**Init( **[//strategy//] [,//minimum size//] [,//maximum size//] **)**

{{blk2blue.jpg|blk2blue.jpg}}

| **Init** | Initializes the WindowResizeClass object. |
| //strategy// | An integer constant, variable, EQUATE, or expression indicating the overall strategy for resizing and repositioning all the controls on the window. If omitted, //strategy //defaults to **AppStrategy:Resize**, which rescales all controls in proportion to the parent. |
| //minimum size// | An integer constant, variable, EQUATE, or expression indicating the minimum size of the window. A value of one (1) sets the minimum window size to its design size. If omitted, //minimum size //defaults to zero (0), which indicates no minimum. |
| //maximum size// | An integer constant, variable, EQUATE, or expression indicating the minimum size of the window. A value of one (1) sets the maximum window size to its design size. If omitted, //maximum size //defaults to zero (0), which indicates no maximum. |

The **Init **method initializes the WindowResizeClass object and sets the overall strategy for resizing and repositioning window controls. You can use the SetStrategy method to override the overall strategy for individual controls.

**Implementation:**

The Init method adds the IMM attribute to the WINDOW.

If the //strategy //parameter is present, Init applies a strategy to each control based on the parameter value. If the //strategy //parameter is absent, Init applies the default strategy to each control. The default //strategy //is to rescale all control coordinates (x, y, width, and height) proportionally with the parent.

The parent may be the WINDOW containing the control, or it may be another control on the WINDOW. The SetParentControl and SetParentDefaults methods determine the parent for a given control.

The //strategy //parameter EQUATEs are declared in RESIZE.EQU as follows:

**  ITEMIZE(0),PRE(AppStrategy)**

**Resize         EQUATE  !Rescale all proportionally**

**Spread         EQUATE  !Resize surface controls, move others**

**Surface        EQUATE  !Max surface controls, move others**

**NoResize       EQUATE  !Does not resize any controls**

**Centered       EQUATE  !Reposition and center controls**

**  END**

The purpose and effect of these strategies are:

| Resize | Scales all window coordinates by the same amount as the parent, thus preserving the relative sizes and positions of all controls. This is the default strategy. |
| Surface | Makes the most of the available pixels by positioning other controls to maximize the size of LIST, SHEET, PANEL, and IMAGE controls. |
| Spread | Preserves the design-time look and feel of the window by applying the following strategies by control type: |
| Centered | Does not resize the controls, but repositions them relative to the window resize. |
| BUTTON | Horizontal and Vertical position (X and Y coordinates) are "fixed" relative to the nearest parent border; width and height are unchanged. |
| RADIO | Horizontal and vertical position are scaled with the parent, but width and height are unchanged. |
| CHECK | Horizontal and vertical position are scaled with the parent, but width and height are unchanged. |
| ENTRY | Width, horizontal and vertical position are scaled with the parent, but height is unchanged. |
| COMBO+DROP | Width, horizontal and vertical position are scaled with the parent, but height is unchanged. |
| LIST+DROP | Width, horizontal and vertical position are scaled with the parent, but height is unchanged. |
| SPIN | Width, horizontal and vertical position are scaled with the parent, but height is unchanged. |
| Other | All coordinates are scaled with the parent. |

**Even though LIST and COMBO controls may be resized, the column widths within them are not resized. However, the right-most column does expand or contract depending on the available space.**

**Example:**

** OPEN(window)**

** Resizer.Init(AppStrategy:Surface)      !initialize Resizer object**

** ACCEPT**

**  CASE EVENT()**

**  OF EVENT:CloseWindow                  ! on close window,**

**   Resizer.Kill                         ! shut down Resizer object**

**  OF EVENT:Sized                        ! on sized window,**

**   Resizer.Resize                       ! resize & reposition controls**

**  END**

** END**
