Well, you're not used to "back and forth redesigns". )
There will probably be a new article next week. I will present the first version of the multiline input field. In subsequent articles, I'll gradually add everything discussed in private and on the forum.
I would add methods ItemsSelectedTotal(); ItemsUnselectedTotal(); along with ItemsTotal();
To CListView and CCheckBoxList?
I will, but not in the next article. So it will be quite a big article.

I will add it, but not in the next article. This is a rather large article.
Tol, how can I programmatically find out which checkbox of a list item is ticked. Without clicking on it.
I need to array all ticked items in the list.
I'm stumped. Please tell me in which direction to look.

CCheckBoxList::GetItemState()
Thanks. That's what I did. I was looping from 0 to ItemsTotal(). It was my fault, that's why it was glitching.
Can you tell me if the checkboxes' states are reset when switching timeframes?
If yes, what are the ways to bypass this unpleasant moment? (They are reset for me - maybe I'm doing something wrong).

You need to write to a file. And read it when installing GUI. This is the subject of a future article and there is still a long way to go.

Anatol, I'm trying to write Bid prices of characters written in table rows in column 0 to the table in the timer:
//| Timer|
//+------------------------------------------------------------------+
void CProgram::OnTimerEvent(void)
{
CWndEvents::OnTimerEvent();
//--- Pause between updating lists and tables
if(m_counter1.CheckTimeCounter()) {
uint sz=m_table_main_symbol_list.RowsTotal();
for(uint i=1; i<sz; i++) {
string sy=m_table_main_symbol_list.GetValue(0,i);
MqlTick tick;
if(sy!=NULL && sy!="") {
if(SymbolInfoTick(sy,tick)) {
int dg=(int)SymbolInfoInteger(sy,SYMBOL_DIGITS);
m_table_main_symbol_list.SetValue(1,i,DoubleToString(tick.bid,dg),dg);
m_table_main_symbol_list.TextColor(1,i,clrDimGray);
//m_table_main_symbol_list.UpdateTable();
}
}
}
//--- Redraw the graph
m_chart.Redraw();
}
//--- Pause between status bar updates
if(m_counter2.CheckTimeCounter()) {
//--- Redraw the graph
m_chart.Redraw();
}
}
//+------------------------------------------------------------------+
If done without UpdateTable(), no data appears in the table cells. If you update the table every time you get a new tick, it becomes impossible to work with the table - it blinks, the highlighted row blinks, etc....
How to get out of the situation?
