@class wxListCtrl
|

@wxheader{listctrl.h}
|
|
|
|
A list control presents lists in a number of formats: list view, report view,
|
|
icon view and small icon view. In any case, elements are numbered from zero.
|
|
For all these modes, the items are stored in the control and must be added to
|
|
it using wxListCtrl::InsertItem method.
|
|
|
|
A special case of report view quite different from the other modes of the list
|
|
control is a virtual control in which the items data (including text, images
|
|
and attributes) is managed by the main program and is requested by the control
|
|
itself only when needed which allows to have controls with millions of items
|
|
without consuming much memory. To use virtual list control you must use
|
|
wxListCtrl::SetItemCount first and overload at least
|
|
wxListCtrl::OnGetItemText (and optionally
|
|
wxListCtrl::OnGetItemImage or wxListCtrl::OnGetItemColumnImage and
|
|
wxListCtrl::OnGetItemAttr) to return the information
|
|
about the items when the control requests it. Virtual list control can be used
|
|
as a normal one except that no operations which can take time proportional to
|
|
the number of items in the control happen -- this is required to allow having a
|
|
practically infinite number of items. For example, in a multiple selection
|
|
virtual list control, the selections won't be sent when many items are selected
|
|
at once because this could mean iterating over all the items.
|
|
|
|
Using many of wxListCtrl features is shown in the
|
|
@ref overview_samplelistctrl "corresponding sample".
|
|
|
|
To intercept events from a list control, use the event table macros described
|
|
in wxListEvent.
|
|
|
|
@b Mac Note: Starting with 2.8, wxListCtrl uses a native implementation for
|
|
report mode, and uses a generic implementation for other modes. You can use the
|
|
generic implementation for report mode as well by setting the
|
|
mac.listctrl.always_use_generic wxSystemOption to
|
|
1.
|
|
|
|
@beginStyleTable
|
|
@style{wxLC_LIST}:
|
|
Multicolumn list view, with optional small icons. Columns are
|
|
computed automatically, i.e. you don't set columns as in
|
|
wxLC_REPORT. In other words, the list wraps, unlike a wxListBox.
|
|
@style{wxLC_REPORT}:
|
|
Single or multicolumn report view, with optional header.
|
|
@style{wxLC_VIRTUAL}:
|
|
The application provides items text on demand. May only be used
|
|
with wxLC_REPORT.
|
|
@style{wxLC_ICON}:
|
|
Large icon view, with optional labels.
|
|
@style{wxLC_SMALL_ICON}:
|
|
Small icon view, with optional labels.
|
|
@style{wxLC_ALIGN_TOP}:
|
|
Icons align to the top. Win32 default, Win32 only.
|
|
@style{wxLC_ALIGN_LEFT}:
|
|
Icons align to the left.
|
|
@style{wxLC_AUTOARRANGE}:
|
|
Icons arrange themselves. Win32 only.
|
|
@style{wxLC_EDIT_LABELS}:
|
|
Labels are editable: the application will be notified when editing
|
|
starts.
|
|
@style{wxLC_NO_HEADER}:
|
|
No header in report mode.
|
|
@style{wxLC_SINGLE_SEL}:
|
|
Single selection (default is multiple).
|
|
@style{wxLC_SORT_ASCENDING}:
|
|
Sort in ascending order (must still supply a comparison callback in
|
|
SortItems.
|
|
@style{wxLC_SORT_DESCENDING}:
|
|
Sort in descending order (must still supply a comparison callback
|
|
in SortItems.
|
|
@style{wxLC_HRULES}:
|
|
Draws light horizontal rules between rows in report mode.
|
|
@style{wxLC_VRULES}:
|
|
Draws light vertical rules between columns in report mode.
