如何使用 KiCAD pcbnew 插件 Python API 获取所有选中的区域

在我们之前的文章中,我们展示了如何使用 KiCAD python API 获取所有选中的对象

get_current_selection.py
pcbnew.GetCurrentSelection()

你可以简单地过滤这些条目,使用带内联过滤的 for 循环获取仅选中区域的列表:

filter_selected_zones.py
for selected_object in pcbnew.GetCurrentSelection():
    if type(selected_object).__name__ == 'ZONE':
        print(selected_object.GetReference())

或使用列表推导:

selected_zones_listcomp.py
selected_footprints: list[pcbnew.FOOTPRINT] = [
    zone for zone in pcbnew.GetCurrentSelection() if type(zone).__name__ == 'ZONE'
]

完整插件示例:

simple_kicad_plugin.py
#!/usr/bin/env python
import pcbnew
import os

class SimplePlugin(pcbnew.ActionPlugin):
    def defaults(self):
        self.name = "Plugin Name as shown in Pcbnew: Tools->External Plugins"
        self.category = "A descriptive category name"
        self.description = "A description of the plugin and what it does"
        self.show_toolbar_button = False # Optional, defaults to False
        self.icon_file_name = os.path.join(os.path.dirname(__file__), 'simple_plugin.png') # Optional, defaults to ""

    def Run(self):
        board: pcbnew.BOARD = pcbnew.GetBoard()
        footprints: list[pcbnew.FOOTPRINT] = board.GetFootprints()

        # TODO Do something useful with [board]
        for selected_object in pcbnew.GetCurrentSelection():
            print(selected_object)

SimplePlugin().register() # Instantiate and register to Pcbnew

示例输出(节选):
