Smartphone List View usage logs

Create a List View Control

// Create listview

Hwndret = createwindow (wc_listview, null,

Ws_child |

Ws_visible |

Lvs_report |

/* Lvs_ownerdata | * // description 1

Lvs_nocolumnheader,

0,

0,

Mainrect. Right-mainrect. Left,

Mainrect. Bottom-mainrect. Top,

Hwndprnt,

(Hmenu) id_listview, // Control ID

G_hinst, 0 );

 

Note 1: If lvs_ownerdata Peugeot is added when a listview is created, the system will not plot the content inserted by listview_insertitem. The programmer must process the content at wm_notify. The following is an example:

 

Case wm_notify:

If (id_listview = wparam)

Return onlistviewnotify (hwnd, lparam );

Break;

 

Lresult onlistviewpolicy (hwnd, lparam)

{

Nmhdr * pnmh = (nmhdr *) lparam;

Lresult = 0;

 

Switch (pnmh-> code)

{

Case lvn_getdispinfo:

{

Lv_dispinfo * PDI = (lv_dispinfo *) lparam;

 

If (0 = PDI-> item. isubitem)

{

If (PDI-> item. Mask & lvif_text)

{

Wcscpy (PDI-> item. psztext, l "1213213421 ");

PDI-> item. cchtextmax = wcslen (PDI-> item. psztext );

PDI-> item. iItem;

}

 

If (PDI-> item. Mask & lvif_image)

{

PDI-> item. iimage = 0;

}

}

Else

{

If (PDI-> item. Mask & lvif_text)

{

PDI-> item. psztext;

PDI-> item. cchtextmax;

PDI-> item. iItem;

PDI-> item. isubitem;

}

}

}

Break;

 

Case lvn_itemactivate:

Break;

 

// Handle this variable Y if you want to use the number keys to select

// Items in the view (like how the desktop file explorer lets you

// Select files by typing the first few characters of the file name .)

// This operation y is also used then the control is sent an lvm_finditem

Case lvn_odfinditem:

{

Nmlvfinditem * pfinditem = (nmlvfinditem *) lparam;

// Used if you are trying to find an item in the List View

}

Break;

}

 

Return (lresult );

}

 

Otherwise, the system will not send the wm_notify event, and automatically draw the content added by listview_insertitem.
