Maintain the widget position and size in C ++ Builder
C ++ Builder/Delphi is a popular Visual C ++/Pascal development tool developed by Inprise (formerly Borland), which greatly accelerates application development. However, because it is a visual programming tool, after you drag the control to the form, the control's position is fixed. As the size of the form or the screen resolution changes, the positions of the control and form are often very mess
1. Data to be displayed in the widget UI is stored in the provider as static variables.
I discussed with my colleagues the feasibility of the other two solutions:A. enable the Service to retrieve data. The data is stored in the service as static variables.B. stored locally.The quality of these three solutions lies in the fact that one thing is the lifecycle of static variables. In terms of Linux memory management, processes in the memory will not

The PyQt5 Main Window dynamically loads the Widget instance code, pyqt5widget
This article focuses on the sample code for dynamically loading widgets in the main PyQt5 window, as shown below.
We use Qt Designer to design two windows named MainForm and ChildrenForm ). We add a grid layout in the blank center of the Main Window and name it MaingridLayout. ChildrenForm needs to be put in.

Java. lang. ClassCastException: android. widget. FrameLayout $ LayoutParams cannot be cast to android. widget. LinearLayout $ LayoutParams

Recently, I was wondering how to compile an Android battery plug-in on the desktop. First, this App has practical value, and second, the compilation workload should not be very large, you don't have to spend too much time learning the development method of widgets, so you can do it three times. So you can pause the learning of Game Development and compile a Widget first.
After finding and combining multiple sources of data, we finally achieved the

I believe that when many bloggers develop C # winForm for the first time, when the form size changes, the controls in the form do not change with the changes in the form. Recently, due to a project, this problem also needs to be solved. Through Reading and learning, this problem has been solved. It may not be a good solution, but it is also worth learning...

The yiiYII widget creates a Login form. The YII Framework must follow the creation method of its form to create a logon model. the error is the same as that of the database operation model. The difference is that it does not interact with the database and uses widgets, before creating a form, the YII Framework must follow the creation method of its form.
