I have a QMenu in a QMenuBar.
I can make the QMenu appear via QMenu.show() QMenu.exec() and QMenu.showTearOffMenu(), but these show the menu at the top-left of the screen, at a prespecified position, or under the mouse. I want the menu to appear in its usual position (under the QMenuBar). Is this possible (in any Qt language)?
答案 0 :(得分：1)
你可以简单地使用
$fa-font-path: "font-awesome/fonts" !default;
@import 'font-awesome/scss/font-awesome';
其中self将对应于QMainWindow
参考 setMenuBar
将主窗口的菜单栏设置为menuBar。

在Qt中，您可以使用菜单栏的位置，然后打开该位置的菜单：
$(function() {
var chartChartColumnRangeRate;
var chartChartHistorian;
$(document).ready(function() {
function unzoom() {
chartChartColumnRangeRate.options.chart.isZoomed = false;
chartChartColumnRangeRate.yAxis[0].setExtremes(null, null);
chartChartColumnRangeRate.yAxis[0].isDirty = true;
chartChartHistorian.options.chart.isZoomed = false;
chartChartHistorian.xAxis[0].setExtremes(null, null);
chartChartHistorian.xAxis[0].isDirty = true;
}
