[Muhammad Goni]

Hello Group member, i am Looking for a Class like QFolderDialog or how i can select folder using QT classes? And how to get selected path

[CalmoSoft]

Hello Muhammad,

To select a folder use QFileDialog class.

To get the selected path use the CurrentDir() function.

Code:

see CurrentDir() + nl

Output:

C:\Ring\calmosoft

But the qfiledialog is for files what if the selected item is file?

[Mahmoud Fayed]

Hello Muhammad

In the stdlib.ring, You have

(1) JustFilePath()  : http://ring-lang.sourceforge.net/doc1.6/stdlib.html#justfilepath-function
(2) JustFileName() : http://ring-lang.sourceforge.net/doc1.6/stdlib.html#justfilename-function

Using these two functions, You can process the string to get the path or the file name only

Greetings,
Mahmoud

You didnt understand me, i said i only want to select folder instead of file, for e.g in C# winform we've class for Folder FolderBrowserDialog and for file is FileBrowserDialog
so, in ring qt what is equivalent to folderbrowserdialog?

[Mahmoud Fayed]

Hello Muhammad

We have the next method in the QFileDialog class

QString getExistingDirectory(QWidget *,QString,QString, QFileDialog::Option)

Example:

load "guilib.ring"

new qApp {
    w = new qWidget() {
        oFile = new qFileDialog(w)
        cFolder = oFile.getExistingDirectory(w,"Open Directory","c:\",0)
        w.setWindowTitle(cFolder)
        show()
    }
    exec()
}
