Function Documentation

anchor_control()

BOOL anchor_control	(	HWND	dialog,
		DWORD	control_id,
		WORD	anchor_topleft,
		WORD	anchor_bottomright )

Anchor an individual control to specific edges of the dialog, overriding any previous anchor.

Registers or overrides the anchor points for the specified control in the layout engine. This function can be used after attach_layout() to override anchors loaded from a resource, or after init_layout() to add anchors manually.

Parameters

dialog	Handle to the dialog box (HWND).
control_id	Control ID (e.g., IDC_BUTTON_OK).
anchor_topleft	Anchor flags for the control's top-left corner (see Anchor flags).
anchor_bottomright	Anchor flags for the control's bottom-right corner (see Anchor flags).

Returns

TRUE if the anchor was set successfully, FALSE on error (e.g., illegal anchor or control not found).

Note

It is safe to use anchor_control() after attach_layout() to override anchors set by the resource, or to add anchors for additional controls at runtime.

Example usage:

attach_layout(hInstance, hDlg, MAKEINTRESOURCE(ID_MAINDIALOG_LAYOUT));
anchor_control(hDlg, IDC_MY_BUTTON, ANCOR_RIGHT | ANCOR_BOTTOM, ANCOR_RIGHT | ANCOR_BOTTOM); // override/add anchor

attach_layout()

void attach_layout	(	HANDLE	resource,
		HWND	dialog,
		LPCTSTR	layout_resource_name )

Attach a dynamic layout to a dialog box using a layout resource.

Loads the layout information from the specified resource and applies it to the dialog, so its controls will resize and move according to the layout rules when the dialog is resized.

Parameters

resource	Handle to the module containing the resource.
dialog	Handle to the dialog box (HWND).
layout_resource_name	Name of the layout resource (e.g., MAKEINTRESOURCE(ID_MAINDIALOG_LAYOUT)).

Note

Call this function in WM_INITDIALOG after creating the dialog.

Example usage:

attach_layout(hInstance, hDlg, MAKEINTRESOURCE(ID_MAINDIALOG_LAYOUT));

init_layout()

void init_layout

(

HWND

dialog

)

Initialize dynamic layout management for a dialog.

Prepares the dialog for dynamic layout by creating an internal layout structure. Controls can then be anchored individually using anchor_control().

Parameters

dialog

Handle to the dialog box (HWND).

Note

Call this function in WM_INITDIALOG if you are not using a layout resource table, and plan to manually anchor controls using anchor_control().

Example usage:

init_layout(hDlg);
anchor_control(hDlg, IDC_BUTTON_OK, ANCOR_RIGHT | ANCOR_BOTTOM, ANCOR_RIGHT | ANCOR_BOTTOM);
