    Hi community.

    I want to choose a Directory with the build in DirectoryChooser.
    So far so good.
    Problem or wish is:
    In this "Dialog" i want to see also the files, so i can decide which Directory i will select!!
    Like with the Filechooser, but there i cant choose a Directory.

    Is this not possible, or do i miss something?

    It is not possible. You can use the FileChooser and get the folder from the selected file, with File.GetFileParent.
     
    ShaneG30 and Patent like this.

    thanks erel for your hint.
    thats not exactly what i want, so i tried it with the swing filechooser.
    works roughly perfect, but one thing:
    as it should, it is a "modal" dialog.
    but because of no fx, it "blocks" the main thread. this has no negative effect, but the mainform becomes white with -no response- while the dialog is open.
    its more an optical drawback. no cpu load.
    is there a possibility to avoid this?

    Code:
    Dim jframe As JavaObject
        jframe.Initializenewinstance(
    "javax.swing.JFrame",Null)       
        jframe.RunMethod(
    "setSize",Array(600,600))
        jframe.RunMethod(
    "setAlwaysOnTop",Array(True))
           
        
    Dim jfilechooser As JavaObject
        jfilechooser.Initializenewinstance(
    "javax.swing.JFileChooser",Null)
        jfilechooser.RunMethod(
    "setFileSelectionMode",Array(2))        'be able to select files or directories
        jfilechooser.RunMethod("showDialog",Array(jframe,"Select")) 
        
    Log(jfilechooser.RunMethod("getSelectedFile",Null))            'null or fullpath

    Why can't you use the JFX FileChooser?

    all in all i want to choose a directory.
    when this dir is empty i cant choose it with filechooser and its not the best thing to tell the user "choose a file to select the directory".
    directorychooser should be ok, but i want to see the files in the directories.
    the option to do this was just available in the old swing-chooser :(

    I see. I don't have any suggestion about the message queue processing. Never tried it.

    Hi Patent,

    Maybe you can still use the following code which works for me. It is based on the FileChosen and a comment from Erel; which I found on one of the questions on the forum. The global variable DirPath function is to bring the user back to his previous directory choice.
    Code:
    Dim FileChosen As String
    FileChosen = fc.ShowOpen(Mainform)
       
    '   We can use the FileChooser and get the folder from the selected file, with File.GetFileParent.
    Filename1 = FileChosen.Trim
       
    '   Divide directory and filename
    DirPath = File.GetFileParent(Filename1)
    Filename1 = Filename1.Replace(DirPath, 
    "")
