How can realize the control of style in Qt QSS updated?-CodePudding

Masters, you ask a question, how can realize control style update in QSS?

For example, an application scenario has the following:
A QLineEdit input box:
When focus after losing, would be to check whether meet the requirements, if do not conform to, change this input box color style such as:

QSS is as follows:

 
/* -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- QLineEdit -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- - */
QLineEdit {border: # 1 px solid DDD; width:100%; font-size:14px; height:24px; line-height:24px; Padding: 4 px; } 
QLineEdit {border: 1 px solid # BBB; } 
QLineEdit {border: 1.3 px solid # 3 bb4f2; } 
QLineEdit: disabled, QLineEdit: disabled: focus {background - color: # ededed; Border - color: # DDD; } 
//////////this is where the key 
QLineEdit: if it is wrong to {background - color: # fbe2e2; Border - color: # c66161; Color: # c00; }

Question: how should the writing mistakes in QSS that logo? How to reflect the style in the program? At the same time, after the input correctly, how to return to normal QLineEdit style?

Online, etc., thank you

thank you for your reply,
QLineEdit how to judge whether your input, this need your own judgment, is not in conformity with all you have to do is to set up lineEdit QSS

How to determine the I is relatively easy to implement, but how to reset? I hope that after a reset style is to write in the QSS

Assistance with speaking,

Hello:
I saw you for the manual document, but I still didn't finish:
Now I for style set an attribute:
QLineEdit [stated="true"] {background - color: # fbe2e2; Border - color: # c66161; Color: # c00}

If the program start loading, I set the setProperty (" stated ", true); , then the control will display this kind of style,
But if initially QLineEdit stated attribute is false, and then I by clicking on the button after setting stated=true; Is the control no reaction,
Is excuse me this why? I should be a less, operation, trouble you,

Can be set against the ObjectName QSS:
LineEdit. SetObjectName (' normal ')
-- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
QSS file:
QLineEdit# normal {background:... ; }
QLineEdit# error {background:... ; }
-- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
Judgment for the mistake, set the
LineEdit. SetObjectName (' error ')

But I didn't try, you can not try this...
