## 1、Data Linkage
|
||||
[View](CityLinkage.py) | [Run](CityLinkage.py)
|
||||
|
||||
Three level linkage, data file is data.json
|
||||
|
||||
1. use `QComboBox`,`setModel` and `QSortFilterProxyModel` to filter
|
||||
2. the filter role is `Qt::ToolTipRole`
|
||||
3. can use `QColumnView` maybe like this example

# QComboBox
|

|

## 1、下拉数据关联
|
||||
[查看](CityLinkage.py) | [运行](CityLinkage.py)
|
||||
|
||||
一个省市区关联的三级联动，数据源在data.json中
|
||||
|
||||
1. 主要用了`QComboBox`的`setModel`设置一个`QSortFilterProxyModel`过滤模型
|
||||
2. 并根据唯一编码过滤，为了不影响内容显示，唯一编码的角色为`ToolTipRole`
|
||||
3. 用`QColumnView`可以实现类似效果

# 下拉框

## [1、QComboBox下拉数据关联](下拉选择联动)
|
||||
|
||||
这里简单的做了一个省市区关联的三级联动，数据源在data.json中
|
||||
|
||||
1. 主要用了`QComboBox`的`setModel`设置一个`QSortFilterProxyModel`过滤模型
|
||||
2. 并根据唯一编码过滤，为了不影响内容显示，唯一编码的角色为`ToolTipRole`
|
||||
3. 匆忙中写出来，可能有些不完善，或者该方式效率不是很高（后来发现可以用`QColumnView`实现）
