In the past two days, I have summarized some problems encountered in the project. Some colleagues in other groups asked me how to define the front and back positions of various widget windows in QT. Here I will summarize: In QT, all the questions should be divided into two parts to discuss two different situations: one is the most common qwidget system, and the other is the qgraphicswidget system. ①: In the common qwidget system, the preceding and following positions are mainly set using

How to define the front and back positions of each widget window in QT In QT, all the questions should be divided into two parts to discuss two different situations: one is the most common qwidget system, and the other is the qgraphicswidget system. ①: In the common qwidget system, the preceding and following positions are mainly set using raise (), understack (), and hide () functions. In theory, every widget window in QT maintains its own creation stack (widget's stack .), the stack stores the

1. When writing widgets, we usually need to bind some events, preferably the binding events of these widgets plus the namespace of the current widget. If the same jquery object uses two widgets, and two widgets are bound to the same event name, there may be a problem. When destroying

Use DOJO to develop widgets for Business space Our custom widgets developed for this series are based on DOJO 1.2.3 and have been tested in V6.2 space Business on WebSphere integration Developer V6.2 using Mozilla Firefox 3.0.11 。 However, the common framework concept we developed also applies to DOJO applications that do not use Business space. Understanding this series requires a basic knowledge of the D

Now HTML5 more and more attention, but currently support HTML5 browser is not mainstream, especially domestic users nearly 50% still use IE6, because support HTML5 IE9 does not support the installation of XP system, so the future for a long time, HTML5 developers will have to consider backwards compatibility issues. There are many ways to HTML5 tag or CSS selector compatibility, in which a self-generated tag element is one.The basic principle is that the following code works in IE8, and the styl

called Client window. ITIS important to being aware of this if dealing with callback Functions:thereare 2 windows with 2 different callback Func tions. When creating child Windows,these child windows was typically created as children of the client Window;their parent is the Refor the client window.The Framewin window control actually contains 2 windows: the main window and the Subwindow, the child window called the client window, it is important to understand the concept of the main window and

objects without corresponding pointers, because we do not need to access them outside the constructor.To ensure that the exit button is always displayed in the lower-right corner of the dialog box, before adjusting the button itself, we first fill the horizontal layout with a scaling bar. By using the qobject: addwidget () and qobject: addlayout () methods, we add all the widgets and sub-layout to mainlayout or its sub-layout, this ensures that all

placed in the (0, 1) and (1, 0) areas respectively. (1, 1) No widgets are placed in the area. We use clutter to display images. To add a clutter to the gtk container, we need to add a clutterwidget to the location where the layout is needed, indicating that the clutter container will be used here, And clutterstage is required for any clutter. Therefore, we obtain an embed from the clutterwidget.Stage. The remaining operations are standard clutter ope

Due to changes in functions of the project, some items in the list need to be dimmed, that is, click events cannot be received. Because the custom style is designed in the list, I used the QListWidget and found this method after searching for the document: Ui-> listWidget-> item (row)-> setFlags (Qt: ItemFlag) 0); // row is the item row to be dimmed. The above method can only add data to or add QListWidgetItem for the QListWidget. When the custom widget is in it, it is found that this

Qt on Android: Enables full screen display of Qt Widgets and Qt Quick applications. androidwidgets There are many Android system versions. The newer version is 4.4, and the older version is 2.3. Android applications developed by Qt on Android are non-full screen by default on Android devices. Some applications require full screen display, such as games. So how can we achieve this?
