pyRevit WPF 非模态问题
pyRevit WPF non-modal trouble
所以我才刚刚开始接触 pyRevit 中的 WPF。我试图像这样实现 pyrevit.forms.WPFWindow Class：
# -*- coding: UTF-8 -*-

pyRevit: repository at https://github.com/eirannejad/pyRevit
"""
import System, clr, json, sys
clr.AddReference("System.Windows.Forms")
clr.AddReference('IronPython.Wpf')
import wpf
from Autodesk.Revit.DB import *
from pyrevit import revit, script, forms
class FactorySettings(forms.WPFWindow):
def __init__(self):
forms.WPFWindow.__init__(self, script.get_bundle_file('settings.xaml'))
def something_click(self, A, B):
plantings = FilteredElementCollector(revit.doc) \
.WhereElementIsElementType() \
.OfCategory(BuiltInCategory.OST_Planting)
ui = FactorySettings()
ui.show()
这是我的 xaml:
<Window xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:sys="clr-namespace:System;assembly=mscorlib"
xmlns:Collections="clr-namespace:System.Collections;assembly=mscorlib"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
mc:Ignorable="d"
ShowInTaskbar="False" ResizeMode="CanResize"
WindowStartupLocation="CenterScreen"
HorizontalContentAlignment="Center"
Title="Set worksets" Width="300" SizeToContent="Height"
>
<StackPanel Margin="0,0,0,0" VerticalAlignment="Stretch" HorizontalAlignment="Stretch">
<Button Content="Do something" Name="something" Click="something_click"/>
</StackPanel>
</Window>
由于 def show(self, modal=False): class 函数，这将打开一个非模态 window。
我的问题是，即使我的点击功能只调用 FilteredElementCollector 对象，Revit 也会崩溃。如果我这样做 ui.show(modal=True) 它会工作，但我无法在 Revit UI 中做任何事情。
我真正想要的是这样做：
def something_click(self, A, B):
if self.PHfamSymbol != None:
with forms.WarningBar(title='Place an instance of the placeholder object.'):
revit.uidoc.PromptForFamilyInstancePlacement(self.PHfamSymbol)
这将不起作用，因为焦点仍在 UI 上。
我试过这个：
def something_click(self, A, B):
if self.PHfamSymbol != None:
self.Close()
with forms.WarningBar(title='Place an instance of the placeholder object.'):
try:
revit.uidoc.PromptForFamilyInstancePlacement(self.PHfamSymbol)
except:
pass
这可行，但我需要在完成后创建 UI 的新实例。
是否有可能在 pyRevit 中使用非模态 UI？
你需要使用一个ExternalEvent to interact with Revit in a non modal windows. You have many samples in pyRevitMEP. I made a reusable class here. I use it in many pyRevitMEP script like Element3DRotation. You can also check my old blog [Revit API] Simple Modeless Form (External Event Handler) in pyRevit post 引用更多的资源和更多的评论。
