Python is everywhere. It has proven its worth time and time again, whether the demand is for scalability, stability, processing, and I/O performance, or just for simplicity and readability to make maintenance and onboarding new staff easier. Its libraries are among the most well-documented and well-maintained code resources available, and its object-oriented, dynamically typed, interpreted…
John Elder of Codemy launched a Python Tkinter GUI tutorial series that aims to teach us all the basic information of cross platform development using the Tkinter framework in Python. Interestingly, part of this series is some advanced projects that help us discover Tkinter…
In the DelphiVCL Wiindows UI Toolkit TMonitorDefaultTo specifies which monitor to select when there is no match to the specified criteria.
TMonitorDefaultTo indicates which monitor should be used when the selection criteria do not match any of the monitors in the…
As a part of the DelphiVCL Windows UI Toolkit the DelphiVCL.Timer or TTimer is used to encapsulate the Windows API timer functions.
TTimer is used to simplify calling the Windows API timer functions SetTimer and KillTimer, and to simplify processing the WM_TIMER messages. Use one timer component for each timer in the application.
The execution of the timer occurs through its OnTimer event.
When performing development on Windows, the ComponentState property or DelphiVCL.Application.ComponentState is used to describe the current state of the component, indicating when a component needs to avoid certain actions.
ComponentState is a set of constants defined in…
When carrying out Windows development, use the CurrentHelpFile property or DelphiVCL.Application.CurrentHelpFile to indicate the current Help file.
You can read CurrentHelpFile to determine the name of the Help file that is currently used by the application when it…
The Action parameter in DelphiVCL is used to specify the action associated with the control when carrying out Windows development.
Action is the action object that is associated with the control. Actions allow an application to centralize the response to user commands. When control is associated with an action, the action determines the appropriate properties and events of the control (such as…
The ClassNameIs method or DelphiVCL.Application.ClassNameIs is used to determine whether an object is of a specific type when you develop windows software.
ClassNameIs determines whether an object instance or class reference has a class name that matches a specified…
Here’s another great talk from the recently concluded PyCon. In this video, Igor T. Ghisi will discuss data regression testing and how exactly this procedure can help you in your Python project. As the data structures of a project increase in size and complexity, it…
In the past few decades, computers have relied on interaction with the user via a graphical user interface, i.e., a GUI. It consists of a main window, a menu, a toolbar, buttons, labels, etc. There are various Python tools for building GUIs, and here I will go through seven of them. The general structure of these tools is similar – one has to define the main window, together with some components…
