在wxPython库中,`TimePickerCtrl`是用来创建一个用户界面元素,允许用户选择时间的控件。以下是基本的使用步骤:
1. 首先,你需要导入相关的模块:
```python
import wx
from wx.lib import datetimewidget as dtw
```
2. 在窗口初始化或布局过程中,添加`TimePickerCtrl`到面板上:
```python
class YourWindow(wx.Frame):
def __init__(self, *args, **kwds):
super().__init__(*args, **kwds)
self.pnl = wx.Panel(self)
# 创建时间选择器,并设置默认值
self.time_picker = dtw.TimePickerCtrl(self.pnl, style=wx.TE_PROCESS_ENTER)
self.time_picker.SetTimeNow() # 设置为当前时间
# 添加到面板布局
sizer = wx.BoxSizer(wx.VERTICAL)
sizer.Add(self.time_picker, proportion=1, flag=wx.EXPAND)
self.pnl.SetSizer(sizer)
```
3. 当用户选择时间并按下Enter键时,可以获取选中的时间,通常你会监听` EVT_TIME_CHANGED`事件:
```python
self.time_picker.Bind(dtw.EVT_TIME_CHANGED, self.on_time_changed)
def on_time_changed(self, event):
selected_time = self.time_picker.GetValue()
print(f"Selected time: {selected_time}")
```
4. 别忘了在`__exit__`方法中销毁控件:
```python
def __del__(self):
self.time_picker.Destroy()
```
