With the designer some times I experience problems that provocate the crash of the program. Then I've observed that removing some child from the graphic layout and inserting it directly in the class with Add(ctrl), and setting all its properties, the application works. The last case appeared with line edit just now. Please consider the following layout:

LAYOUT(VegaTab4Layout, 712, 496)
	ITEM(LabelBox, dv___0, SetLabel(t_("View")).LeftPosZ(32, 644).TopPosZ(376, 80))
	ITEM(Button, dv___1, LeftPosZ(484, 68).TopPosZ(424, 19))
	ITEM(Button, dv___2, LeftPosZ(48, 68).TopPosZ(424, 19))
	ITEM(Button, dv___3, LeftPosZ(156, 68).TopPosZ(424, 19))
	ITEM(Button, dv___4, LeftPosZ(272, 68).TopPosZ(424, 19))
	ITEM(Button, dv___5, LeftPosZ(380, 68).TopPosZ(424, 19))
	ITEM(Button, dv___6, LeftPosZ(588, 68).TopPosZ(424, 19))
	ITEM(Button, dv___7, LeftPosZ(484, 68).TopPosZ(396, 19))
	ITEM(Button, dv___8, LeftPosZ(48, 68).TopPosZ(396, 19))
	ITEM(Button, dv___9, LeftPosZ(156, 68).TopPosZ(396, 19))
	ITEM(Button, dv___10, LeftPosZ(272, 68).TopPosZ(396, 19))
	ITEM(Button, dv___11, LeftPosZ(380, 68).TopPosZ(396, 19))
	ITEM(Button, dv___12, LeftPosZ(588, 68).TopPosZ(396, 19))
	ITEM(LineEdit, lineedit, LeftPosZ(32, 644).TopPosZ(20, 348))
END_LAYOUT

with constructor:

VegaTab4::VegaTab4()
{
	CtrlLayout(*this);
	SizePos();
}

provocate the immediate crash of the application. To resolve the problem I need (all other being the same) to delete the line

ITEM(LineEdit, lineedit, LeftPosZ(32, 644).TopPosZ(20, 348))

and use the following constructor
[/code]
and the following constructor

VegaTab4::VegaTab4()
{
	CtrlLayout(*this);
	SizePos();
	Add(lineedit); // code of the previous deleted row
	lineedit.LeftPosZ(32, 644).TopPosZ(20, 348);
}

where I've declared "LineEdit lineedit;" in the class declaration.
Is it normal?
