digitalmars.D.dwt - dwt-win Path bug with tango 0.99.7

reply yidabu <yidabu.spam gmail.com> writes:
theres is Break change in tango 0.99.7L
Backslashes ( \ ) are no longer accepted as in FilePath and PathParser - use
Path.standard before passing paths to them. 

for example,
dwtx.jface.preference.DirectoryFieldEditor

line 59:
auto f = new FilePath(getTextControl().getText());
sholud be:
auto f = new FilePath(Path.standard(getTextControl().getText()));

otherwise, fileDialog.setFilterPath(startingDirectory.path); will failure.

all modules imported FilePath or Path should do a check, my program crashed:
Exception occurred
Exception of type tango.core.Exception.IOException in (0): unexpected '\'
character in path: C:\Documents and Settings\Administrator\Application
Data\Software

I haven't found the issue this time.

modules that import FilePath:

D:/d/dmd/src/dwt-addons/dwtx/jface/preference/DirectoryFieldEditor.d
D:/d/dmd/src/dwt-addons/dwtx/jface/preference/FileFieldEditor.d
D:/d/dmd/src/dwt-addons/dwtx/jface/preference/PathEditor.d
