|
|
* NOTES
|
|
* Listview control implementation.
|
|
*
|
|
* TODO:
|
|
* 1. No horizontal scrolling when header is larger than the client area.
|
|
* 2. Drawing optimizations.
|
|
* 3. Hot item handling.
|
|
*
|
|
* Notifications:
|
|
* LISTVIEW_Notify : most notifications from children (editbox and header)
|
|
*
|
|
* Data structure:
|
|
* LISTVIEW_SetItemCount : not completed for non OWNERDATA
|
|
*
|
|
* Advanced functionality:
|
|
* LISTVIEW_GetNumberOfWorkAreas : not implemented
|
|
* LISTVIEW_GetISearchString : not implemented
|
|
* LISTVIEW_GetBkImage : not implemented
|
|
* LISTVIEW_SetBkImage : not implemented
|
|
* LISTVIEW_GetColumnOrderArray : simple hack only
|
|
* LISTVIEW_SetColumnOrderArray : simple hack only
|
|
* LISTVIEW_Arrange : empty stub
|
|
* LISTVIEW_ApproximateViewRect : incomplete
|
|
* LISTVIEW_Update : not completed
|
|
*
|
|
* Known differences in message stream from native control (not known if
|
|
* these differences cause problems):
|
|
* LVM_INSERTITEM issues LVM_SETITEMSTATE and LVM_SETITEM in certain cases.
|
|
* LVM_SETITEM does not always issue LVN_ITEMCHANGING/LVN_ITEMCHANGED.
|
|
* WM_PAINT does LVN_GETDISPINFO in item order 0->n, native does n->0.
|
|
* WM_SETREDRAW(True) native does LVN_GETDISPINFO for all items and
|
|
* does *not* invoke DefWindowProc
|
|
* WM_CREATE does not issue WM_QUERYUISTATE and associated registry
|
|
* processing for "USEDOUBLECLICKTIME".

* LISTVIEW_ProcessLetterKeys
|
|
*
|
|
* Processes keyboard messages generated by pressing the letter keys
|
|
* on the keyboard.
|
|
* What this does is perform a case insensitive search from the
|
|
* current position with the following quirks:
|
|
* - If two chars or more are pressed in quick succession we search
|
|
* for the corresponding string (e.g. 'abc').
|
|
* - If there is a delay we wipe away the current search string and
|
|
* restart with just that char.
|
|
* - If the user keeps pressing the same character, whether slowly or
|
|
* fast, so that the search string is entirely composed of this
|
|
* character ('aaaaa' for instance), then we search for first item
|
|
* that starting with that character.
|
|
* - If the user types the above character in quick succession, then
|
|
* we must also search for the corresponding string ('aaaaa'), and
|
|
* go to that string if there is a match.
|
|
*
|
|
* PARAMETERS
|
|
* [I] hwnd : handle to the window
|
|
* [I] charCode : the character code, the actual character
|
|
* [I] keyData : key data
|
|
*
|
|
* RETURNS
|
|
*
|
|
* Zero.
|
|
*
|
|
* BUGS
|
|
*
|
|
* - The current implementation has a list of characters it will
|
|
* accept and it ignores averything else. In particular it will
|
|
* ignore accentuated characters which seems to match what
|
|
* Windows does. But I'm not sure it makes sense to follow
|
|
* Windows there.
|
|
* - We don't sound a beep when the search fails.
