Update of /cvsroot/wnd/wnd/wnd/custom In directory sc8-pr-cvs1.sourceforge.net:/tmp/cvs-serv31354 Modified Files: splitter.py Added Files: drivecombo.py Log Message: bit of this and a bit of that --- NEW FILE: drivecombo.py --- """ TODO - winos.GetDriveList fails sometimes - limit dropdown height if style 'adjusth' is used.

NOTES - comboboxes do not send any reliable notification when being enabled or disabled, so no special drawing is done here - SetFont/GetFont not implemented; If the user sets a non-default font this control will mess up. - item offets are calculated as follows: icon -> text = font.GetAverageCharWidth item -> nextItem = font.GetAverageCharWidth/2 """ from wnd import gdi from wnd.api import shell from wnd.api import winos from wnd.controls.imagelist import Imagelist from wnd.controls.helpers import ParseStylesSZ from wnd.custom.odcombobox import ODCombobox from wnd.wintypes import user32 #::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::: SZ_MSG_SHELLNOTIFY= "wnd_DriveCombo_notify" STYLES= ('adjusth', 'largeicon', 'monitorchanges', 'showdetails', 'smallicon', ) #********************************************************************************** #********************************************************************************** class Data(object): __slots__= ('Combobox', 'Imagelist', 'Shell', 'ShellNotify', 'msgNotify', 'styles', 'isNotifyRegistered') def __init__(self): self.Combobox= None self.Imagelist= None self.Shell= None self.ShellNotify= None self.msgNotify= None self.isNotifyRegistered= False self.styles= [] def Close(self): try: self.Shell.Close() except: pass try: self.ShellNotify.Close() except: pass try: self.Imagelist.Close() except: pass def SHN_StartMonitor(self): if not self.isNotifyRegistered: self.Shell.OpenSpecialFolder(shell.CLSIDL_DRIVES) pIdl= self.Shell.GetCwd() self.ShellNotify.Register(pIdl, 'mediainserted', 'mediaremoved', 'driveremoved', 'driveadd') shell.PidlFree(pIdl) self.Shell.SetCwd(None) self.isNotifyRegistered= True def SHN_StopMonitor(self): if self.isNotifyRegistered: self.ShellNotify.Close() self.isNotifyRegistered= False def _printPidls(self, msg, wp, lp): ## helper for 'shellnotify' message if lp==None: return out= [] if isinstance(lp, tuple): if lp[0]: out.append(self.Shell.GetParseName(lp[0])) else: out.append(None) if lp[1]: out.append(self.Shell.GetParseName(lp[1])) else: out.append(None) else: if lp: out.append(self.Shell.GetParseName(lp)) else: out.append(None) print msg, wp, out #********************************************************************************** #********************************************************************************** class DriveCombo(object): def __init__(self, parent, x, y, w, h, *styles): self._custom_Data= Data() for i in styles: if i not in STYLES: raise ValueError, "invalid style: %s" % i self._custom_Data.styles= styles self.Hwnd= 0 self._custom_Data.Combobox=ODCombobox(parent) self._custom_Data.Combobox.onMSG= self.onMESSAGECombobox self._custom_Data.Combobox.InitCombobox(x, y, w, h, 'ownerdrawvariable', 'hasstrings', 'dropdownlist') self.Hwnd= self._custom_Data.Combobox.GetContainer().Hwnd self._custom_Data.Shell= shell.ShellNamespace() self._custom_Data.msgNotify= user32.RegisterWindowMessageA(SZ_MSG_SHELLNOTIFY) self._custom_Data.ShellNotify= shell.ShellNotify( self._custom_Data.Combobox, self._custom_Data.msgNotify, self.onMESSAGECombobox) self._custom_Data.Combobox.HandleMessage(self._custom_Data.msgNotify) if 'monitorchanges' in self._custom_Data.styles: self._custom_Data.SHN_StartMonitor() self.Refresh() #-------------------------------------------------------------------------------------------- #
