![]() ![]() Questions? Ask me about Xojo programming on Twitter or on the Xojo Forum. While the Window1 window remains open, our file will be available in the Desktop but as soon we close the Window1 window… the file will be deleted automatically! The plugin MBS XML Plugin: class XMLAttributeMBS. ![]() Run the example project and see how it works. Xojo Plug-ins Platforms to show: All Mac Windows Linux Cross-Platform. Also the underlying FolderItem stored on it via the Destructor method of our class will be deleted. Once we close the window, everything will be destroyed from memory, including this property. This way, the TempFolderItem will be in Scope (this is, in memory) while the Window1 window remains opened. Next add a new Property to the default window ( Window1) using the following values in the Panel Inspector: Var tos As TextOutputStream = TextOutputStream.Open(f) That’s all – our class definition is done! In order to test it, create a Desktop project, add the Open Event Handler to the default window and write this snippet of code in the Code Editor: Const textContent As String = "Lorem ipsum dolor sit amet, consectetur adipiscing elit"į = New TempFolderItem(("Test.txt")) If mfile Nil And mfile.Exists And mfile.IsWriteable ThenĮnd Try Temporary FolderItems in Practice This one will be in charge of deleting the underlaying FolderItem once the class instance is out of scope: Then, we need to add a couple of Operator_Convert methods:įinally, we will add the Destructor method. Next, let’s add a Constructor method to our class with the following signature:Īnd simply put this line of code in the associated Code Editor: mFile = f We can name it as TempFolderItem with an empty Super class in the Inspector Panel.Īdd a new property to the new TempFolderItem class, using the following values in the Inspector Panel: In order to instruct a FolderItem to delete itself when it’s out of scope, we will create a new class that will act as a wrapper for the FolderItem, making use of the Operator_Convert method, so we can assign a FolderItem to it and also get the underlying FolderItem wrapped in it. Wouldn’t it be great to automate that task? Continue reading and you’ll see how easy it is to implement this! Sometimes we need to deal with temporary FolderItem instances, and in those cases it would be great to not have to care about when they get out of scope in order to delete them. ![]()
