我有一个QTableWidget,2列,其中第一列包含项目名称,而第二列填充qcomboboxes(使用cellwidgets创建),其中包含颜色选项列表(例如“”,RED,BLUE, GREEN)
例如,在下表中,用*表示的项目有一个名为color_set
的变量,我试图实现如下:
shirt_01
包含一个名为color_set
此函数/值在ui启动之前用信息填充表,它不是按钮单击功能等。
Name of items | Color Options
shirt_01* | RED
shirt_02 |
pants* | GREEN
然而,我得到的结果如下:
,而不是让我的ui输出如上所示 Name of items | Color Options
shirt_01* | RED
shirt_02 | RED
pants* | GREEN
由于某些原因,shirt_02
似乎“纠结”并显示与shirt_01
相同的结果。而且我认为这可能是由于我的逻辑是如何编写的,但是我无法理解它,或者因为我的输出结果一直在self.color_combobox
,因为我的代码最初通过第一列检查然后找到匹配的文本第二栏。
但是我一直在行中出错 - item_name没有属性.text()

无论如何,我可以让我的ui检查场景中的项目列表,标记它应该去哪个名称和组合框(根据哪些行/列)?否则我还能采取其他方式吗?
编辑:这是我快速完成的附件 - Link 如果您运行UI,您会注意到pCube1的颜色为“红色”,而pCube2为“蓝色”,但两个组合框都会变为蓝色而不是

如果颜色变量不存在,您的代码需要将颜色组合显式设置为空白项:
def populate_data(self):
geo_name = self.all_mesh
for row_index, geo_item in enumerate(geo_name):
new_item = QtGui.QTableWidgetItem(geo_item)
# Add in each and every mesh found in scene and append them into rows
self.mesh_table.setItem(row_index, 0, new_item)
geo_exclude_num = ''.join(i for i in geo_item if not i.isdigit())
color_list = read_json(geo_exclude_num)
color_list.add("")
# Insert in the color
color_combobox = QtGui.QComboBox()
#color_list = get_color()
color_combobox.addItems(list(sorted(color_list)))
self.mesh_table.setCellWidget(row_index, 1, color_combobox)
# This attribute is stored in the Extra Attributes
objAttr = '%s.pyPickle' % geo_item
storedData = attrToPy(objAttr)
if 'color_set' in storedData:
color_variant = storedData['color_set']
else:
color_variant = ''
combo_index = color_combobox.findText(color_variant, QtCore.Qt.MatchFixedString)
color_combobox.setCurrentIndex(0 if combo_index < 0 else combo_index)
(注意:为了使其正常工作,您显然必须确保组合框中的第一个条目是空白项目。)

好的,问题发生在color_value_to_combobox
。您需要指定函数需要处理的对象和组合框,而不是为所有对象设置组合框。主要的缺陷是你每次都使用self.color_combobox
设置,所以每个对象都会保持设置相同的组合框!它需要更通用。
无论如何,我只需要更改populate_data
和color_value_to_combobox
的结尾。现在cube1
显示red
,cube2
显示blue
。

如果你查看你发布的代码,它不显示行上的循环以将组合框放在每个单元格中,但我会假设有一个,否则它根本不起作用。
你应该做的是两件事之一: - 如果你有一个单独的循环来创建组合框,那么在该循环中如果项目没有颜色则不创建组合框;然后在第二个循环中检查单元格是否有一个组合框,并且只有在确定它是否配置它时。 - 第二个选项是将第一个循环移动到行循环中,即您循环通过每一行确定项目是否有颜色,并且只有在它确定的情况下,您是否创建组合框并进行配置;如果没有颜色,那就把那个卖空了。
