Hi,
can anyone help me on how to create a control array in C++ builder
like we create in VB.
Read the FAQ about arrays. You can use an array or a vector.
Example:
Control my_controls[50]; // an array of 50 Controls.
std::vector<Control> my_other_controls; // A vector of Controls.
If there is a parent class, then you can have an array of pointers
to controls, and put in pointers to child classes:
class Button_Control
: public Control
{
// ...
}; /* a Button_Control _is_a_ Control */
std::vector<Control *> my_control_ptrs; // Vector of Control ptrs.
Now if the Control class had a clear() method, you could do:
my_control_ptrs[0]->clear(); // Tell the first Control to clear.
or
for (unsigned int i = 0; i < my_controls_ptrs.size(); ++i)
{
my_control_ptrs
->clear();
}
for telling all the Controls to clear.
My brain is foggy at the moment, so I suggest you look at your C++
text book, compiler help manuals or the C++ FAQ for information
on declaring arrays of pointers.
I have another question regarding controls. I want to clear a group
of text boxes in the form on a button click. I am not using any
groupbox. how can i determine the control as Editbox and how can i
clear that.
Your other question is off-topic for this newsgroup. I have shown
how one method can be executed for a vector of objects. My intuition
says that the process is very similar.
any help would be appreciated.
thanx
