Header file for creating Listview control
In an NSIS forum "dreams8.com", a member named "gfm688" writes a header file to create and handle a listview control with the report view. This header file is modified by me. I add some new macros, include some for ComboBox and ListBox.
See this attachment for details, 8 examples included.
ListView.zip (328 KB)
All macros in this header:
${NSD_RemoveStyle} hWnd Styles
Removes one or more window style from a control. From MSDN: For some styles in certain controls (the ES_READONLY style in the edit control, for example), it may not properly change the style because the control may need to perform special internal processing. In these cases, a corresponding message to change the style will be available (EM_SETREADONLY in the example mentioned).
${NSD_RemoveExStyle} hWnd ExStyles
Removes one or more extended window style from a control. May not take effect in some cases for the above saying.
${NSD_CB_DelString} hComboBox string
Deletes the specified string from a combobox. Note: If the string you specified is not exist in a combo box, the first string that contains what you specified will be deleted. For example: there are 4 items in a combo box: First, Second, Seconds, Secondary. If you want to delete the string "sec", the first one which contains "sec" from top - "Second" will be deleted.
${NSD_CB_Clear} hComboBox
Deletes all strings from a ComboBox control (no return value).
${NSD_CB_GetCount} hComboBox outVar
Retrieves the number of strings from a ComboBox control.
${NSD_CB_GetSelection} hComboBox outVar
Retrieves the selected string from a ComboBox control.
${NSD_LB_DelString} hListBox String #redefined in header
Deletes the specified string from a ListBox control. The macro command NSD_LB_DelString in nsDialogs.nsh always deletes the first string but not the specified one. I write a new macro to replace it, and undefine the original one in this file. Note: If the string you specified is not exist in a list box, the first string that contains what you specified will be deleted.
${NSD_LB_Clear} hListBox #redefined in header
Deletes all strings from a ListBox control (no return value). The macro command NSD_LB_Clear in nsDialogs.nsh needs two parameters, but the readme file of nsDialogs said the macro needs only one parameter, it is exactly the handle of the listbox. This macro is redefined as the above one, it doesn't return a value.
${NSD_LV_InsertColumn} hListview iCol cx szText
Inserts a new column to a listview control (report view). To delete a column from a listview control, just sending the LVM_DELETECOLUMN message - SendMessage hListview ${LVM_DELETECOLUMN} iCol 0.
${NSD_LV_DeleteColumn} hListview iCol
Deletes a column from a listview control (report view). Same as LVM_DELETECOLUMN message.
${NSD_LV_InsertItem} hListview iItem szText
Inserts a new item to a listview control (report view). To delete an item from a listview control, just sending the LVM_DELETECOLUMN message - SendMessage listview_HWND ${LVM_DELETEITEM} iItem 0.
${NSD_LV_DeleteItem} hListview iItem
Deletes an item from a listview control (report view). Same as LVM_DELETEITEM message.
${NSD_LV_GetItemText} hListview iItem iSubItem outVar
Retrieves the text of an item or its subitem from an item of listview control (report view). To retrieve the item's text, pass iSubItem with 0 (zero).
${NSD_LV_SetItemText} hListview iItem iSubItem szText
Sets the text of an item or its subitem (inserts a new subitem) to an item of listview control (report view). To set the item's text, pass iSubItem with 0 (zero).
${NSD_LV_SetItemImage} hListview iItem iImage
Sets the icon of an item of listview (report view). Before using this you must create an ImageList first that contains one or more bitmaps or icons. See examples in the above attachment for details.
${NSD_LV_GetCheckState} hListview iItem outVar
Retrieves the state of an item in a listview control with checkboxes extended style. Result may be 1, represents the item is checked, or 0 represents unchecked. Before using this you must send the LVM_SETEXTENDEDLISTVIEWSTYLE message to set the LVS_EX_CHECKBOXES extended style.
${NSD_LV_SetCheckState} hListview iItem State
Checks or umchecks an item in a listview control with checkboxes extended style. Pass "State" with 1 (one) to check it or 0 (zero) to uncheck it. Before using this you must send the LVM_SETEXTENDEDLISTVIEWSTYLE message to set the LVS_EX_CHECKBOXES extended style.
To set the text color, background color, set column width, etc. You can also using SendMessage simplely.
For example:
SendMessage $HWND ${LVM_DELETEITEM} 2 0, deletes the 2nd (zero-based) item.
SendMessage $HWND ${LVM_DELETECOLUMN} 4 0, deletes the 4th (zero-based) column.
SendMessage $HWND ${LVM_SETBKCOLOR} 0 0xFF0000, sets the background color to red.
Parameters of each message can be found on msdn. All messages of listview control: http://msdn.microsoft.com/en-us/library/ff485961.aspx.
Example 1
/* Listview styles are defined in header file */ !include "MUI2.nsh" !include "CommCtrl.nsh" Name "List View Example" OutFile ListView.exe Page custom CreatePage !insertmacro MUI_LANGUAGE "English" Function CreatePage !insertmacro MUI_HEADER_TEXT "List view" "A listview control created by nsDialogs" nsDialogs::Create 1018 Pop $0 StrCmp $0 error 0 +2 Abort ${NSD_CreateListView} 0u 0u 300u 140u "Listview" Pop $1 ; ${NSD_LV_InsertColumn} hwnd col_idx_0_based col_width col_text ${NSD_LV_InsertColumn} $1 0 200 "column 0" ${NSD_LV_InsertColumn} $1 1 100 "column 1" ${NSD_LV_InsertColumn} $1 2 100 "column 2" ; ${NSD_LV_InsertItem} hwnd item_idx_0_based item_text ${NSD_LV_InsertItem} $1 0 'Item 0' ; ${NSD_LV_SetItemText} hwnd item_idx_0_based subitem_idx_1_based subitem_text ${NSD_LV_SetItemText} $1 0 1 'Subitem 0_1' ${NSD_LV_SetItemText} $1 0 2 'Subitem 0_2' ${NSD_LV_InsertItem} $1 1 'Item 1' ${NSD_LV_SetItemText} $1 1 2 'Subitem 1_2' ${NSD_LV_InsertItem} $1 2 'Item 2' ${NSD_LV_SetItemText} $1 2 1 'Subitem 2_1' nsDialogs::Show FunctionEnd Section -Main SectionEnd
Compile the script and run, you will see a page like this:
