The same value of 80px was used in both the generic and MSW versions of wxListCtrl, so introduce a symbolic name for it and define it only once, similarly to how it's already done for wxDVC_DEFAULT_WIDTH and WXGRID_DEFAULT_COL_WIDTH. No real changes.

// Problem:
|

// The MSW version had problems with SetTextColour() et

// item index. If a item was inserted anywhere but the end
|
|
// of the list the text attributes (colour etc) for
|
|
// the following items were out of sync.
|
|
//
|
|
// Solution:
|
|
// Under MSW the only way to associate data with a List
|
|
// item independent of its position in the list is to
|
|
// store a pointer to it in its lParam attribute. However
|
|
// user programs are already using this (via the

// SetItemData() GetItemData() calls).

// a lParam -- and this is what wxMSWListItemData does.

6.0, i.e. when not using a manifest in which case 5.82 is used.
|
|
And even then it only happens when "Show window contents while
|
|
dragging" is enabled under Windows, resulting in live updates
|
|
when resizing columns. Note that even with that setting on, at
|
|
least under Windows 7 and 10 no live updating is done when
|
|
using ComCtl32 5.82.
|
|
|
|
Revision b66c3a67519caa9debfd76e6d74954eaebfa56d9 made this fix
|
|
almost redundant, except that when you do NOT handle
|
|
EVT_LIST_COL_DRAGGING (or do and skip the event) the trailing
|
|
pixels still appear. In case of wanting to reproduce the
|
|
problem in the listctrl sample: comment out handling oF
|
|
EVT_LIST_COL_DRAGGING and also set useDrawFix to false and gap
|
|
to 2 (not 0).
