In this post, we’ll use the Free method or DelphiVCL.Application.Free to destroy an object and free its associated memory, if necessary. Learning how to do it will allow you to easily build GUIs with Python Development Tools.
Use Free to destroy an object. Free automatically calls the destructor if the object reference is not nil. Any object instantiated at run time that does not have…
In this post, we’ll use the Equals method or DelphiVCL.Application.Equals to check whether the current instance and the Obj parameter are equal. The function has one Obj parameter of the TObject type. Learning how to do it will allow you to easily build GUIs with…
In this post, we’ll use the EndFunctionInvoke method or DelphiVCL.Application.EndFunctionInvoke to block the caller until the specified ASyncResult completes. Learning how to do it will allow you to easily build GUIs with Python Build Tools.
Returns the result from…
In this post, we’ll use the EnumAllWindowsOnActivateHint property or DelphiVCL.Application.EnumAllWindowsOnActivateHint is a Boolean variable used for hint displaying. Learning how to do it will allow you to easily create GUIs with Python Programming Software.
EnumAllWindowsOnActivateHint is used internally by VCL for hint displaying. Do not use it directly.
Let’s browse all the…
In this post, we’ll use the EndInvoke property or DelphiVCL.Application.EndInvoke to block the caller until the specified ASyncResult completes. Learning how to do it will allow you to easily create GUIs with Python Windows GUI Builder.

In this post, we’ll use the DesignInfo property or DelphiVCL.Application.DesignInfo contains information used by the Form designer in Python Program Maker.
DesignInfo is used internally. Do not use this property in applications.
Let’s browse all the properties…
The ExeName property or DelphiVCL.Application.ExeName contains the file name of the application’s executable file including path information.
In this post, we’ll use Use ExeName to obtain the name of the executable file for the application. ExeName is the fully-qualified name, including the path to the application’s executable in Python Windows GUI Builder.

When the user invokes an action, a series of calls ensue to respond to that action. First, the action list that contains the action generates an OnExecute event. If the action list does not handle the OnExecute event, then the action is routed to the Application…
Align or TAlign is used to specify the alignment of control within its parent. TAlign specifies how control is placed relative to its parent.
It can have one of the following values:
Value
Meaning
alNone
The control remains where it was placed.
State property is used as an indicator for which items are selected or checked.
For example, for each member of the Items array, we use State to determine whether the checkbox is selected (cbChecked), cleared (cbUnchecked), or dimmed (cbGrayed).
Note: cbGrayed corresponds to the indeterminate state.
State combines the information provided by the Boolean Checked property and the…
