c# gui programming tutorial

Recall that engaged in C + + development work for more than 4 years, mainly engaged in the development of Windows application based on MFC, Duilib and other GUI framework, also involved in some open source projects. But really talk about this language will be a little more or less guilty, about C + + understanding always feel one-sided and limited, there are some

point.So how do you make changes to the function variables? It's really simple, define a list, and then convert the list to tuples. The modified function is as follows:Def changeitems ():Tnames.append (' Java ')Cnames.set (Tuple (tnames))root = tkinter.tk ()Root.geometry (' +400+200 ')Root.minsize (400,200)Root.title ("Test")Tnames = [' Python ', ' TCL ', ' Ruby ']CNAMEs = Stringvar ()Cnames.set (Tuple (tnames))L = Listbox (root, listvariable = Cnames,height = ten). Grid ()Ttk. button (Root,tex

operation can continue to perform other tasks. When the operation is complete, his callback function is notified so that the program knows that the operation has ended NET4.5 already supports async and await, making async as easy as synchronizing programming. The purpose of the await keyword is to start a task that will be executed (the task will be executed in the new thread) and return immediately so that the function in which the await is located

It seems that I am doing a waste of time to invent the wheel-windows already has a very complex and functional GUI. unfortunately, Windows guis apply to office software, which is usually not suitable for game software. games generally require more accurate control than Windows (for example, it is easier to use your own GUI to implement a part of transparent windows created with Alpha mixture, while Windows
