QT style syntax definition access, can check the data, can be automatically generated

background ：

Spreadsheets are packaged in the project QTableWidget, Because when the focus is lost in the selected state , The selected cell turns gray , As a result, the background color and text of the selected state cannot be seen clearly . So check the method online .

It can be implemented directly with style like a web page , So he added such a sentence ：

setStyleSheet("selection-background-color:lightblue;selection-color:black;");

When I first wrote , I only know how to use setStyleSheet Function implementation , But the specific writing method of the style is not only known , Just rely on the previous front-end pair css Understanding , Specifies the background color . The following sentence specifies the font color , It was not written at first , I use it font-color, I don't know , Is tantamount to blind testing .

At the same time, I saw some questions on the Internet , How to get the definition and description of specific style syntax .

Method ：

According to my experience , First of all, you should be familiar with the front end css grammar , There is a lot of information on this , Any relatively perfect document is enough . But for reference only . because qt Whether the style in is and css Exactly the same , I have no research on this , I didn't check the relevant information .

Another way is to use qt creator The designer of , It can generate style statements by itself , Make any form , Right click to modify the style , It will automatically generate style statements . For example, take the table as an example , Put one on the form QTableWidget parts , Right click on it ：

choice “ Change the style sheet ”.

 

Choose... As you like , It will generate statements .

 

  They all write programs , As long as you know the grammar , The rest is easy to do , How to express the specific value is easy .
