C#中如何实现先选择的pickfirst选择集按下ESC键清除选择集并且触发对Combobox
C#中如何实现先选择的pickfirst选择集按下ESC键清除选择集并且触发对Combobox控制内容列表清空，如下图所示：在Pycad里试了下，下面的代码是可行的
_esc = False
_num = 0
def pickfirst_added(ed, e):
if e.Flags == aced.SelectionFlags.PickfirstSet:
global _esc, _num
if _esc:
_esc = False
_num -= (e.Selection.Count + e.AddedObjects.Count)
else:
_num = e.Selection.Count + e.AddedObjects.Count
ed.WriteMessage("\n%s" % _num)
def pickfirst_removed(ed, e):
if e.Flags == aced.SelectionFlags.PickfirstSet:
global _num
_num = e.Selection.Count - e.RemovedObjects.Count
ed.WriteMessage("\n%s" % _num)
def on_message(sender, e):
m = e.Message
if (m.message == 0x0100) and (int(m.wParam) & 65535 == 27):
global _esc
_esc = True
@command()
def showpickfirstinfo(doc):
ed = doc.Editor#type: aced.Editor
ed.SelectionAdded += pickfirst_added
ed.SelectionRemoved += pickfirst_removed
acap.Core.Application.PreTranslateMessage += on_message
@command()
def unshowpickfirstinfo(doc):
ed = doc.Editor#type: aced.Editor
ed.SelectionAdded -= pickfirst_added
ed.SelectionRemoved -= pickfirst_removed
acap.Core.Application.PreTranslateMessage -= on_message 本帖最后由 雪山飞狐_lzh 于 2019-12-28 22:00 编辑
好吧 感觉我想多了。。。ImpliedSelectionChanged事件就可以 奇怪我昨天这样写怎么总不行？
def pickfirst_changed(sender, e):
#事件的触发者即当前文档
ed = sender.Editor#type: aced.Editor
#获取PickFirst选择集
res = ed.SelectImplied()
if res.Status == aced.PromptStatus.OK:
ed.WriteMessage(str(res.Value.Count))
else:
ed.WriteMessage("0")
def doc_created(sender, e):
#新文档创建后,绑定ImpliedSelectionChanged事件
e.Document.ImpliedSelectionChanged += pickfirst_changed
@command()
def showpickfirstinfo(doc):
#获取文档集合
docs = acap.Application.DocumentManager
#绑定DocumentCreated事件
docs.DocumentCreated += doc_created
for d in docs:
#遍历已有文档,绑定ImpliedSelectionChanged事件
d.ImpliedSelectionChanged += pickfirst_changed
@command()
def unshowpickfirstinfo(doc):
docs = acap.Application.DocumentManager
docs.DocumentCreated -= doc_created
for d in docs:
d.ImpliedSelectionChanged -= pickfirst_changed 用C#来写，这个不太明白 简单注释了一下。。。话说我觉得pycad的代码和C#相差不大
