Common QT beautification

1. Add the background code of the window:

Qimage image1;

Image1.load (":/1.png"); // The relative directory of the image in parentheses

Qimage image2 = image1.scaled (320,240 );

Qpalette palette;

Palette. setbrush (this-> backgroundrole (), qbrush (image2 ));

This-> setpalette (palette );

Or

Qpalette palette;

Palette. setbrush (this-> backgroundrole (), qbrush (qpixmap (":/1png"); // The relative directory of the image in parentheses

This-> setpalette (palette );

 

2. Set the font size code:

Qfont font ("wenquanyi ",14);

Widget Object Name-> Setfont (Font);

Example: button-> setfont (Font);

 

3. Internationalization: in the main () functionW. Show ();Code prefix

Qtextcodec: setcodecfortr (qtextcodec: codecforname ("GBK "));

Qtextcodec: setcodecforlocale (qtextcodec: codecforname ("GBK "));

Qtextcodec: setcodecforcstrings (qtextcodec: codecforname ("GBK "));

 

4. Add an image for the Widget:

Method 1:

Widget Object Name-> Setstylesheet ("border-image: URL (:/1.png); "); // The relative directory of the image in parentheses

Method 2:

Widget Object Name-> Seticon (qicon (":/1.png"); // The relative directory of the image in parentheses

Widget Object Name-> Seticonsize (qsize (100,100); // you can specify the image size.

Method 3:

Widget Object Name-> Setstylesheet ("background-image: URL (:/1.png); "); // The relative directory of the image in parentheses

Observe the differences between the three methods through self-programming;
