Is there a way to override the template of or restyle the carrot (and even completely remove as I need in one case)? The carrot being the position marker where the drop will occur. I'd also like the ability to change the icons used during dragging - I've seen an infinity symbol, an arrow, and a strike-through circle, for which all I'd like to use custom icons. Unfortunately, I'm also confused as to when a given icon displays itself.
Just reviewing the docs it would appear that the DragDropTarget has a GetInsertionIndicatorGeometry which I suspect is responsible for the various symbols shown when dragging.
Hence for you to replace these symbols you will need to inherit the specific target type you are using and override this protected member to inject your own geometries.

(Jacked straight from my last thread:) Reading through the GTK Book, there are lots of things to clean up when making sure to learn GTK3-focused skills. One is color selection widgets.
First, I'm wondering how GtkColorChooser is supposed to permit alpha choosing. The book just has you gtk_color_selection_set_has_opacity_control (GTK_COLOR_SELECTION (colorsel), TRUE);. There's a similar function for GtkColorChooser, but it doesn't seem to create anything. There's also the show-editor attribute that I flipped to TRUE without seeming to do anything.
Second, is there an equivalent notion to GtkColorSelectionDialog->colorsel for GtkColorChooserDialog? As in, can you access the GtkColorChooser widget from the parent dialog?
EDIT:
This is the source for the dialog creation where I'm missing something. I'm expecting this to show me an alpha-enabled color chooser widget, but it only gives me the regular swatches.
dialog = gtk_color_chooser_dialog_new(title, window);
gtk_color_chooser_dialog_set_use_alpha(GTK_COLOR_CHOOSER(dialog), TRUE);
My only guess is that I'm trying to access the color chooser incorrectly, but I haven't been able to find sufficiently detailed instructions about how to get to the chooser from the dialog.
the GtkColorChooser interface allows choosing the alpha channel by setting the :use-alpha property:
https://developer.gnome.org/gtk3/stable/GtkColorChooser.html#gtk-color-chooser-set-use-alpha
when the :use-alpha property is set, you can select the alpha when creating a new custom color in the editor; a new scale widget will appear at the bottom of the color editor and will let you select the alpha level:
the GtkColorChooserDialog is a GtkDialog with a GtkColorChooserWidget inside the dialog's content area, so you can use gtk_dialog_get_content_area() and then get the first child of the returned GtkBox. this is arguably a layering violation, and should not be needed: GtkColorChooserDialog proxies all the GtkColorChooser methods to its GtkColorChooserWidget, and you should never need to access the widget directly. if you want to keep control of the GtkColorChooserWidget, you should create your own GtkDialog and pack a GtkColorChooserWidget into it yourself. again, I would not recommend doing that unless you want to create your own custom dialog.
I am very new to Expression Blend but can't find any solution with google. I would like to style a Menu and it's items. But how can I see the actual look of the PART_Popup? The IsOpen Property is bound to something like {Binding IsSubmenuOpen, RelativeSource={RelativeSource TemplatedParent}}. It seems I am only looking at something complete invisible :). There is also a SystemDropShadowChrome but I actually can't see this thing. The eyes next to all the items are active. And even if I change some background colors all that I see is just a black transparent rectangle.
Is this a toolkit control (dropdownmenu) or a telerik (radmenu) or something? If you've already broken out the template (eg; Right click->Edit Template->Edit Current/Copy) Then there's a couple things you want to try to find it since sometimes they can be oddly embedded.
Go to the root level of the control, try Right Click->Edit Additional Templates->...
If that' doesn't provide your part_ look in your broken out template resource you've created and inspect your object tree. You're looking for embedded controls appearing as objects. Right click the embedded control in your object tree and edit its template (Current or Copy)
You'll potentially sometimes have to drill down multiple layers within a template to expose the objects you wish you to edit. If you specify which control you're working with I'm sure we can tell you exactly how to get to where you need more efficiently. Cheers!
Try exploring the States tab. Most likely some of the parts are only visible in certain states.
Is it possible to change the look of the data grid in silverlight (or any other object), by look i mean changing the depth or the effect of it so it looks 3d like and stands out?
Thanks,
Michelle
You can change the style of any object in Silverlight.
Search for Styles in Silverlight...
You can change the style for all controls of a certain type in your application or in a part of it. You can also change specific controls.
You can change the style conditionally (in function of the state, responding to a trigger etc.)

I'm working on a project that involves creating a custom graphical editor. The graphical editor has multiple tabs, and I want to create a preview function that will show a popup with Bitmap previews of the content of each of the tabs. However, the problem I'm running into is that the content for each of the tabs must be arranged before a proper preview can be generated for it. This means going into each of the tabs to ensure that they're rendered and arranged. Then, and only then, do the previews get properly generated, otherwise the previews have a size of 0x0. Does anybody know how to force an arrange of a content control so that I can get a properly sized preview generated ?
Apparently you can just call the 'Arrange' method directly, but you have to be careful about the rectangle you pass in as a parameter, because it can adversely affect the display of your control if you just want to force the object to draw itself (ie can force it to draw out of the desired position).
Here is a link to MSDN where it discusses the "arrangeOverride" method of a control.
I'm not sure this is what you need, but this method seems to be what you're asking about.
Hope this helps!
I'm pretty green when it comes to WPF, so forgive me if this is an obvious question.
I'm trying to modify an existing code base that is using the Divelements SandRibbon libraries, but am finding that the GalleryButton control doesn't behave quite how I'd like. What I'd like to do is change the way GalleryButton arranges the image and label, but keep the default 'look' for all triggers such as mouse over etc.
Is it possible to apply a ControlTemplate to some parts of a control but not others? I want to specify that the GalleryButton displays its 'Image' and 'Text' properties differently than the defaults, but not touch anything else.
Unfortunately no -- it's all or nothing. However, one solution I've used before is to simply sublass the control and alter the layout in code behind in OnApplyTemplate.
