推荐答案
查看 RichTextBox事件 [ ^ ]
GotFocus
事件就是您所需要的,但需要注意的是,当您从工具栏中单击保存按钮时,焦点将移动到此按钮。结论:您需要提供存储最后聚焦的RichTextBox信息的机制。
Have a look at the collection of RichTextBox events[^]
GotFocus
event is that what you need, but you need to be warned that when you click save button from toolbar, focus will be moved to this button. Conclusion: you need to provide mechanism to store information about lastly focused RichTextBox.
class Active
{
private string localfname=string.Empty;
private FastColoredTextBox localFctb;
public Active()
{
}
public string activeFile
{
get { return localfname; }
set { localfname = value; }
}
public FastColoredTextBox activeFctb
{
get { return localFctb; }
set { localFctb = value; }
}
}
1)将活动对象设置为另一个类作为属性。 />
2)每当按下工具栏按钮时,从活动类中获取活动对象。
1) "Set" active object to another class as a property.
2) "Get" active object from "Active Class" whenever toolbar button is pressed.
