I would like to know a way to change the view of a particular pane in a splitter window.
It should be something like an explorer window. Where on click of any tree branch on left side of window right hand side view updates.
Similarily i would like to update my view. On click of any tree node a new pane should be displayed at the same position overriding the previous pane.
sample code would be highly appreciated
Do you really need to replace view or just change what view displays?
By replacing view I mean use different window; for example: replaced CEdit derived view with CFormView derived.
Could you please explain in greater detail what you are trying to accomplish?

I'm currently working on a project that utilizes an MDI Form. What I would like to achieve is that when the user hovers over one of the menu options in the MDI menu, a ToolTipText appears describing what can be found in said menu. I'm aware of the fact that in some options for VisualBasic 6, ToolTip is supported. However, I can't seem to add this to the MDI Form, or add a label control for that matter. Has anyone ever run into this problem, and if so, is there a workaround or a solution?
Please let me know if you have any additional questions or comments. Thank you in advance.
I'm not aware that any true menus on a VB6 for (even non-MDI) have a tool-tip property; hence, neither does the MDIForm when one its child forms has its menu displayed.
However, there are a few controls that can be put on the MDI parent form. The most useful of these is probably the PictureBox, into which you can then place any type of control, such as CommandButtons. It must be "docked" to either the top or bottom of the MDIForm, using the PictureBox.Align property. Controls within the PictureBox can be located any way you wish, and can have their normal ToolTip properties set.
Another MIDForm-usable control that I've had good luck with is the ToolBar control, which comes in as part of the CommonControls component. Like the PictureBox, it has a .Align property to set it to the top or bottom of the MDIForm. You can put any reasonable number of "buttons" on it, and have reasonable control over their appearance (graphics, etc.); apropos the OP's query, you can assign a ToolTip to each button. It wouldn't be difficult to have the buttons change depending upon the currently-active form, just as the MDI menus normally do.
One other alternative that can be considered (but may be quite tedious to implement) could be reading the Mouse.X and Mouse.Y properties for each MDI menu and setting the captions of a Label control (or TextBox) using the Mouse Hover event.
You'd need to find the top left and bottom right points for each MDI menu and if it is within the box, you can show your label control with the intended caption. But note that you can't just put any controls on an MDI Form except maybe PictureBoxes, Toolbars and Coolbars, etc.
So the Label or TextBox control would have to be first placed on top of a PictureBox control which can be top aligned.
I have a lot of view controllers in my Storyboard which makes navigation a bit difficult. When I click on a view controller or other item in the document outline, it will scroll automatically to the graphical representation of this view controller. However, when clicking on the graphical representation the document outline list does not automatically scroll to the selected item. I have to scroll through this list until I see something selected to know it is the correct one.
Is there a way to select a view controller in the graphical view, and let the document outline scroll to this view controller?
Another related annoyance is that if you filter the document outline to find the correct view controller, and click on that view controller, it will be scrolled away when you reset the filter again. Is there any way to prevent that from happening?

When clicking on an object (view controller, view, etc.) in a storyboard scene in the graphical editor in Xcode, Xcode 6 does scroll the hierarchical view so that the selected object is at least partially visible. Also, hierarchical list for that scene opens up so that you can see the object. So in the 2 years since you asked this question, at least that much has improved.
Another improvement: if you point to a view controller at the top of a storyboard scene in the graphical editor, a small view pops up with the name of the scene, which makes finding it in the list a little bit easier.

This also seems to have improved: the selected view controller remains visible even after clearing the search field.
How can I change the z-value, or just send to back or to front the objects in Interface Builder?
i.e. I would like to move to front the "Label" in this View:
You need to reorder then in Interface Builder. It seems like you're using Xcode 4. So, first, click on the arrow in the bottom left corner of IB to expand the side panel:
Next, click and drag the views that you'd like to rearrange.
The lower an item is on the list from the top of the list, the higher its "z-index".
with that object selected, goto (menu) Editor>Arrangement> . There will be 4 options with activated appropriate options.
xCode 10.3 (2019):
I had the same problem when copying/pasting a background image view. I couldn't drag it to change its z-order in the Document Outline panel (in Interface Builder).
The answer was just to restart xCode.
I think that re-indexed/re-built the storyboard and I could drag it higher in the list (thus making it lower in the z-order + behind the other controls).
I want to use the same sort of UI style of Xcode has right above the editor pane, as show below:
I've browsed through all the Views in Interface Builder and can't figure out what type of view this is. At this point I'm merely referring to the bar itself; not to the controls nested inside the bar, though I will be adding dropdowns in the same way as this.
What type of view should I be looking for?
TextMate uses one along the bottom of the editor too, which provides similar controls:
see:
$(DEVELOPER_ROOT)/Applications/Utilities/Accessibility Tools/Accessibility Inspector.app
just open Accessibility Inspector.app and move the cursor over the views you're interested in for details (you may need to enable accessibility options in system preferences.app).
it's also helpful to press cmd+F7 to lock onto a view and then to inspect its children.
so... 3 primary options:
1) if you want drag & drop convenience, you can simulate it with a Gradient Button
2) or you can use the button with a custom image in the button to achieve something closer
3) or just create a new view subclass and render it using a CGGradient or NSGradient
Let's say I have a split view, and I want to fill half of it with a table view (a fairly common use case, I would think). Is there any way to tell the table view to size itself to fit the split view or do I really have to size it manually?
I've done this, the way Jon Hess mentions first. Assuming you're using Interface Builder version 3:
Drag and resize your GUI (tableview from what I understand?) component to fit into the enclosing area the way you want it.
Click it to select it.
Press Command-Shift-I to open the inspector window for this GUI component. The inspector window should now actually show that you've selected a "Scroll View".
Click the "ruler" heading to be able to set the sizing. You'll see to the right an animated representation of how your GUI component will behave within its enclosing GUI component, and to the left another represenation of the same, without animation, but with four springs and two struts that you can turn on or off.
Turn all six things on, making them red.
Voilà :-)
It's generally easier to create the subviews first, then use the Layout/Embed Objects In/Split View menu item to create the split view around them.
As far as I know, doing it manually is the only way to go. However, if you turn on "snap to cocoa guidelines", the inner view will snap to the edges of the enclosing view as you drag towards them. This makes it easier than having to manually mouse the edges into place, or manually edit the sizes to match.
You can set all of the springs and struts of the table view to "on" in the size inspector and that will cause the table view to fill the split view. Alternatively, you can use the outline view in the main document window to place the tableview's enclosing scroll view directly into the splitview instead of in an intermediary custom view.
