I add an item to the CMFCPropertyGridCtrl, but the new item does not show up only if i click the CMFCPropertyGridCtrl.
Now i have a indirect solution to show up the new item by calling ExpandAll(), but i don't want to expand those i have collapsed.
Is there a way to show up the new item gracefully ?
After CMFCPropertyGridProperty.AddSubItem() call, new item will show up by the following two calls:
YourGridCtrl.AdjustLayout();
YourGridCtrl.RedrawWindow();
Hope it helps !

So i created an expandable listView, works just fine. The problem is when i try to click an item witch has no children occours an exception because the function getChildrenCount is null. How can i solve this guys ? I really wanted this single item to have no children.
So actually the solver to this was really simple. I just had to use a setOnGroupListener on this case cause i wanted to show a new intent right after i click on the Group item, instead on the other items that i used setOnChildListener cause i wanted to expand the group to a few childs and then on the childs i wanted to do something.
I am new to TestComplete. I have a question and it may be something impossible or too simple. I have a toolbar containg File, Edit, View, etc. I want to get one item (eg. Edit) to mapped objects. I can get the whole toolbar only. I want to simulate a click event on Edit. How can I do this?
As a rule, TestComplete does not work with menu items as with separate objects. It works with a menu object or even only with a menu's parent object and you can specify which item to select by passing the caption of this item to the corresponding method of a menu object. For example:
objMenu.Click("Edit|Paste");
// or
parent.MainMenu("Edit|Paste");
Please find more details on how TestComplete interacts with menus in the Working With Menus help topic.
I am developing the following screen
The fourboxes next to each other are buttons. On clicking of the buttons I am changing the adapter of the listview.
Since the content above the listview took up lot of space I made the whole thing as an header and added it via code.
myPollsList = (ListView) findViewById(R.id.listArea);
myPollsList.addHeaderView(getLayoutInflater().inflate(R.layout.profile_listview_header, null));
Now I want to show some view when the list is empty. But if I do that then the header also goes away.
I am using this in a Activity and not a ListActivity. Any suggestions or workarounds for showing the header even when the list is empty ?
EDIT: Refer to my earlier question here ListView not getting space to show content on smaller screens . This is where someone suggested me to solve the problem by putting it as a header
I found a simple solution for this problem. If there's no elements for list and you are not adding the adapter, just add this:
mListView.setAdapter(null);
and the header will appear. It's easier than adding empty / fake item to the list.
So this is how I solved it. I had a custom adapter which was connected to the listview. When it found that it had zero items to display. It would add a fake empty view as an item to the list.
maybe you will like this Android addHeaderView disappears when no items in ListView
override/subclass your adapter to return false from isEmpty()
Don't use top layouts of button as header for list view.
So to adjust UI without using list header use weights.
Give parent Linear layout weight sum as 4 and 1, 1 to top Layouts and 2 for list view.
I'm working with the rich:pickList and it's working fine. I just need to find a way to disable the remove button at the moment I select an item located in the target list.
I suppose it could be done with JavaScript or JQuery but I have no experience with that.
The most I've done is to get the text of the selected item of the target list, but I would like to obtain the entire object represented by that item. Besides, I have looked for the button in the DOM tree but the button has no id, so I can't figure out how to find the button in order to can give it the right style class to disable it, and how to do this!
Try setting the attribute of rich:pickList removeVisible. This will display/undisplayed the remove button in the component.
Hope this helps.

First I apologize for the length but I want to ensure I get enough information out. I have an interesting problem that really shouldn't be difficult. I know that if you want to have the NSOutlineView scroll to and want display a specific row you simply use this pattern:
NSInteger row = [self.myOutlineView rowForItem:myItem];
[self.myOutlineView scrollRowToVisible:row];
I am not using a NSTreeController in favor of using delegation.
I am using an adapter pattern class to act as my data. The adapter wraps a number of different types. It is a simple structure:
[adapter children] ----- *[adapter parent]
So the adapter takes care of dealing with child count, can add, can remove, can expand, etc. and also acts like a data transport object.
So with that all out of the way here is the crux of the problem. When I add a new item to the NSOutlineView I start by adding a new child adapter to the adapter that is selected in the outline view. Then I reload the item with the children using:
[self.myOutlineView reloadItem:selectedAdapter reloadChildren:YES];
I then display the view for this object and attempt to synchronize the NSOutlineView so the selected row relates to the newly displayed view. So in a simple way the steps are:
Initially load the NSOutlineView with data utilizing the NSOutlineDataSource protocol
User selects an item (adapter) that can add child items
User clicks "Add" button
A new empty represented object is created
The new represented object is wrapped in an adapter
The newly created adapter is added to the children of the selected adapter
A new view is created using the new represented object and displayed
The selected (parent) node and its children is reloaded in the NSOutlineView
The newly created row in the NSOutlineView is scrolled to view which synchronizes the view and the selection of the NSOutlineView
So here is the problem. The NSOutlineView will not find the newly added item if you use the rowForItem method. Yet after I reload I can expand the parent node and select the newly added item and everything works fine. In an attempt to fix the problem I have programmatically expanded the parent node (exposing the new item) then attempt to scroll to the new item and it still cannot find the row. The rowForItem returns -1.
Have I missed something when adding a new item that I am not updating something in the NSOutlineView? I've tried many different things without success and any help will be greatly appreciated.
Thanks in advance,
Rob
Solved my own problem...finally.
Since I was adding my first child to that node and it was changing from non-expandable to expandable it needed to be expanded first, then scroll to view, then select the item. No more problem.
