_GETSELITEMS} $D8_itemCount $D8_address $D8_selItemCount
 ${If} $D8_selItemCount > 0
 ;计算最后一项目的地址
 IntOp $5 $D8_selItemCount - 1
 IntOp $5 $5 * 4
 IntOp $D8_address $D8_address + $5
 ;删除选定index项目,所以从最后项目删除到第一个项目。
 ${For} $R1 1 $D8_selItemCount
 #获取选定项目index
 System::Call "*$D8_address(i .r0)"
 System::Call user32::SendMessage(i${CONTROL},i${LB_GETTEXT},i$0,t.r1)
 SendMessage ${CONTROL} ${LB_DELETESTRING} $0 `STR:$1`
 #移动到下一个index
 IntOp $D8_address $D8_address - 4
 ${Next}
 ${Endif}
 System::Free $D8_address
!macroend

最后我们的实现的脚本

!include "nsDialogs.nsh"
!include "winmessages.nsh"
!include "logiclib.nsh"
!include "nsDialogs_LB_DelSelectString.nsh"
