Ctrl_Resize

The "Ctrl_Resize()" function is called when your interface has been re-sized. The user can not directly manipulate the size of the interface window, so this is not a common occurrence. Resizing happens once when the interface window is created, and whenever the user changes the size of the interface tools.

All the interface tools are "mapped out" in this function.

Syntax

extern "C" __declspec(dllexport) int Ctrl_Resize(

HWND wnd,

int width,

int height

)

Parameters

wnd

A handle to the interface's window

width

The horizontal size of the window (in pixels).

height

The vertical size of the window (in pixels).

Return value

The function returns "0" if an error occurred, "1" otherwise.

Remarks

Requirements

Header:

sliceO_include.hpp

Library:

sliceO_Structures.lib

Example

Sample Resize function from the "Edit mode" module.
