大家好,我希望用户选择文件列表(txt文件),我想在组框中显示这些文件的路径,我可以在c#中完美地做到这一点,但是c ++ \ cli出现了一些问题 我在Visual Studio 2017社区工作
这是我的代码:
openFileDialog1 = gcnew System::Windows::Forms::OpenFileDialog();
openFileDialog1->InitialDirectory = DefaultProgramPath;
openFileDialog1->FileName = "";
openFileDialog1->Filter = "ESA Files (*.esa)|*.esa|txt files (*.txt)|*.txt|All files (*.*)|*.*";
openFileDialog1->FilterIndex = 1;
openFileDialog1->RestoreDirectory = true;
if (openFileDialog1->ShowDialog() == System::Windows::Forms::DialogResult::OK)
{
String^ toBeAdded= openFileDialog1->FileName;
Label^job = gcnew Label();
job->Text = toBeAdded;
job->Location.X = 150;
job->Location.Y = 250;
groupBox1->Controls->Add(job);
}
使用此代码,标签被添加到了分组框,但我无法在其中正确设置其位置
感谢您的帮助
答案 0 :(得分:0)
System.Drawing.Point
是值类型(在C#中为struct
,在C ++ / CLI中为value class
/ value struct
),因此属性Location
返回的是< em>复制其当前位置。为了更新它,您需要立即设置整个值类型。
Point newLocation;
newLocation.X = 150;
newLocation.Y = 250;
job->Location = newLocation;
