TclButton

A TclButton is a general-purpose push button for use in applications. When the button is clicked, we can navigate to a function, procedure or activate other actions.

AddNewButton (TComponent, xName, xCaption): TClButton

TComponent : The variable name of the defined component is written. Here you should write the component variable name of whatever your component will be in.

xName : The name of the defined button should be written.

xCaption : You can add a title.

Let's create a button.

1. Create a new project.

2. You need to define TclButton on the form. To do this, you should add under the var parameter on the ide as follows. It is the name of your variable you typed at the beginning. You should define this as you want and add it as TclButton.

var
testButton : TclButton; 

3. Add the TclButton to the form. For this, you must add the begin end block and add it inside the form after the form is defined. By saying MyForm.AddNewButton, we actually add to the form we have defined. Here, you need to add your form definition as whatever you wrote it.

testButton:= MyForm.AddNewButton(MyForm,'testButton','Test Button Caption');

4. If you do not want to define it in the form, you can add it in another component (such as Layout, Panel). Of course, before that, that component must be defined.

testLayout := MyForm.AddNewLayout(MyForm,'testLayout');
testButton:= MyForm.AddNewButton(testLayout,'testButton','Test Button Caption');

5. While defining the component, you can define it manually by typing. Another method is to write its shortcut. If you type "AddNewButton" while the shortcut is in the code block, a pop-up menu will appear.

As soon as you click, the following block will come automatically.

AddNewButton(xOwner:TComponent; xName,xCaption:String);

6. We gave the variable name while defining the TclButton in var. Now when you add this in begin end you should use this variable name in all definitions. Your code will throw an error when you write these variable names incorrectly.

7. You give a title to your Button component as the last parameter when defining your project. This title is the text that will appear on the screen when the application is run. You may not want to write this title while defining it.

testButton:= MyForm.AddNewButton(MyForm,'testButton','');

8. Then you can make a definition as follows. Well, an external title can be entered so that it does not appear empty when this project is run. For this, a title can be added with label.Caption assignment.

testButton.Caption := 'Button Caption';

9. Another use of Button is to add text. If we add text to our component by saying button.text, when the project is run, the title does not appear and the value you have written in the text starts to appear.

testButton.Text := 'Button's Text';

For example, take the value written in an TClButton component and put it in the button and show me this. Below we show you how to do this.

testButton.Text := testEdit.Text;
ShowMessage(testButton.Text);

10. Now let's design our TclButton component. Let's set the width and height first. For this, you must make the following definitions.

testButton.Height := 50;
testButton.Width := 150;

11. With the Align parameter, you can specify where you want our component to be aligned in the form. This parameter has multiple positioning properties. See the page to learn about these features. We're going to call it the top part here. So we have to write "AlTop".

testButton.Align := alTop;

12. With the Margins parameter, you can give margins at any scale from the right, left, bottom, top.

testButton.Margins.Left:= 50;
testButton.Margins.Right:= 10; 
testButton.Margins.Top:= 50;
testButton.Margins.Bottom:= 10;

13. You may want to change the appearance of the text in the tag. We will use the TextSettings parameter for this.In order to use this parameter, you have to make the following definition. Otherwise your commands will not work.

testButton.StyledSettings := ssFamily;

To adjust the text size;

testButton.TextSettings.Font.Size := 20;

To set the text color;

testButton.TextSettings.FontColor := clAlphaColor.clHexToColor('#8a067c');

14. To tell you the truth, you have created a simple application that does nothing yet. Let's save and start using our project. You can save in one of two ways:
Click the save icon (the button in the upper right corner) or press Ctrl + S to save the project and see what you've done on the platforms now.

Example:

Base Syntax

 var
   MyForm:TclForm;
   testButton : TclButton;
 
 begin
   MyForm := TclForm.Create(Self);
   testButton:= MyForm.AddNewButton(MyForm,'testButton','Click');
   testButton.TextSettings.Font.Size:=50;
   testButton.Align := alCenter;
   testButton.Height := 50;
   testButton.Width := 100;
   
   MyForm.AddNewEvent(testButton,tbeOnClick,'ShowMessage(Hello);');
   
   MyForm.Run;
 
 end;

TRObject Syntax

 var
   MyForm:TclForm;
   testButton : TclButton;
 
 {
   MyForm = TclForm.Create(Self);
   testButton= MyForm.AddNewButton(MyForm,'testButton','Click');
   testButton.TextSettings.Font.Size=50;
   testButton.Align = alCenter;
   testButton.Height = 50;
   testButton.Width = 100;
   
   MyForm.AddNewEvent(testButton,tbeOnClick,'ShowMessage(Hello);');
   
   MyForm.Run;
 
 }

Output:
