XOJO FILE FOLDER PICKER CODE
Try to run the previous fragment of code on several operating systems virtual machines are a great help for thisand you will see how Xojo points to the right path in every case. For example, if we want to get the right reference to the Documents folder on every supported deployment OS, we would have to use this fragment of code. This is the way to go, for example, when we want to point to the Documents folder or other specific folders such as Library or Cache. For these cases Xojo offers the GetOpenFolderItem function, passing along as a unique parameter the string representing, as a filter, the kind of files our app is interested in. I mean, this is what happens, for example, when using most of the apps that allows us to choose the file via a File Dialog Box a Window that brings access to the OS file system showing all the files that are compatibles with the app. This way we avoid the use of multiple if…then…else in the same code fragment. Or, preferably, catching the exceptions as in the following example. For these cases, you can turn to the use of the conditional compilation clause If… Then… Endifproviding the native path variation expected by the OS under which your app is running. It is important to point out the fact that the path format, as Stringis the native one to the platform over which we are going to deploy the app, something you have to consider if you want to create a multiplatform app. With the previous line of code we will be using the FolderItem class Constructorpassing along as the argument the native path to the file we want to get the reference to, if it already exists or to the file our app expects to create. Semicolon separated list of file types the user can open.In both scenarios, the most basic way to go is the same. The result will be Nil if the user clicked the Cancel button. Represents the file that was opened by the user. Instead of creating your file types in code, you can use the Common File Types feature to set these properties.
It displays a pop-up menu of the most common types and a "More" button that displays a much larger pop-up.

This code opens an mp4 file and then opens it as a movie. You can test for this by comparing the FolderItem with the Nil value. If the user clicks the Cancel button in the open file dialog box, the FolderItem will be Nil. Aliases are resolved, so if the user chooses an alias file, the returned FolderItem will be to the file pointed to by the alias. See the FolderItem class for more information.

If you want to display all files, you will need to add a file type to the project that uses "? You can then use the FolderItem to access various data about the file such as its name, full path, etc.
Only files whose type matches one of the file types passed in the filter will be displayed in the open file dialog box. The filter is a semicolon-separated list of file type names.įor example, if you wanted the user to be able to open only text files and postscript files when making a particular call to the ShowOpenFileDialog function, you would define two file types using either the File Type Sets Editor or the FileType class. The filter parameter is used to limit the types of files that the user can open to one or more of the file types defined via the FileType class or in the File Type Sets Editor in the IDE. The FolderItemDialog class has the same purpose but allows for some customization. The ShowOpenFileDialog function displays the standard open-file dialog box for the platform on which the application is running. Shows the standard Open File dialog box and returns the file as a folderitem selected by the user.
