我想知道在TForm中嵌入和控制MS Word的建议方法是什么?目前,我(1)在TForm上放了两个TPanel。 alBottom
TPanel有一个TButton,alClient
TPanel有alNone
个TOleContainer。 (2)在TMainForm.FormCreate事件处理程序中设置布局。
问题是MS Word喜欢占用其父表单的所有空间。只有如下所示的第四种方式似乎给出了可接受的布局。基于反复试验,似乎有必要使用子表单而不是TPanel来托管TOleContainer。 (另外,Windows.SetParent似乎是必要的。)我想知道子表单是否是正确的方法?

答案 0 :(得分:1)
子表单是一种正确的方法。我们在生产环境中使用这种方法并且它起作用。我们在一个小组中托管了我们的“子”表格。但是,我们使用标志修改了TOleContainer和TOleForm,无论是使用父窗体还是最顶层窗体:
procedure TOurOleContainer.InitObject;
...
begin
if FDrawInTopForm then
DocForm := GetParentForm(Self)
else
DocForm := TCustomForm(Parent);
...
FDrawInTopForm是我们介绍的属性。我们还修改了:
function GetVCLFrameForm(Form: TCustomForm; DrawInTopForm: Boolean): IVCLFrameForm;
begin
if Form.OleFormObject = nil then TOleForm.Create(Form, DrawInTopForm);
Result := Form.OleFormObject as IVCLFrameForm;
end;
