Here is a screenshot of &kturtle; in action &kturtle; Main Window The main window of &kturtle; has three main parts: the editor (1) on the left where you type the &turtlescript; commands, the the canvas (2) on the right where the turtle make your drawing, and the inspector (3) which gives you information when your program executes. Besides these you find the menu bar (5) from where all the actions can be reached, the toolbar (4) that allows you to quickly select the most used actions, the Console, that you can use to enter a one line command to test it, and the statusbar (along the bottom of the window) where you will find feedback on the state of &kturtle;. In the editor you type the &turtlescript; commands. Most of functions of the editor can be found in the File and Edit menus. The editor can be docked on each border of the main window or it can be detached and placed anywhere on your desktop. You have several ways to get some code in the editor. The easiest way is to use an example: choose FileExamples in the File menu and select an example. The file example you choose will be opened in the the editor, you can then use RunRun from the menubar or the Run from the toolbar to run the code if you like. You can open &turtlescript; files by choosing FileOpen.... The third way is to directly type your own code in the editor or to copy/paste some code. The canvas is the domain of the turtle, here the turtle draws according to the commands it gets. After getting some code in the Editor and executing it, two things can happen: either the code executes fine, and will you most likely see something change on the canvas; or you have made an error in your code in that case the error tab will appear explaining you what mistake you made. You can zoom in and out the canvas with your mouse wheel. The inspector informs you about the variables, the learned functions and show the code tree while the program is running. The inspector can be docked on each border of the main window or it can be detached and placed anywhere on your desktop. Here you can quickly reach the most used actions. The Toolbar also contains the Console where you can quickly invoke commands, this might be useful in case you want to test a command without modifying the content of the Editor. You can configure the toolbar using SettingsConfigure Toolbars... to better fit your preferences. In the menubar you find all the actions of &kturtle;. They are in the following groups: File, Edit, Canvas, Run, Tools, Settings, and Help. This section describes them all. &Ctrl;N File New Creates a new, empty &turtlescript; file. &Ctrl;O File Open...

F5 Run Run Starts the execution of the commands in the editor. F6 Run Pause Pauses the execution. This action is only enabled when the commands are actually executing. F7 Run Abort Stops the execution. This action is only enabled when the commands are actually executing. Run Run Speed Present a list of possible execution speeds, consisting of: Full Speed, Slow, Slower, Slowest and Step-by-Step. When the execution speed is set to Full Speed (default) we can barely keep up with what is happening. Sometimes this behavior is wanted, but sometimes we want to keep track of the execution. In the latter case you want to set the execution speed to Slow, Slower or Slowest. When one of the slow modes is selected the current position of the executor will be shown in the editor. Step-by-Step will execute one command at a time. Tools Direction Chooser... This action opens the direction chooser dialog. Tools Color Picker... This action opens the color picker dialog. SettingsScript Language Choose the language for the code. &Ctrl;E Settings Show Editor Show or hide the Editor. &Ctrl;I Settings Show Inspector Show or hide the inspector. Settings Show Errors Show or hide the Error tab with a list of errors resulting from running the code. If this option is enabled, click on Canvas to see the turtle again. F11 View Show Line Numbers With this action you can show the line numbers in the editor. This can be handy for finding errors. SettingsShow Toolbar Toggle the Main Toolbar SettingsShow Statusbar Toggle the Statusbar Settings Configure Shortcuts... Standard &kde; dialog to configure the shortcuts. Settings Configure Toolbars... The standard &kde; dialog for configuring the toolbars. &help.menu.documentation; F2 Help Help on: ... This is a very useful function: it provides help on the code where the cursor in the editor is at. So, ⪚, you have used the print command in your code, and you want to read and to know what the handbook says on this command. You just move your cursor so it is in the print command and you press F2. The handbook will then show all info on the print command. This function can prove to be useful while learning &turtlescript;. On the status bar you get feedback of the state of &kturtle;. On the left side it shows the feedback on the last action. On the right side you find the current location of the cursor (line and column numbers). In the middle of the status bar is indicated the current language used for the commands.
