Flags
Options
Values
ESO_AUTORESIZE This option tells EasySize to simply send a WM_SIZE message without any data about position or dimension. Use this option
for windows that automatically size themselves (rebars and status bars)
ESO_INVALIDATE This option tells EasySize to invalidate the window after sizing it.
Remarks
None.
Anchor flags
This are the values you should use as left, top, right and bottom anchors to anchor a window.
Values
ESF_BORDER This flag tells EasySize to keep the distance from the border this flag is used on.
ESF_KEEPSIZE This flag tells EasySize to maintain the size of the window instead of anchoring it to the border, that is, it expands the space
between the window and the border. This flag shouldn't be set to facing borders: e.g. it shouldn't be set on both top and bottom, or on both left and right.
Remarks
None.
C++ (EasySize class' functions)

Parameters
hwndParent [IN] Handle to the parent window of the dialog control.
id [IN] ID of a dialog control.
left [IN] Left anchor.
top [IN] Top anchor.
right [IN] Right anchor.

EasySize::Empty() Removes all the windows being anchored.
Prototype
void EasySize::Empty();
Parameters
None

None
Remarks
It is not necessary to call this function when the class object is destroyed.
EasySize::SizeContents() The function that does the job of resizing the window that have an anchor.
Prototype
void EasySize::SizeContents();
Parameters
None
Return values
None
Remarks
This function should be called only in response to a WM_SIZE message, it's useless elsewhere.
EasySize::RedoComputations() This function recalcs all the windows distance from the border.
Prototype
void EasySize::RedoComputations();
Parameters
None
Return values
None
Remarks
This is an helper function that should be called only when you call SetWindowPos on your own on a anchored window.
C
EasySize_DoComputations
Prototype
void EasySize_DoComputations(ANCHORPOINTS *ap);
Parameters
ap [IN] Pointer to an ANCHORPOINTS structure, whose hwndToResize must be valid.
Remarks
This function is called internally when adding a window anchor, so you don't need to call it manually. It's an helper function that
should be called only when you call SetWindowPos on your own on a anchored window.
EasySize_SizeContents The function that does the job of resizing the window that have an anchor.
Prototype
void EasySize_SizeContents(const ANCHORPOINTSSTRUCT *aps);
Parameters
aps [IN] Pointer to the ANCHORPOINTSSTRUCT structure that contains the array of ANCHORPOINTS structures with all the window anchored.
Return values
No return values.
Remarks
This function should be called only in response to a WM_SIZE message, it's useless elsewhere.
