Detailed Description

Control widget for images in an ImageView.

This control is used with an ImageView object. It displays a Gtk::TreeView showing the images in the ImageView and lets the user do things like deleting images and re-ordering them by drag and drop.

Member Function Documentation

addImage()

void goGUI::ImageControl::addImage

(

goAutoPtr< goSignal3DBase< void > >

img

)

Add the image given as goAutoPtr.

The image is just added to the ImageView, and is being deep copied. The goAutoPtr is currently not copied. The image is also automatically converted by ImageView to be displayable — this means the original data format is probably not retained in the copied version of the image.

Parameters

img	Image to add.

getImageChangedCaller()

goCaller1< void, goAutoPtr< goSignal3DBase< void > > > & goGUI::ImageControl::getImageChangedCaller

(

)

This goCaller is called whenever the current image changes.

The parameter of the caller is a pointer to the current image.

Returns

The respective goCaller.

imageViewChanged()

void goGUI::ImageControl::imageViewChanged

(

int

code

)

Slot that gets called whenever the image view changes.

If the current image has changed, the caller returned by getImageChangedCaller() gets called with the new current image as argument. In the other cases, the treeview showing the images gets rebuilt.

Parameters

code	One of ImageView::CURRENT_IMAGE_CHANGED, ImageView::IMAGE_SET, ImageView::IMAGE_REMOVED.

setImageView()

void goGUI::ImageControl::setImageView

(

ImageView *

iv

)

Set the ImageView object.

Parameters

iv	The ImageView object to be used with this ImageControl.
