Open and close additional window (QML)

由 旧城冷巷雨未停 提交于 2019-12-11 02:01:47
问题 Currently I have a window openning in the following way: property variant win Button { id: testButton MouseArea { onClicked: { var component = Qt.createComponent("test.qml"); win = component.createObject(testButton); win.show(); } } } Is it ok to create a window like this or there is a better way to do it (from QML, not from C++)? When I close this additional window (just by clicking "x" button), I want to connect it to another event (for example, changing color of the button). How to do it?

How to implement a master-details view Qt/QML on an Android tablet?

由 ♀尐吖头ヾ 提交于 2019-12-10 11:26:16
问题 I am porting an iOS app to Qt/QML targeting an Android tablet. I would like to keep the app's behavior similar to the original iOS version, which is based on a UISplitViewController . In other words, I need to build a master-details view using the tablet in landscape mode. In order to achieve this, I was thinking of using ListView backed by a ListModel as the master view so that whenever an item is selected in the ListView , a details view is dynamically displayed. At the moment I am

How to set currentIndex of SwipeView to currentIndex of TabBar “by reference” after going to specific page?

由 ╄→гoц情女王★ 提交于 2019-12-07 04:18:54
问题 I'm getting started with QtQuick Controls 2.0. I have experience with C++ and a small amount of experience with Qt, but I have not worked with QML before. I have a TabBar and a SwipeView that are linked to each other. What I mean by this is that when you select a page on the TabBar , the SwipeView goes to that page. When you swipe to a page from the SwipeView , the TabBar updates itself to reflect that. As a learning exercise, I decided to create a button that would send the user to the

System tray icon without widgets

问题 I'm wondering if there's a way to implement system tray icon + menu functionality without widgets module? 回答1: Qt 5.8 introduces a SystemTrayIcon QML type in the experimental Qt Labs Platform module, as part of the Qt Quick Controls 2 offering. It uses a native implementation directly from the Qt Platform Abstraction layer where available, and Qt Widgets as a fallback on other platforms. 来源： https://stackoverflow.com/questions/41095630/system-tray-icon-without-widgets
