I use EditString field as a TreeCtrl node for editing like in MS Word's list and for hiding it boundary i use edit.SetFrame(NullFrame()); But
all the same around EditString hidden indents exist. How to wrap border to text?

Not sure I understand the question, all seems OK to me. Can you provide example and/or commented screenshot?

Mirek, please check this example

class EditableTree : public TreeCtrl {
public:
	typedef EditableTree CLASSNAME;
	
	EditableTree() : selId_(0) {
		editNode_.SetCtrl(edit_);
		edit_.SetFrame(NullFrame());
		OpenDeep(0, true);
		
		WhenSel = THISBACK(OnSelect);		
	}
	
	void AddNode() {
		CloseEdit();
		
		selId_ = Add(0);
		Open(selId_);
		BeginEdit();
	}
	
	void BeginEdit() {
		editNode_.image = selNode_.image;
		SetNode(selId_, editNode_);
		
		String editval = "NODE" + AsString(selId_);
	   	edit_.SetData(editval);
   		edit_.Show();
    	edit_.AutoSize();
		edit_.SetFocus();//todo: at first not select because IsOpen is false*.
		edit_.SetSelection(editval.GetCount()); 
	}
	
	void CloseEdit() {
		if (selId_ > 0) {
			selNode_.value = ~edit_;
			SetNode(selId_, Node(~edit_));
			edit_.Hide();
		}
	}
	
	void OnSelect()
	{
		CloseEdit();
		selId_ = GetSel()[0];
		selNode_ = GetNode(selId_);
		BeginEdit();
	}
	
private:
	int selId_;
        EditString edit_;
   	Node selNode_;
   	Node editNode_;
};

GUI_APP_MAIN
{	
	TopWindow wnd;
	Button btn;
	wnd.Add(btn.SetLabel("Add").LeftPos(10).TopPos(10));
	
	EditableTree tree;
	wnd.Add(tree.VSizePos(40).HSizePos());

	btn <<= callback(&tree, &EditableTree::AddNode);
    wnd.Run();
}

In edit mode (when select) text shifts in horizontal

OK, that is because internal margin of EditField.

I have now added NoInternalMargin, which removes it. Use

edit_.NoInternalMargin().SetFrame(NullFrame());

http://i051.radikal.ru/1310/db/60428f3ba190.jpg

This code illustrate also a setting user defined font size, where some trouble occur with changing initial text's position

enum {fntSize = 19};

struct AppNodeSize : public Display {
	virtual void Paint(Draw& w,const Rect& r, const Value& q,Color ink,Color paper,dword style) const {
    	w.DrawRect(r, paper);
    	w.DrawText(r.left, r.top, (String)q, StdFont().Height(fntSize), ink);
  	}
  
  	Size GetStdSize(const Value& q) const { 
  		//1.5 is a empirical multiplier for increasing row height when fntSize used in (1) and (2);  		
  		//how to universally set it based on fntSize?
	 	return 1.5 * StdDisplay().GetStdSize(q);
	}
};
	
class EditableTree : public TreeCtrl {
public:
	typedef EditableTree CLASSNAME;
		
	EditableTree() : selId_(0) {
		NoRoot();

		editNode_.SetCtrl(edit_);
		edit_.NoInternalMargin().SetFrame(NullFrame());//crashes when NoInternalMargin
		edit_.SetFont(StdFont().Height(fntSize));//(1)
				
		WhenSel = THISBACK(OnSelect);		
	}
	
	void AddNode() {
		CloseEdit();
		
		//with some ico in /**/ offset lines more visible
		selNode_ = Node(/*espudImg::secExpand(), */"NODE" + AsString(GetChildCount(0) + 1));
		selNode_.SetDisplay(Single<AppNodeSize>());//(2)
                 
        selId_ = Add(0, selNode_);		
		BeginEdit();
	}
			
	void OnSelect() {
		CloseEdit();
		
		selId_ = GetSel()[0];
		selNode_ = GetNode(selId_);

		BeginEdit();
	}
	
private:
	int selId_;
   	Node selNode_;

    EditString edit_;
   	Node editNode_;
   	
	void BeginEdit() {
		editNode_.image = selNode_.image;
		SetNode(selId_, editNode_);

		String val = selNode_.value;	
   		edit_.SetData(val);
    	edit_.AutoSize();
		edit_.Show();
		edit_.SetFocus();
    	edit_.SetSelection(val.GetCount()); 
	}
	
	void CloseEdit() {
		if (selId_ > 0) {
			selNode_.value = ~edit_;
			SetNode(selId_, selNode_);
			edit_.Hide();
		}
	}   	
};

Another interesting task of setting the cursor when editing based on the current mouse position, i.e. like in Word's list. Additionaly with selection on hover. This may be a good example future.

NoInternalMargin fixed, the method definition you seek is

Size GetStdSize(const Value& q) const {
return GetTextSize((String)q, StdFont().Height(fntSize));
}

However, there are still some minor problems (selected node is vertically shifting); will fix those soon.

Mirek

P.S.: Complete testcase (for my reference):

#include <CtrlLib/CtrlLib.h>

using namespace Upp;

enum {fntSize = 19};

struct AppNodeSize : public Display {
	virtual void Paint(Draw& w,const Rect& r, const Value& q,Color ink,Color paper,dword style) const {
    	w.DrawRect(r, paper);
    	w.DrawText(r.left, r.top, (String)q, StdFont().Height(fntSize), ink);
  	}
  
  	Size GetStdSize(const Value& q) const { 
	 	return GetTextSize((String)q, StdFont().Height(fntSize));
	}
};
	
class EditableTree : public TreeCtrl {
public:
	typedef EditableTree CLASSNAME;
		
	EditableTree() : selId_(0) {
		NoRoot();

		editNode_.SetCtrl(edit_);
		edit_.NoInternalMargin().SetFrame(NullFrame());
		edit_.SetFont(StdFont().Height(fntSize));
				
		WhenSel = THISBACK(OnSelect);		
	}
	
	void AddNode() {
		CloseEdit();
		
		//with some ico in /**/ offset lines more visible
		selNode_ = Node(/*espudImg::secExpand(), */"NODE" + AsString(GetChildCount(0) + 1));
		selNode_.SetDisplay(Single<AppNodeSize>());//(2)
                 
        selId_ = Add(0, selNode_);		
		BeginEdit();
	}
			
	void OnSelect() {
		CloseEdit();
		
		selId_ = GetSel()[0];
		selNode_ = GetNode(selId_);

		BeginEdit();
	}
	
private:
	int selId_;
   	Node selNode_;

    EditString edit_;
   	Node editNode_;
   	
	void BeginEdit() {
		editNode_.image = selNode_.image;
		SetNode(selId_, editNode_);

		String val = selNode_.value;	
   		edit_.SetData(val);
    	edit_.AutoSize();
		edit_.Show();
		edit_.SetFocus();
    	edit_.SetSelection(val.GetCount()); 
	}
	
	void CloseEdit() {
		if (selId_ > 0) {
			selNode_.value = ~edit_;
			SetNode(selId_, selNode_);
			edit_.Hide();
		}
	}   	
};

GUI_APP_MAIN
{	
	TopWindow wnd;
	Button btn;
	wnd.Add(btn.SetLabel("Add").LeftPos(10).TopPos(10));
	
	EditableTree tree;
	wnd.Add(tree.VSizePos(40).HSizePos());

	btn <<= callback(&tree, &EditableTree::AddNode);
    wnd.Run();
}
