Look at yourself when create timgage control problem

CodePudding user response:

When creating a TIMage, given name attribute to the image, add a tag

 
SetLength (image, 4); 
. 
Image: [I]=TImage. Create (Self); 
Image [I]. Caption:='open'; 
Image [I]. Name:='Name' + inttostr (I); 
Tag image [I]=I; 
Top image [I]=Top; 
Left image [I]=Left; 
Image [I] : OnClick=ClickImage; 
.

In the event of an image ClickImage click

 
If the sender is TImage then 
The begin 
I:=(sender as TImage). The tag; 
Showmessage (image [I] name); 
end;

CodePudding user response:

Controls the name just in writing the code used to obtain control object, and dynamically created controls have direct access to the object, the name has no meaning,

CodePudding user response:

Upstairs said identity I normally use the built dynamic array to record the dynamic object, 9/f, the classmates have given unless you want to use the name of course is solution of 6th floor
