Changing the color of a Push Button in QT Creator
提问by Aero Chocolate
How do I change a buttons color? I have found ways to do it by writing
如何更改按钮颜色？我找到了通过写作来做到这一点的方法
button->setStyleSheet("* { background-color: rgb(255,125,100) }");
in Ui_Window.h
在 Ui_Window.h
But everytime I qmake, the Ui_Window.h gets remade and I lose my colors.
但是每次我进行 qmake 时，Ui_Window.h 都会重新制作并且我失去了颜色。
Does anyone know how to permanently keep the colors of the button? I am working with QT Creator. If someone could direct me =D
有谁知道如何永久保持按钮的颜色？我正在与 QT Creator 合作。如果有人可以指导我 =D
Thanks so much!
非常感谢！

Easiest way would be to use a style sheet on the button:
backgroundColourButton->setStyleSheet("background-color: red");
最简单的方法是在按钮上使用样式表：
backgroundColourButton->setStyleSheet("background-color: red");

Aero, take into account that you MUST not modify Ui_Window.h file since it is generated by Qt Designer. So, every time you recompile the .ui file, this header file will be overwriten. As I see, you are using Qt Designer to add buttons to the layout. In this case, you can right click on a widget (or in the main dialog) in Qt Designer and click then in 'Change layout...'. On there, you can do something like:
Aero，请注意您不得修改 Ui_Window.h 文件，因为它是由 Qt Designer 生成的。所以，每次重新编译.ui 文件时，这个头文件都会被覆盖。如我所见，您正在使用 Qt Designer 向布局添加按钮。在这种情况下，您可以在 Qt 设计器中右键单击小部件（或在主对话框中），然后单击“更改布局...”。在那里，您可以执行以下操作：
QPushButton {
background-color: rgb(255,125,100);
}
for all buttons, or for an specific button:
对于所有按钮或特定按钮：
#nameOfTheButton {
background-color: rgb(255,125,100);
}
Tell me if this works for you. Cheers,
告诉我这是否适合你。干杯，

If you use your form only in one class, you may add your expression there, after calling to ui->setupUi()in it.
Or even add stylesheet directly to form, look for property 'StyleSheet' in properties view of Qt designer.
如果你只在一个类中使用你的表单，你可以在那里添加你的表达式，然后ui->setupUi()在里面调用。或者甚至直接将样式表添加到表单中，在 Qt 设计器的属性视图中查找属性“StyleSheet”。
