Weifenluo dockpanel套房：嵌入tabcontrol&隐藏浮动表格 [英] Weifenluo dockpanel suite: embed into tabcontrol & hide floating forms

问题描述

我是DockPanel Suite的新手。

我想要实现的是，在Winforms的TabControl中使用Dockpanel组件（使用DocumentStyle = DockingMdi）。

如果我将DocumentStyle设置为DockingWindow或DockingSdi它工作正常，但更少的对接选项

I am new to DockPanel Suite.
what i'm trying to achieve is, having Dockpanel component(with DocumentStyle = DockingMdi) within a TabControl in Winforms.
If i set DocumentStyle to DockingWindow or DockingSdi it works fine, but fewer docking options

SecondForm ^SF = gcnew SecondForm ();
SF->Show(dockPanel1, DockState::Document);

将DocumentStyle设置为DockingMdi我收到运行时错误



WeifenLuo.WinFormsUI.Docking.dll中发生未处理的System.InvalidOperationException类型异常

其他信息：无效父母表格。使用DockingMdi或SystemMdi文档样式时，DockPanel控件必须是主MDI容器窗体的子控件。



i added mf-> Parent =这个;在SF-> Show（）之上，我得到一个新的运行时错误说



System.Windows中发生类型为'System.ArgumentException'的未处理异常.Forms.dll

附加信息：顶级控件无法添加到控件中。



我的第二个查询是，如何隐藏浮动表单？

如果所有表单都停靠在DockPanel中，则隐藏功能运行良好，

如果我调用dockpanel1->隐藏（）;在制作一个浮动形式之后，浮动形式除外，其他一切都将被隐藏

应该有一些解决方法。请分享您的想法



谢谢



我的尝试：



在tabcontrol外放置dockpanel使其工作（DocumentStyle设置为DockingMdi）

setting DocumentStyle to DockingMdi i get an runtime error

An unhandled exception of type 'System.InvalidOperationException' occurred in WeifenLuo.WinFormsUI.Docking.dll
Additional information: Invalid parent form. When using DockingMdi or SystemMdi document style, the DockPanel control must be the child control of the main MDI container form.

i added mf->Parent = this; above SF->Show(), i get a new runtime error saying

An unhandled exception of type 'System.ArgumentException' occurred in System.Windows.Forms.dll
Additional information: Top-level control cannot be added to a control.

My second query is, How to hide floating forms?
if all forms are docked in DockPanel, hide function works well,
if i call dockpanel1->Hide(); after making one form float, except floating form, everything else will be hidden
there should be some workaround for this. please share your thoughts

Thanks

What I have tried:

placing dockpanel outside tabcontrol makes it work (with DocumentStyle set to DockingMdi)

推荐答案

TabControl是一个容器控制不能有顶级控制或MDI（包含多种形式），所以控件不允许你想要做的事情..



第二个问题回答： -

首先找到你的表格然后隐藏表格..

代码是： -

TabControl is a container control which can not have top level control or MDI(which contain multiple forms), so what you are trying to do is not allowed by the control..

Second question's answer:-
first find your form then hide the form..
code is:-

Form childFrm = this.MdiChildren.First(frm => frm.Name.Equals("findFormName"));
            if (childFrm != null)
            {
                childFrm.Hide();
            }

我希望这会对你有帮助..

I hope this will help you..

我希望这可以帮助有相同问题的人。 dockPanel1 = nullptr; 在这种情况下无效。使用下面的代码，我们可以安全地从dockPanel中删除内容。

I Hope this helps someone with same issue. dockPanel1 = nullptr; doesn't help in this case. using below code,we can safely remove contents from dockPanel.

if (dockPanel1->DocumentStyle == DocumentStyle::SystemMdi)
	{
		for each(Form ^form in MdiChildren)
			form->Close();
	}
	else
	{
		for (int index = dockPanel1->Contents->Count - 1; index >= 0; index--)
		{
		 if (dynamic_cast<idockcontent^>(dockPanel1->Contents[index]) != nullptr)
		 {
          IDockContent ^content = safe_cast<idockcontent^>(dockPanel1->Contents[index]);
		  content->DockHandler->Close();
		 }
		}
	}
