![]() View the call stack using the Stack window ( View | Stack Window), Inspect variables using the Watch window ( View | Watch Window), Step through the code (using Project | Step Into, Project | Step Over, and Project | Step Out commands), When the debugger is stopped, you can set/remove breakpoints (using Project | Toggle Breakpoint), When your program is running, you can pause it by going to Project | Break, which will stop your program at the next lua command executed. To start debugging go to Project | Start Debugging.ĭepending on your interpreter configuration, the debugger may stop your program on the first instruction (this is a default for most interpreters) or may execute it immediately (as configured for Moai and Corona interpreters). It uses the composable Canvas with the modifier property pointerInteropFilter which is used to detect down and upward movement of the path across the XY fun ScratchPad() įinally, your MainActivity should look like this.The debugger allows to execute Lua scripts and applications step by step, pause them, inspect variables, evaluate expressions, make changes to variables, and then continue execution. Using the states of path color and brush it can detect movements from current to the next state. The last composable used is drawing Canvas which is used to listen to all the movements. The composable uses the path of type PathState to listen to all the drawings done on the screen. The paint body is used to define all the components used in drawing, that is the drawing canvas and drawing tool all placed in a layout box. Let us dive deeper into each composable used.Ī TopAppBar composable is used to create the app bar with the app name and an icon which is used for deleting errors. ![]() There are several composables used to create a scratchpad. Step 4 - Creating a scratchpad in the main activity ![]() Path state is a data class that holds the variables path, color, and stroke used in the implementation of the scratchpad. Initially, we talked about the path and said, the path is a Jetpack compose class that is used in conjunction with canvas to show compound geometric pathways made up of straight-line segments, quadratic curves, and cubic curves. The brush thickness is arranged in a column and it is given an animation property when the fab is clicked. The floating action button provides a way to choose brush thickness. This composable gives the capability to choose the color of interest when drawing and also gives the ability to apply the color to the text. All elements are arranged in a common layout that is the column. The drawing tool is a composable that comprises drawing color, brush and all components to be used in drawing. Kotlin is selected automatically as the language to be used, click OK after giving the project a suitable name. Choose an empty compose activity and click Next. To create a new project with the Android Studio IDE, go to File > New > New Project. Let’s create an application where users can draw sketches just like how a scratchpad works.
