checkbox in C++ Builder

[Eugen_E]

How I can generate an "array" of checkboxes in C++ Builder?
The size of the array is determined at runtime, like this:

columns
Ξ Ξ Ξ
Ξ Ξ Ξ
Ξ Ξ Ξ
Ξ Ξ Ξ rows Ξ - checkbox

The tutorials I read only show how to put the checkboxes at design time, using the editor and object inspector. I don't know many things about object programming and C++ Builder, but I need to do a very, very simple project.
Thanks for your help.

Probably you can obtain Xmin, XMax, YMin and YMax coordinates for your area.
For example you have to create three (N=3) rows of checkboxes. Then you should to calculate

x_step = (XMax - XMin)/N;
First column will start from x = XMin the second - from XMin + x_step, and the third - from XMin + 2*x_step (this is equal to XMax)
Do the same about Y coordinates.

And then just run loops.
for(y = YMax; y >= YMin; y-=y_step)
for(x = XMin; x <= XMax; x+= x_step)
{
// Here you create checkbox and move if to x, y
}

Looks like it's the best solution for you.

Sorry,
actually I don't know how to create a checkbox in code. I only know to put the checkbox on the form with the mouse , from the controls available.

Problem solved, a checkbox can be created in code, with something like this:

TCheckBox* MyCheckBox[max_lines][max_cols];

for(y = YMax,i=0; y >= YMin; y-=y_step,i++)
for(x = XMin,j=0; x <= XMax; x+= x_step,j++)
{
MyCheckBox[j]=new TCheckBox(this);
MyCheckBox->Parent=Form1;
MyCheckBox->Left=x;
MyCheckBox->Top=y;
}
