我创建了一个组件,当在设计时双击它时,它会创建另一个表单。代码如下:
function TMyComponentTest1.Execute: Boolean;
var
Form: TMyComponentTest1Form;
begin
try
Form := TMyComponentTest1Form.Create (nil);
Form.ShowModal;
finally
Form.Free;
end;
end;
在这个新形式中,我必须获得主要设计形式的组件,但我不能这样做,有没有人知道我如何能够实现这一目标? 我也尝试使用“self”进行创建,但是当我双击它时,delphi会崩溃......

以下是我认为可以使用的一些未经测试的代码。让我们将您的组件称为TMyComponent。您必须在TMyComponent的designtime包中创建TMyComponentTest1Form,作为组件编辑器和/或属性编辑器的一部分。
然后,尝试像这样创建TMyComponentTest1Form:
function TMyComponentTest1.Execute: Boolean;
var
aForm: TMyComponentTest1Form;
OwnerForm: TForm;
aMyComponent: TMyComponent;
begin
{OwnerForm is your main design form}
OwnerForm := nil;
{Get your component on the main design form}
aMyComponent := TMyComponent(GetComponent(0))
{Make sure your component's owner is a TForm}
if (aMyComponent.Owner is TForm) then
OwnerForm := TForm(aMyComponent.Owner);
{You problem may be solved by making component form owner the Application}
aForm := TMyComponentTest1Form.Create(Application);
try
{
Now you should be able iterate the components owned by OwnerForm
right here. If you do not want to do it here, add a TForm property
to your component and assign OwnerForm to it.
}
aForm.ShowModal;
finally
aForm.Free;
end;
end;
