lv_gui_designer is a drag-and-drop, simple GUI designer built with LittlevGL, and is based on pc_simulator_sdl_eclipse. Its interface is built with LittlevGL.
- 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_mainto your code.(Doing)
Select a parent for a widget:
Load XML File to live-demo(Beta), try to write some tags <CONTAINER><BTN><LABEL><ARC><DDLIST>, etcto design your GUI:
lv_gui_designer is very dependent on LittlevGL v6.0:
- USE EVENT
- Three parts: Creator, Simulator, Setting, just three
lv_winobject. - 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.
- Git clone the project.
- cd into the folder, and make (Linux is fine)
- run ./lv_gui_designer
