How to hide QLabel by default in QtDesigner

Question

I've been working on project in Visual Studio and QtDesigner.
I want to set QLabel(pixel, mm) be invisible by default. Someone have any idea ?

Answer 1

It is not possible to set QWidget visible-property in QtDesigner, see this question : Initially hidden control in Qt Creator .

You need to do this through the code, in your parent constructor after initializing the UI objects:

ui->setupUi(this);
[...]
ui->myLabel->setVisible(false);

Answer 2

您无法控制visible属性，但是如果要使QLabel默认为不可见，只需将width/height属性设置为0 。
