Beautification of qtablewidget

Friendtable-> setframeshape (qframe: noframe); // you can specify a border.

Friendtable-> sethorizontalheaderlabels (headlist); set the header

Friendtable-> setselectionmode (q1_actitemview: singleselection); set the selected mode to single-Choice

Friendtable-> setselectionbehavior (q1_actitemview: selectrows); select a row each time when selecting behavior

Friendtable-> setshowgrid (false); Do not display grid lines

Friendtable-> setfont (font); set the font

Set form background or transparency

Qpalette pal = musictable-> palette ();
Pal. setbrush (this-> backgroundrole (), qbrush (qpixmap ("images/background.png ")));
Musictable-> setpalette (PAL );

Set the background image, or initialize the qbrush as qcolor to set the background color.

Qpalette PLL = musictable-> palette ();

PLL. setbrush (qpalette: Base, qbrush (qcolor (255,255,255, 0 )));

Musictable-> setpalette (PLL); // Like qtextedit, you can use the style sheet qpalette to modify its background color and background image. Here we set the brush to completely transparent, it can be transparent.

Set transparency Method 2:

Setstylesheet ("background-color: rgba (255,255,255,255)"); // The last parameter controls transparency.

How to add an image to the qtablewidget list
Qtablewidgetitem * cubesheaderitem = new qtablewidgetitem (TR ("cubes "));
Cubesheaderitem-> seticon (qicon (qpixmap ("1.png ")));
Cubesheaderitem-> settextalignment (QT: alignvcenter );
Musictable-> setitem (, cubesheaderitem); // display the image in the first column of the First row

* ******************* Modify the attributes of the header ****************

Musictable-> horizontalheader ()-> resizesection (0,150); // modify the width of the first column in the header to 150.

Musictable-> horizontalheader ()-> setfixedheight (25); // modify the appropriate height of the header

Musictable-> horizontalheader ()-> setstylesheet ("qheaderview: Section {background-color: lightblue; color: black; padding-left: 4px; Border: 1px solid # 6c6c6c ;} "); // set the header font, color, and mode.

Friendtable-> verticalheader ()-> setstylesheet ("qheaderview: Section {background-color: skyblue; color: black; padding-left: 4px; Border: 1px solid # 6c6c6c} "); // you can specify the font color mode of the border items in the column.

I was wondering if there were any existing APIs in QT, but the results were not found and I could only write them myself.
Qtablewidgetitem contains an API for modifying the background color, which can be called directly, and then used to change the color through loop control.
Implementation Code:
Void testtt: changecolor (qtablewidget * tablewidget ){
For (INT I = 0; I <tablewidget-> rowcount (); I ++)
{
If (I % 2 = 0)
{
For (Int J = 0; j <tablewidget-> columncount (); j ++)
{
Qtablewidgetitem * Item = tablewidget-> item (I, j );
If (item)
{
Const qcolor color = qcolor (1, 252,222,156 );
Item-> setbackgroundcolor (color );
}
}
}
}

Use

Insert an item to the table

Qtablewidgetitem * num = new qtablewidgetitem (qtablewidgetitem: type );
Num-> setcheckstate (QT: unchecked); // Add the check box
Num-> seticon (qicon ("images/fetion.png"); // Add the icon
Num-> settext (infolist. at (I). Name );
Num-> setfont (font );
Num-> settextcolor (color );
Num-> setflags (Num-> flags () ^ QT: itemiseditable );

Int currentrow = friendtable-> rowcount (); // insert to the end
Friendtable-> insertrow (currentrow );
Friendtable-> setitem (currentrow, 0, num); // insert this item
Friendtable-> selectrow (0); select the first row

Delete a row or column

Friendtable-> removerow (ROW );

Friendtable-> removecolumn (column );

Remove the default row number from QT qtablewidget.

The qtablewidget control automatically dragged out by qtoolbox contains its own row number. It sometimes needs to be removed. It was not found in this place last year. Today we found the relevant method and recorded it.

As shown above, the serial number is provided on the left by default at the beginning.

Qheaderview * headerview = table name-> verticalheader ();
Headerview-> sethidden (true );

Add the code above to remove the row number on the left.

Set the row's default height

Tablewidget-> verticalheader ()-> setdefasesectionsize (height)
