wxMkDir return false even if it successfully creates the directory.

Post by apoorv569 »

I'm trying to check if a directory exists, and if not I want to make that directory, so I wrote this,

Code: Select all

#define CONFIG_DIR wxStandardPaths::Get().GetUserConfigDir() + "/.config/SampleHive"

    if (!wxDirExists(CONFIG_DIR))
    {
        if (!wxMkDir(CONFIG_DIR, wxPOSIX_USER_READ | wxPOSIX_USER_WRITE | wxPOSIX_USER_EXECUTE |
                     wxPOSIX_GROUP_READ | wxPOSIX_GROUP_EXECUTE |
                     wxPOSIX_OTHERS_READ | wxPOSIX_OTHERS_EXECUTE))
        {
            wxMessageBox(wxString::Format(_("Error! Could not create directory %s"), CONFIG_DIR), _("Error!"),
                         wxOK | wxCENTRE, this);
        }
    }
The does work, and it creates the directory,

but it still shows the error, the first time I open the app, after that it doesn't. Is this is a bug, or is there something that I missed?

Use wxFileName::Mkdir with flag wxPATH_MKDIR_FULL. Then you don't need the wxDirExists.

Use the source, Luke!

Is there a function to delete a file in wxFileName? I could not find one, there is RmDir(), can it also delete files? Currently I'm doing like this,

Code: Select all

void MainFrame::OnSelectResetAppData(wxCommandEvent& event)
{
    wxMessageDialog clearDataDialog(this, wxString::Format(_("Warning! This will delete configuration file %s and database %s permanently, "
                                                             "are you sure you want to delete these files?"), m_ConfigFilepath, m_DatabaseFilepath),
                                    "Clear app data", wxYES_NO | wxNO_DEFAULT | wxCENTRE, wxDefaultPosition);

    switch (clearDataDialog.ShowModal())
    {
        case wxID_OK:
            if (wxRemoveFile(m_ConfigFilepath) && wxRemoveFile(m_DatabaseFilepath))
            {
                wxMessageBox(_("Successfully cleared app data"), _("Success"), wxOK | wxCENTRE, this);
            }
            else
            {
                wxLogDebug("Could not clear app data");
            }
            break;
        case wxID_NO:
            break;
        default:
            break;
    }
}
This works it deletes both files, but the wxMessageBox does not show up, neither the wxLogDebug in the else statement.

That's because i deleted it.

wxRemoveFile should work fine and the code looks ok. One of the two paths must be taken, try a debugger to find out which one.

You create clearDataDialog with wxYES_NO style but delete the files when its ShowModal() returns wxID_OK. I wonder how that can work.

I assume you are aware that the user probably will not see the message of wxLogDebug(), unless it works differently on Linux than on Windows (Debug vs Release builds).

Ah! Yes, this was the problem, I was checking for wxID_OK instead of wxID_YES.

Yes, I am aware of this, the wxLogDebug() statements are for me only. If I want to show something to user, I use wxInfoBar or wxMessageBox.
