## What is lv_gui_designer?

lv_gui_designer is a drag-and-drop, simple GUI designer built with LittlevGL, and is based on [pc_simulator_sdl_eclipse](https://github.com/littlevgl/pc_simulator_sdl_eclipse). Its interface is built with LittlevGL.

## Feature

* Create object based on an object, Parent-child structure(In test, now if you want to create a obj, you need to choose a parent in layerview).

* Drag and drop to control the postion of the widget.

* TFT_simulator can be customized(size), supports mutiple windows.(To do)

* Modfied attribute(postion, size, click, etc) and style. (Doing)

* Save project in XML format, project can be loaded as live-demo. 

* XML can be converted to C and Python: includes GUI and Callback. Just add a function `lv_gui_main` to your code.(Doing)

## Screenshot

Select a parent for a widget:

## How it works?

lv_gui_designer is very dependent on LittlevGL v6.0:

* USE [EVENT](https://docs.littlevgl.com/en/html/overview/event.html)

* Three parts: Creator, Simulator, Setting, just three `lv_win` object.

* Creator: Select what widget you want to create at Simulator, and the widget will enable "drag" (lv_obj_set_drag & lv_obj_set_drag_parent), so we can drag-and-drop it. 

* Simulator: Only its child can be drag-and-drop, its grandchild is not a drag-able widget, for example, there are a Button on the Simulator with a Label, due to Button is a auto-align Container, Label will be sticked to Button's centre. Every widget on there has a callback function to transport some information to Settting.

* Setting: Select a widget on Simulator by LayerView, we can create a new son-widget on it and change its attribute, style, animation, we can delete it. 

## Get Start
