由于System.Windows.Forms
的形式继承自Control,我想知道是否有办法创建自定义表单及其设计器,其中包含一些选项(快捷方式)来创建标题或类似的东西。
试过这个,但什么也没发生,我称之为ManagedForm
[Designer(typeof(ManagedFormDesigner))]
public class ManagedForm : Form{
//code here
}
[PermissionSet(System.Security.Permissions.SecurityAction.Demand, Name = "FullTrust")]
public class ManagedFormDesigner : ControlDesigner {
private DesignerActionListCollection actionLists;
public override DesignerActionListCollection ActionLists {
get {
if (actionLists == null) {
actionLists = new DesignerActionListCollection();
actionLists.Add(new ManagedFormDesignerActionList(this.Component));
}
return actionLists;
}
}
}
public class ManagedFormDesignerActionList : DesignerActionList {
private ManagedForm managedForm = null;
private DesignerActionUIService designerActionUISvc = null;
public ManagedFormDesignerActionList(IComponent component) : base(component) {
this.managedForm = component as ManagedForm;
this.designerActionUISvc =
GetService(typeof(DesignerActionUIService))
as DesignerActionUIService;
}
public override DesignerActionItemCollection GetSortedActionItems() {
DesignerActionItemCollection items = new DesignerActionItemCollection();
items.Add(new DesignerActionMethodItem(this, "CreateTitle", "Create Title", "Appearence", true));
return items;
}
public void CreateTitle() {
Panel pTitulo = new Panel();
pTitulo.Size= new Size(100,25);
pTitulo.Dock = DockStyle.Top;
(this.Component as ManagedForm).Controls.Add(pTitulo);
}
}
窗体内控件上的小箭头时显示操作列表(如果对象是组件,则单击设计器底部的组件)。
您可以做的其他事情是管理动词。谓词处理是在 ControlDesigner 类(在您的例子中为 ManagedFormDesigner)上实现的。您可以看到动词单击鼠标右键或在属性底部(即 TabControl ha 2 个动词,添加制表符和删除制表符)。
你可以实现动词添加到ControlDesigner(或ComponentDesigner)类,
如下所示 private DesignerVerbCollection _verbs;
public override DesignerVerbCollection Verbs
{
get
{
if (_verbs == null)
{
_verbs = new DesignerVerbCollection();
_verbs.Add(new DesignerVerb("Create Title", new EventHandler(MyCreateTitleHandler)));
}
return _verbs;
}
}
private void MyCreateTitleHandler(object sender, EventArgs e)
{
// Do here something but take care to show things via IUIService service
IUIService uiService = GetService(typeof(IUIService)) as IUIService;
}
