Figure 6-7. Promoting a QLabel to a ClockWidget To be able to use this feature of Designer, you must provide a constructor taking a QWidget pointer and make the include file accessible for the make system. This can be done with the INCLUDEPATH variable in the QMake project file. It is important to pick a widget that is in your custom widget s inheritance tree to make sure that all properties shown in Designer are available for your widget. The user interface compiler generates code for setting all properties marked as bold in Designer. In the property box shown in Figure 6-8, the properties objectName, geometry, text, and flat will be set. This means that if you promote the widget, your widget needs to have the setObjectName, setGeometry, setText, and setFlat methods. If you choose to promote a widget from the inheritance tree of your custom widget, you get these methods free through inheritance. java qr code Java QR Code Generator - zxing example - JournalDev

16 Feb 2018 ... The ZXing (“zebra crossing”) is an open-source, multi-format 1D/2D barcode image processing library implemented in Java , with ports to other languages. In this section, we briefly cover some notation that we will use in this and in following chapters. We use m to denote plaintext, and c to denote ciphertext. We also use F and F 1 to refer to mathematical functions for encryption and decryption, respectively. We use k to denote the key. The encryption function F requires a plaintext message, m, and an encryption key as input, and produces a ciphertext message c as output. We denote the relationship between the encryption function, the plaintext, the ciphertext, and the key as F(m,k) = c. The decryption function F 1 requires a ciphertext message, c, and a decryption key as input, and produces a plaintext message as output. Similarly, F 1(c,k) = m. A symmetric cipher is an encryption and decryption function for which F 1(F(m,k),k) = m. If Alice wants to send m to Bob confidentially, she computes c = F(m,k), and then sends c to Bob. When Bob receives c, he computes m = F 1(c,k). The cipher is said to be symmetric because the same key is used for both encryption and decryption. qr code java app Generate QR Code Using Zxing Android Studio ... - Medium

At first glance, it might appear that a form framework would save you a lot of time, but in reality, form frameworks are rarely flexible enough to deal with all the situations you might want to develop, and in the long run you can sometimes find yourself spending more time creating custom fields for your form framework than it would have taken if you had coded all your forms manually. If you spend slightly more time implementing a plugin that works in Designer, you can skip the promotion method in Designer. Instead your widget will appear in the widget box with all the other widgets. Creating a widget plugin for Designer is pretty much a copy-and-paste job. Before you can start creating the plugin, you must make a small change to the widget class declaration. (For the plugin, you ll use the CircleBar widget developed earlier in this chapter.) The class declaration is shown in Listing 6-25. The first half of the change is the addition of the QDESIGNER_ WIDGET_EXPORT macro, which ensures that the class is available from the plugin on all platforms that Qt supports. The other half is the addition of a constructor taking a parent as argument. This is needed for the generated code from uic to work. qr code generator javascript example BeeTagg QR Reader for Java (en)
