Resizable Dialogs and Forms

Layout managers are responsible for automatic reposition of controls hosted in a window for which layout management is enabled. You can enable layout management for the following objects:

• dialogs
• dialog bars (panes)
• property sheets
• form views

A class, for which layout management is enabled, is called "host window". Its child controls are anchored to its edges. You can also specify a distance between controls and edges, and "move type", which defines how a child control is repositioned when its host is resized.

Dialog in initial state:

Dialog after resizing:

Sample code:

CMyDialog::CMyDialog()
{
	// Enable controls layout:
	EnableLayout();
}

BOOL CMyDialog::OnInitDialog() 
{
	CBCGPDialog::OnInitDialog();
	
	CBCGPStaticLayout* pLayout = 
		(CBCGPStaticLayout*)GetLayout();
	if (pLayout != NULL)
	{
		// Add controls to layout:
		pLayout->AddAnchor(
			IDOK, 
			CBCGPStaticLayout::e_MoveTypeBoth, 
			CBCGPStaticLayout::e_SizeTypeNone);
		pLayout->AddAnchor(
			IDCANCEL, 
			CBCGPStaticLayout::e_MoveTypeBoth, 
			CBCGPStaticLayout::e_SizeTypeNone);
		pLayout->AddAnchor(
			IDC_EDITBOX, 
			CBCGPStaticLayout::e_MoveTypeNone, 
			CBCGPStaticLayout::e_SizeTypeBoth);
	}
	
	return TRUE;
}
