# Class Rebar



## Class for AutoHotkey Rebar custom controls



AHK version: 1.1.23.01



This class provides intuitive methods to work with Rebar controls created via **Gui, Add, Custom, ClassReBarWindow32**.



## Rebar Methods

* DeleteBand(Band)

* GetBand(Band [, ID, Text, Size, Image, Background, Style, Child])

* GetBandCount()

* GetBarHeight()

* GetLayout()

* GetRowCount()

* GetRowHeight(Band)

* IDToIndex(ID)

* InsertBand(hChild [, Position, Options, ID, Text, Size, Image, Background, MinHeight, MinWidth, IdealSize])

* MaximizeBand(Band [, IdealWidth])

* MinimizeBand(Band)

* ModifyBand(Band, Property, Value [, SetStyle])

* MoveBand(Band, Target)

* OnNotify(Param [, MenuXPos, MenuYPos, ID)

* SetBandStyle(Band, Value)

* SetBandWidth(Band, Width)

* SetImageList(ImageList)

* SetMaxRows([Rows])

* SetLayout(Layout)

* ShowBand(Band [, Show])

* ToggleStyle(Style)



## Useful Rebar Styles

Styles can be applied to Gui command options, e.g.: Gui, Add, Custom, ClassReBarWindow32 0x0800 0x0100



* RBS_BANDBORDERS   := 0x0400 - Add a separator border between bands in different rows.

* RBS_DBLCLKTOGGLE  := 0x8000 - Toggle maximize/minimize with double-click instead of single.

* RBS_FIXEDORDER    := 0x0800 - Always displays bands in the same order.

* RBS_VARHEIGHT     := 0x0200 - Allow bands to have different heights.

* CCS_NODIVIDER     := 0x0040 - Removes the separator line above the rebar.

* CCS_NOPARENTALIGN := 0x0008 - Allows positioning and moving rebars.

* CCS_NORESIZE      := 0x0004 - Allows resizing rebars.

* CCS_VERT          := 0x0080 - Creates a vertical rebar.

## Delete()

Deletes a band from a rebar control.



### Return

TRUE if successful, FALSE if there was a problem.



### Parameters

* **Band** - 1-based index of the band to be deleted.



## GetBand()

Retrieves information from a rebar band.



### Return

TRUE if successful, FALSE if there was a problem.



### Parameters

* **Band** - 1-based index of the band.

* **ID** - OutputVar to store the band's ID.

* **Text** - OutputVar to store the band's text.

* **Size** - OutputVar to store the band's size.

* **Image** - OutputVar to store the band's image index.

* **Background** - OutputVar to store a handle to the band's background bitmap.

* **Style** - OutputVar to store the band's style numeric value.

* **Child** - OutputVar to store a handle to the band's child control.



## GetBandCount()

Retrieves the count of bands currently in the rebar control.



### Return

The number of bands in the rebar control.



## GetBarHeight()

Retrieves the height of the rebar control.



### Return

The height of the rebar control in pixels.



## GetLayout()

Retrieves the current layout of bands in the rebar control.



### Return

A string containing information about the current bands. String format is: ID1,Size1,Style1|ID2,Size2,Style2|...



## GetRowCount()

Retrieves the number of rows of bands in a rebar control.



### Return

The number of rows in the rebar control.



## GetRowHeight()

Retrieves the number of rows of bands in a rebar control.



### Return

The height of the row from the corresponding band in pixels.



### Parameters

* **Band** - 1-based index of a band to retrieve the height from.



## IDToIndex()

Converts a band identifier to a band index in a rebar control.



### Return

The 1-based band index if successful, or 0 otherwise.



### Parameters

* **ID** - The application-defined identifier of the band in question.



## InsertBand()

Inserts a new band in a rebar control.



### Return

TRUE if successful, FALSE if there was a problem.



### Parameters

* **hChild** - Handle to the control contained in the band, if any.

* **Position** - 1-based index of the location where the band will be inserted. If you set this parameter to 0, the control will add the new band at the last location.

* **Options** - Enter zero or more words, separated by space or tab, from the following list to set the band's initial styles: Break, FixedBmp, FixedSize, Hidden, HideTitle, NoGripper, NoVert, TopAlign, VariableHeight. The following styles are applied by default** - ChildEdge, GripperAlways (can be disabled with NoGripper), UseChevron (only valid if IdealSize is set).

* **ID** - Integer value that the control uses to identify this band. This parameter is required to retrieve and set layouts.

* **Text** - The display text for the band.

* **Size** - Length of the band, in pixels.

* **Image** - 1-based index of any image that should be displayed in the band. SetImageList method must be called prior to this.

* **Background** - Path of a bitmap file that is used as the background for this band.

* **MinHeight** - Minimum height of the control, in pixels.

* **MinWidth** - Minimum width of the control, in pixels.

* **IdealSize** - Ideal width of the band, in pixels. If the band is maximized to the ideal width (see MaximizeBand method), the rebar control will attempt to make the band this width.



## MaximizeBand()

Resizes a band to either its ideal or largest size.



### Return

TRUE if successful, FALSE if there was a problem.



### Parameters

* **Band** - 1-based index of a band to be maximized.

* **IdealWidth** - If TRUE the ideal width of the band will be used to maximize



## MinimizeBand()

Resizes a band to its smallest size.



### Return

TRUE if successful, FALSE if there was a problem.



### Parameters

* **Band** - 1-based index of a band to be minimized.



## ModifyBand()

Sets band parameters such as Text and Size.



### Return

TRUE if successful, FALSE if there was a problem.



### Parameters

* **Band** - 1-based index of a band to be modified.

* **Property** - Enter one word from the following list to select the Property to be set** - Style, ID, Text, Size, Image, Background, MinWidth, MinHeight, IdealSize, Child (handle of control).

## OnNotify()

You can also call it from a function monitoring the WM_NOTIFY message, pass it lParam as the Param. Currently this method is used to retrieve the position for a menu when the Chevron button is pushed and prevent a number of rows higher then the one set by SetMaxRows method.

### Parameters

* **Band** - 1-based index of the band.

* **Width** - New width in pixels.

Sets a layout of bands in the rebar control.



### Return

TRUE if a valid layout was passed, or FALSE otherwise.



### Parameters

* **Layout** - A string containing information about the current bands. String format is** - ID1,Size1,Style1|ID2,Size2,Style2|...



## SetMaxRows()

Sets the maximum number of rows allowed in a rebar control. This method requires the OnNotify method to be implemented.
