Header file for Listview

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 macro commands.

See the attachment for details, 8 examples included.

ListView.zip (328 KB)

There are some macro commands in this file:

• ${NSD_RemoveStyle} control_HWND style

Removes one or more window style from a control.

• ${NSD_RemoveExStyle} control_HWND style

Removes one or more extended window style from a control.

• ${NSD_CB_DelString} combo_HWND string

Deletes the specified string from a combobox.

• ${NSD_CB_Clear} combo_HWND

Deletes all strings from a combobox (no return value).

• ${NSD_CB_GetCount} combo_HWND output_var

Retrieves the number of strings from a combobox.

• ${NSD_CB_GetSelection} combo_HWND output_var

Retrieves the selected string from a combobox.

• ${NSD_LB_DelString} listbox_HWND string # the redefined one

Deletes the specified string from a list box. 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.

• ${NSD_LB_Clear} listbox_HWND # the redefined one

Deletes all strings from a list box (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} listview_HWND col_idx col_w text

Inserts a new column to a listview (report view).

• ${NSD_LV_InsertItem} listview_HWND item_idx text

Inserts a new item to a listview (report view).

• ${NSD_LV_SetSubItem} listview_HWND item_idx subitem_idx text

Inserts a new subitem to an item of listview (report view).

• ${NSD_LV_SetItemIcon} listview_HWND item_idx icon_idx

Sets the icon of an item of listview (report view).

• ${NSD_LV_SetItemChecked} listview_HWND item_idx

Checks an item of a listview with checkboxes extended style.

• ${NSD_LV_GetItemText} listview_HWND item_idx subitem_idx output_var

Retrieves the text of an item of a listview.
