# TODO List
#
# 1) Subitem selection;
# 2) Watermark? (almost, does not work very well :-( );
# 3) Groups? (Maybe, check ObjectListView);
# 4) Scrolling items as headers and footers;
# 5) Alpha channel for text/background of items;
# 6) Custom renderers for headers/footers (done);
# 7) Fading in and out on mouse motion (a la Windows Vista Aero);
# 8) Sub-text for headers/footers (grey text below the header/footer text);
# 9) Fixing the columns to the left or right side of the control layout;
# 10) Skins for header and scrollbars (implemented for headers/footers).

Description
===========
UltimateListCtrl is a class that mimics the behaviour of `wx.ListCtrl`, with almost
the same base functionalities plus some more enhancements. This class does
not rely on the native control, as it is a full owner-drawn list control.
In addition to the standard `wx.ListCtrl` behaviour this class supports:
Appearance
==========
* Multiple images for items/subitems;
* Images can be of any size and not limited to a single specific pair of `width`, `height`
as it is the case of `wx.ImageList`. Simply use L{PyImageList} instead of `wx.ImageList`
to add your images.
* Font, colour, background, custom renderers and formatting for items and subitems;
* Ability to add persistent data to an item using L{SetItemPyData} and L{GetItemPyData}:
the data can be any Python object and not necessarily an integer as in `wx.ListCtrl`;
* CheckBox-type items and subitems;
* RadioButton-type items and subitems;
* Overflowing items/subitems, a la `wx.grid.Grid`, i.e. an item/subitem may overwrite neighboring
items/subitems if its text would not normally fit in the space allotted to it;
* Hyperlink-type items and subitems: they look like an hyperlink, with the proper mouse
cursor on hovering;
* Multiline text items and subitems;
* Variable row heights depending on the item/subitem kind/text/window;
* User defined item/subitem renderers: these renderer classes **must** implement the methods
`DrawSubItem`, `GetLineHeight` and `GetSubItemWidth` (see the demo);
* Enabling/disabling items (together with their plain or grayed out icons);
* Whatever non-toplevel widget can be attached next to an item/subitem;
* Column headers are fully customizable in terms of icons, colour, font, alignment etc...;
* Column headers can have their own checkbox/radiobutton;
* Column footers are fully customizable in terms of icons, colour, font, alignment etc...;
* Column footers can have their own checkbox/radiobutton;
* Ability to hide/show columns;
* Default selection style, gradient (horizontal/vertical) selection style and Windows
Vista selection style.
And a lot more. Check the demo for an almost complete review of the functionalities.
Usage
=====
Usage example::
import sys
import wx
import wx.lib.agw.ultimatelistctrl as ULC
class MyFrame(wx.Frame):
def __init__(self):
wx.Frame.__init__(self, parent, -1, "UltimateListCtrl Demo")
list = ULC.UltimateListCtrl(self, wx.ID_ANY, agwStyle=wx.LC_REPORT|wx.LC_VRULES|wx.LC_HRULES|wx.LC_SINGLE_SEL)
list.InsertColumn(0, "Column 1")
list.InsertColumn(1, "Column 2")
index = list.InsertStringItem(sys.maxint, "Item 1")
list.SetStringItem(index, 1, "Sub-item 1")
index = list.InsertStringItem(sys.maxint, "Item 2")
list.SetStringItem(index, 1, "Sub-item 2")
choice = wx.Choice(list, -1, choices=["one", "two"])
index = list.InsertStringItem(sys.maxint, "A widget")
list.SetItemWindow(index, 1, choice, expand=True)
sizer = wx.BoxSizer(wx.VERTICAL)
sizer.Add(list, 1, wx.EXPAND)
self.SetSizer(sizer)
# our normal wxApp-derived class, as usual
app = wx.PySimpleApp()
frame = MyFrame(None)
app.SetTopWindow(frame)
frame.Show()
app.MainLoop()
Window Styles
=============
This class supports the following window styles:
=============================== =========== ====================================================================================================
Window Styles Hex Value Description
=============================== =========== ====================================================================================================
``ULC_VRULES`` 0x1 Draws light vertical rules between rows in report mode.
``ULC_HRULES`` 0x2 Draws light horizontal rules between rows in report mode.
``ULC_ICON`` 0x4 Large icon view, with optional labels.
``ULC_SMALL_ICON`` 0x8 Small icon view, with optional labels.
``ULC_LIST`` 0x10 Multicolumn list view, with optional small icons. Columns are computed automatically, i.e. you don't set columns as in ``ULC_REPORT``. In other words, the list wraps, unlike a `wx.ListBox`.
``ULC_REPORT`` 0x20 Single or multicolumn report view, with optional header.
``ULC_ALIGN_TOP`` 0x40 Icons align to the top. Win32 default, Win32 only.
``ULC_ALIGN_LEFT`` 0x80 Icons align to the left.
``ULC_AUTOARRANGE`` 0x100 Icons arrange themselves. Win32 only.
``ULC_VIRTUAL`` 0x200 The application provides items text on demand. May only be used with ``ULC_REPORT``.
``ULC_EDIT_LABELS`` 0x400 Labels are editable: the application will be notified when editing starts.
``ULC_NO_HEADER`` 0x800 No header in report mode.
``ULC_NO_SORT_HEADER`` 0x1000 No Docs.
``ULC_SINGLE_SEL`` 0x2000 Single selection (default is multiple).
``ULC_SORT_ASCENDING`` 0x4000 Sort in ascending order. (You must still supply a comparison callback in `wx.ListCtrl.SortItems`.)
``ULC_SORT_DESCENDING`` 0x8000 Sort in descending order. (You must still supply a comparison callback in `wx.ListCtrl.SortItems`.)
``ULC_TILE`` 0x10000 Each item appears as a full-sized icon with a label of one or more lines beside it (partially implemented).
``ULC_NO_HIGHLIGHT`` 0x20000 No highlight when an item is selected.
``ULC_STICKY_HIGHLIGHT`` 0x40000 Items are selected by simply hovering on them, with no need to click on them.
``ULC_STICKY_NOSELEVENT`` 0x80000 Don't send a selection event when using ``ULC_STICKY_HIGHLIGHT`` style.
``ULC_SEND_LEFTCLICK`` 0x100000 Send a left click event when an item is selected.
``ULC_HAS_VARIABLE_ROW_HEIGHT`` 0x200000 The list has variable row heights.
``ULC_AUTO_CHECK_CHILD`` 0x400000 When a column header has a checkbox associated, auto-check all the subitems in that column.
``ULC_AUTO_TOGGLE_CHILD`` 0x800000 When a column header has a checkbox associated, toggle all the subitems in that column.
``ULC_AUTO_CHECK_PARENT`` 0x1000000 Only meaningful foe checkbox-type items: when an item is checked/unchecked its column header item is checked/unchecked as well.
``ULC_SHOW_TOOLTIPS`` 0x2000000 Show tooltips for ellipsized items/subitems (text too long to be shown in the available space) containing the full item/subitem text.
``ULC_HOT_TRACKING`` 0x4000000 Enable hot tracking of items on mouse motion.
``ULC_BORDER_SELECT`` 0x8000000 Changes border colour whan an item is selected, instead of highlighting the item.
``ULC_TRACK_SELECT`` 0x10000000 Enables hot-track selection in a list control. Hot track selection means that an item is automatically selected when the cursor remains over the item for a certain period of time. The delay is retrieved on Windows using the `win32api` call `win32gui.SystemParametersInfo(win32con.SPI_GETMOUSEHOVERTIME)`, and is defaulted to 400ms on other platforms. This style applies to all views of `UltimateListCtrl`.
``ULC_HEADER_IN_ALL_VIEWS`` 0x20000000 Show column headers in all view modes.
``ULC_NO_FULL_ROW_SELECT`` 0x40000000 When an item is selected, the only the item in the first column is highlighted.
``ULC_FOOTER`` 0x80000000 Show a footer too (only when header is present).
``ULC_USER_ROW_HEIGHT`` 0x100000000 Allows to set a custom row height (one value for all the items, only in report mode).

``ULC_SMALL_ICON`` 0x8 Small icon view, with optional labels.
``ULC_LIST`` 0x10 Multicolumn list view, with optional small icons. Columns are computed automatically, i.e. you don't set columns as in ``ULC_REPORT``. In other words, the list wraps, unlike a `wx.ListBox`.
``ULC_REPORT`` 0x20 Single or multicolumn report view, with optional header.
``ULC_ALIGN_TOP`` 0x40 Icons align to the top. Win32 default, Win32 only.
``ULC_ALIGN_LEFT`` 0x80 Icons align to the left.
``ULC_AUTOARRANGE`` 0x100 Icons arrange themselves. Win32 only.
``ULC_VIRTUAL`` 0x200 The application provides items text on demand. May only be used with ``ULC_REPORT``.
``ULC_EDIT_LABELS`` 0x400 Labels are editable: the application will be notified when editing starts.
``ULC_NO_HEADER`` 0x800 No header in report mode.
``ULC_NO_SORT_HEADER`` 0x1000 No Docs.
``ULC_SINGLE_SEL`` 0x2000 Single selection (default is multiple).

``ULC_TILE`` 0x10000 Each item appears as a full-sized icon with a label of one or more lines beside it (partially implemented).
``ULC_NO_HIGHLIGHT`` 0x20000 No highlight when an item is selected.

``ULC_AUTO_CHECK_PARENT`` 0x1000000 Only meaningful foe checkbox-type items: when an item is checked/unchecked its column header item is checked/unchecked as well.
``ULC_SHOW_TOOLTIPS`` 0x2000000 Show tooltips for ellipsized items/subitems (text too long to be shown in the available space) containing the full item/subitem text.
``ULC_HOT_TRACKING`` 0x4000000 Enable hot tracking of items on mouse motion.
``ULC_BORDER_SELECT`` 0x8000000 Changes border colour whan an item is selected, instead of highlighting the item.
``ULC_TRACK_SELECT`` 0x10000000 Enables hot-track selection in a list control. Hot track selection means that an item is automatically selected when the cursor remains over the item for a certain period of time. The delay is retrieved on Windows using the `win32api` call `win32gui.SystemParametersInfo(win32con.SPI_GETMOUSEHOVERTIME)`, and is defaulted to 400ms on other platforms.
