Picture control

Picture controls can contain images in the following formats:

Bitmaps, with .BMP extensions

GIF or animated GIF files, with the .GIF extension

JPEG files, with .JPEG or .JPG extensions

PNG files, with .PNG extensions

You can create the image in another application or use a scanner to create it.

Picture format restrictions Unlike BMP and GIF images and ICO icons, JPEG and PNG images must reside in the file system, not in a PocketBuilder resource file (PKR) or in a database blob. You must deploy JPEG or PNG files to the current application directory or include the full path of the deployed image files that you want to use in a Pocket PC device or emulator. PNG files are not supported on the desktop, only on Pocket PC devices and emulators, and can only be added at runtime.

Properties

Picture property	Datatype	Description
Border	Boolean	Specifies whether the control has a border. Values are: TRUE – Control has a border FALSE – Control does not have a border
BorderStyle	BorderStyle (enumerated)	Specifies the style of the border of the control. Values are: StyleBox! StyleLowered! StyleRaised! StyleShadowBox!
BringToTop	Boolean	Specifies whether PocketBuilder moves the control to the top of the front-to-back order of the window. Values are: TRUE – Control moved to top FALSE – Control not moved to top
ClassDefinition	PowerObject	An object of type PowerObject containing information about the class definition of the object or control.
DragAuto	Boolean	Specifies whether PocketBuilder puts the control automatically into Drag mode. Values are: TRUE – When the control is clicked, the control is automatically in Drag mode. FALSE – When the control is clicked, the control is not automatically in Drag mode. You have to manually put the control into Drag mode by using the Drag function.
DragIcon	String	Specifies the name of the stock icon or the file containing the icon you want to display when the user drags the control (the ICO file). The default icon is a box the size of the control. When the user drags the control, the icon displays when the control is over an area in which the control can be dropped (a valid drop area). When the control is over an area that is not a valid drop area, the No-Drop icon displays.
Enabled	Boolean	Specifies whether the control is enabled (can be selected). Values are: TRUE – Control can be selected FALSE – Control cannot be selected
FocusRectangle	Boolean	Specifies whether a dotted rectangle (focus rectangle) frames the picture when it has focus. Values are: TRUE – Control will be framed when it has focus FALSE – Control will not be framed when it has focus
Height	Integer	Specifies the height of the control, in PowerBuilder units.
Invert	Boolean	Specifies whether the control displays with its colors inverted. Values are: TRUE – Colors are inverted FALSE – Colors are not inverted
Map3DColors	Boolean	Specifies whether the system 3D colors are mapped to the control. Values are: TRUE – Colors ar mapped FALSE – Colors are not mapped
OriginalSize	Boolean	Specifies whether the width and height properties of a bitmap image (picture) will be set to their original values. Values are: TRUE – Width and height set to original values FALSE – Existing width and height not changed In the Window painter, setting OriginalSize to TRUE overrides the existing width and height. You cannot change this property in a script.
PictureName	String	Specifies the name of the file that contains the picture.
Pointer	String	Specifies the name of the stock pointer or the file containing the pointer used for the control.
PowerTipText	Long	Specifies a PowerTip for the control
TabOrder	Integer	Specifies the tab value of the picture within the window (0 means the user cannot tab to the control).
Tag	String	Specifies the tag value assigned to the control.
Visible	Boolean	Specifies whether the control is visible. Values are: TRUE – Control is visible FALSE – Control is not visible
Width	Integer	Specifies the width of the control, in PowerBuilder units.
X	Integer	Specifies the X position (distance from the left edge of the window), in PowerBuilder units.
Y	Integer	Specifies the Y position (distance from the top of the window), in PowerBuilder units.
