Description:

Spotifly is a C# winforms app whose primary functions are a Media player and an in-site Youtube downloader. To complement that it has a folder browser which filters the files to include only media files, more features later. There is also a media queue, you can add items to it and they will be played in the order that you have specified, about more features later. To let the user expand its media library, there is a page that lets users browse youtube, watch videos directly on youtube and download any video of any length as long as you have enough storage space. There is also a settings page, about all its features later.

To start diving deep lets see Form1.cs: There are some declared variables like an array of panels so they can be formatted to display to users and manipulated easier, a hash table to store plain text, settings and more! Form1 constructor: Then there is Form1 constructor where the Theme is changed a default directory is created if it doesn't exists, panels position and size is declared.

Form1_Load(): Panel[] is initialized and manually filled. hash table is also filled with all the necessary plain text. A PowerModeChange event is linked with the respective function so that when your pc sleeps the media is paused and a Stop Watch is initialized so when the function is almost finished a minWait of 600ms is waited. Then panels are moved and resized, folder browser is filled with media files and all the settings and previous session info is applied. Finally, update timer is started, more about that later.

Form1_FormClosing(): All settings get saved.

SetActivePanel(int panelIndex): A foreach loop starts and loop panel.Visible = current loop panel ReferenceEquals(panels[panelIndex]) Then BrowserBackButton and DownloadGroup .Visible fields are set whether panel index is the panel index of the browser page and whether if it isn't in homepage and if its in a video respectively.

SetFormSizeForCurrentMedia(): If user's settings are set to use this function, the function resizes the form so the media fills the whole media player given a minimum size

The rest of the file are page-changing buttons and MouseEnter / MouseLeave functions that change the color of a particular element on the form.
