Qt 4 QComboBox弹出菜单边距样式
经过无数个小时尝试设计 QComboBox 的样式后,我被插入项目的顶部和底部边距所困扰。
我想删除或应用背景颜色到弹出菜单顶部和底部空白。

我添加了一个最小高度QListView 不显示顶部和底部箭头。我还查看了 Qt 源代码中的 QComboBoxPrivate 类,但似乎顶部和底部边距是硬编码的。
感谢您的帮助。
编辑:这是到目前为止我的样式表
QComboBox {
border: 1px solid rgb(95, 95, 95);
border-radius: 3px;
padding: 1px 18px 1px 3px;
min-width: 6em;
color: rgb(220, 220, 220);
background-color: rgb(80, 80, 80);
margin: 0 0 0 0;
}
QComboBox:editable {
background: rgb(80, 80, 80);
}
QComboBox:!editable {
background: qlineargradient(x1: 0, y1: 0, x2: 0, y2: 1,
stop: 0 rgb(51, 51, 51), stop: 0.4 rgb(39, 39, 39),
stop: 0.5 rgb(32,32,32), stop: 1.0 rgb(38,38,38));;
}
QComboBox::drop-down:editable {
}
QComboBox:!editable:on {
}
QComboBox::drop-down:editable:on {
}
QComboBox:on { /* shift the text when the popup opens */
padding-top: 3px;
padding-left: 4px;
background-color: rgb(80, 80, 80);
}
QComboBox::drop-down {
subcontrol-origin: padding;
subcontrol-position: center right;
width: 15px;
right:3px;
border-top-right-radius: 3px; /* same radius as the QComboBox */
border-bottom-right-radius: 3px;
background:none;
}
QComboBox::down-arrow {
image: url(:/images/arrow-down-inverted.png);
height: 10px;
}
QComboBox::down-arrow:on { /* shift the arrow when popup is open */
top: 1px;
left: 1px;
}
QListView#comboListView {
background: rgb(80, 80, 80);
color: rgb(220, 220, 220);
min-height: 90px;
margin: 0 0 0 0;
}
QListView#comboListView::item {
background-color: rgb(80, 80, 80);
}
QListView#comboListView::item:hover {
background-color: rgb(95, 95, 95);
}
After countless hours trying to style a QComboBox, I'm stuck with the top and bottom margin where the items are inserted.
I would like to either remove or apply a background-color to the popup menu top and bottom white spaces.

I added a min-height to the QListView not to show top and bottom arrows. I also looked at the QComboBoxPrivate class in Qt sources but it seems that the top and bottom margins are hardcoded.
Thanks for your help.
Edited: This is my stylesheet so far
QComboBox {
border: 1px solid rgb(95, 95, 95);
border-radius: 3px;
padding: 1px 18px 1px 3px;
min-width: 6em;

background-color: rgb(80, 80, 80);
margin: 0 0 0 0;
}
QComboBox:editable {
background: rgb(80, 80, 80);
}
QComboBox:!editable {
background: qlineargradient(x1: 0, y1: 0, x2: 0, y2: 1,
stop: 0 rgb(51, 51, 51), stop: 0.4 rgb(39, 39, 39),
stop: 0.5 rgb(32,32,32), stop: 1.0 rgb(38,38,38));;
}
QComboBox::drop-down:editable {

您需要在
QComboBox
中自定义QAbstractItemView
:You need to customize the
QAbstractItemView
in theQComboBox
:尝试以下样式表:
这应该将边距设置为 0。另外此处 是对样式表的 qt 引用。
Try the following stylesheet:
This should set the margins to 0. Also here is a qt reference to the stylesheets.
我发现删除白边的解决方案是将组合框设置为只读。
The solution I found to remove the white margin is to set the combobox to read-only.
