Pagination can be accomplished by using sequential Render() calls from http://docs.wxwidgets.org/trunk/classwx_grid.html
I understand How - sequential pages can be got from top left and bottom right coordinates.
But I dont get what needs to be the wxDC in the Render() call . ?
I want to get the first three rows in the grid
BigGridFrame::BigGridFrame(long sizeGrid)
: wxFrame(NULL, wxID_ANY, wxT("Plugin Virtual Table"),
wxDefaultPosition, wxSize(500, 450))
{
m_grid = new wxGrid(this, wxID_ANY, wxDefaultPosition, wxDefaultSize);
m_table = new BigGridTable(sizeGrid);
m_grid->SetTable(m_table, true);
//The above code gave me the table
//trying to get first three rows by render() function but it still gets the all of the grid values
**const wxGridCellCoords topLeft(0, 0);
const wxGridCellCoords bottomRight(3,4 );
wxClientDC clientDC(this); //this place I am not sure.. I couldnt find documentation
//m_grid->SelectBlock(topLeft, bottomRight, false);
m_grid->Render(clientDC, wxDefaultPosition, wxDefaultSize, topLeft, bottomRight, wxEXPAND);**
}
The DC is whatever you want to render the grid on, typically a wxMemoryDC to save the grid as a bitmap. This can't be used to partially render the grid on screen, which you appear to want to do, because it's just a static snapshot of the control.
I also have really no idea how can the code using this->Render() above compile considering that this is a wxFrame* and not a wxGrid*.
I misunderstood Render() function .
For pagination, I used the same logic used in
Changing Size of Grid when grid data is changed

I have been running SpatialUnderstandingExample scene from holo-toolkit. Couldnt figure out how to place my objects into the scene. I want to replace those small boxes that comes default with my own objects. How can I do that?
Thanks
edit: found the draw box but how do i push my object there?
edit2: finally pushed an object at the position but still code is very complicated its messing up with the size and shape of my object. Will try to make it clean and neat.
It's been a while since I've looked at that example so hopefully I remember its method name's correctly. It contains a "DrawBox" method that is called after a successful call to get a location from spatial understanding. The call that creates the box looks something like this:
DrawBox(toPlace, Color.red);
Replace this call with the following (assuming "toPlace" contains the results from the spatial understanding call and "model" contains the model you are trying to place there):
var rotation = Quaternion.LookRotation(toPlace.Normal, Vector3.up);
// Stay center in the square but move down to the ground
var position = toPlace.Postion - new Vector3(0, RequestedSize.y * .5f, 0);
// instantiate the hologram from a model
GameObject newObject = Instantiate(model, position, rotation) as GameObject;
if (newObject != null)
{
// Set the parent of the new object the GameObject it was placed on
newObject.transform.parent = gameObject.transform;
}
I have a Document based Core Data app with an NSTreeController supplying the content to a view based NSOutlineView. I am "styling" (setting text colour, background colour etc.) the rows based on persistent "transformable" NSColor and NSFont attributes in my data model which the end use can modify. When a new row is popped up, it displays things with the colours/fonts set in the data model. Here is the delegate/datasource code that sets the row background colour:
- (void) outlineView:(NSOutlineView *)outlineView
didAddRowView:(NSTableRowView *)rowView
forRow:(NSInteger)row
{
// Get the relevant nodeType which contains the attributes
QVItem *aNode = [[outlineView itemAtRow:row] representedObject];
if (aNode.backColor)
{
rowView.backgroundColor = aNode.backColor;
}
}
However when the style attributes change I want the associated visible rows to be redrawn with the new style values. Each time a "style" attribute is changed, I am using NSNotificationCenter to send a notification to the Outline view delegate, with the model object whose row needs to be redrawn with the changed style. This is the code in the delegate that receives the notification.
-(void) styleHasChanged: (NSNotification *)aNotification
{
NSTreeNode *aTreeNode = [myTreeController treeNodeForModelObject:aNotification.object];
[myOutlineView reloadItem:aTreeNode];
}
My assumption here is that I can navigate the tree controller to find the tree node which is representing my model object and then ask the outline view to redraw the row for that tree node. This is the "additions" code in the tree controller which walks the tree to find the object - not super efficient, but I don't think there is another way.
#implementation NSTreeController (QVAdditions)
- (NSTreeNode *)treeNodeForModelObject:(id)aModelObject
{
return [self treeNodeForModelObject:aModelObject inNodes:[[self arrangedObjects] childNodes]];
}
- (NSTreeNode *)treeNodeForModelObject:(id)aModelObject inNodes:(NSArray*)nodes
{
for(NSTreeNode* node in nodes)
{
if([node representedObject] == aModelObject)
return node;
if([[node childNodes] count])
{
NSTreeNode * treeNode = [self treeNodeForModelObject:aModelObject inNodes:[node childNodes]];
return treeNode;
}
}
return nil;
}
So sometimes this works and the row redraws, and sometimes it doesn't. The delegate method "styleHasChanged:" is always called, and the tree controller always returns a corresponding tree node (Actually of a subclass of NSTreeNode). But more often than not the outline view does not recognise the tree node, and the row is not redrawn. Its like the tree controller has given back a different tree node object to the one it gave the outline view in the past. But weirdly sometimes it does work and the right row is redrawn with the new background colour. If I collapse the row out of view and pop it open again, it is redrawn correctly.
Anyone any idea why it works sometimes and not other times?
It would be nice to be able to bind the colour/font attributes to the row and columns in some way, so that the outline view did this styling automatically with KVO, but I don't think that is possible - is it?
You spend hours/days trying to work out what you've done wrong; You write the question out; Post it; Sleep on it; and think how stupid can you be.
So I asked the NSTableRowView to redraw itself, but I had not set the new background colour. So here is the new improved (and works) version of styleHasChanged:
-(void) styleHasChanged: (NSNotification *)aNotification
{
QVItem *modelItem = aNotification.object;
NSTreeNode *aTreeNode = [myTreeController treeNodeForModelObject:modelItem];
NSInteger rowIndex = [myOutlineView rowForItem:aTreeNode];
if !(rowIndex == -1)
{
NSTableRowView *rowViewToBeUpdated = [myOutlineView rowViewAtRow:rowIndex makeIfNecessary:YES];
rowViewToBeUpdated.backgroundColor = modelItem.backColor;
}
}
Duh!
I am using Pentaho cde 4.8
I need to show Sparkline and Arrow in my Table component, I am using pagination in my table component.
My sparkline and arrow chart is visible While dashboard is loaded at first. Table component will show 10 rows per page and it will show all the charts as per my column type.
The problem occurs here, if I try to navigate to second page using pagination in my table then the charts are not shown and it will only show the values in the column. the same happens during when I use search bar in my Table component.
This is code I use in preexecution:
function f(){
this.setAddInOptions("colType","trendArrow",function(state){
return {
includeValue: true,
good: function(state) { if(state.value<=100) return false; else return true;}
};
});
}
I can see sparkline and trend arrow during 1st load like below:
After page navigation, it becomes like this
Avinash,
Try using Draw function.
The same code of preexecution is to be copied in Draw function.

I'm using Dialog and would like to style all my cells. I have a background image, and in the samples I can see how you can use a StyledStringElement to use that image.
However, in real use some sections use other elements. For example the last element in one section is a RootElement - but it has no BackgroundUri property to set. The same would go for boolean elements.
I found this question - What's the best way to customise all monotouch.dialog TableViewCells to the same style (Background, etc..)? which is a similar question a year and a half back. The UIAppearance styling mentioned does exist for tablecells but does not work with MTDialog. krtrego's answer to this In monotouch.dialog can RootElement be easily styled? question purports to do the job, but no styling occurred when I implemented it.
Is there now any improved way to do this? Implementing my own 'styled' versions of these other control types would be a big effort and looking at the styledstringelement this is beyond my current skill level.
Here's an example of what I'd like to achieve (the shadow below the 'tags' cell, but the element is actually a RootElement with a set of radio options beneath it). Removing the default grey lines etc is easy enough, but putting a subtle shadow on the bottom cell of each section is what I cannot work out.
Many thanks!
PS. With a normal MTDialog screen with cell backgrounds and borders removed, there is a subtle white shadow/line beneath each section as it is. If I could just recolour that I'd be a long way to where I want to be...
Subclassing the element will let you style it via overriding the GetCell method, but that gets pretty tedious. The best solution I have come across is to to make a custom DialogViewController by subclassing it, and overriding the CreateSizingSource method with your own SizingSource and GetCell() methods using the images you want for each scenario of a cell (top, middle, bottom, alone). Its a bit of code and my example wont handle uneven rows, but it is the only solution I have seen that does not modify the MT.D source code.
Here is what you would override in your DialogViewController subclass:
public override Source CreateSizingSource(bool unevenRows)
{
return new CustomSource(unevenRows);
}
Then you would make a custom source class:
public class CustomSource : Source
{
public CustomSource(DialogViewController parent) : base (parent)
{
}
public override UITableViewCell GetCell(UITableView tableView, NSIndexPath indexPath)
{
var theCell = base.GetCell(tableView, indexPath);
if (RowsInSection(tableView, indexPath.Section) == 1) //use one with top and bottom rounded
{
theCell.BackgroundView = new UIImageView(Theme.CellBackgroundFull);
theCell.SelectedBackgroundView = new UIImageView(Theme.CellBackgroundFullActive);
} else if (indexPath.Row == 0) //top only
{
theCell.BackgroundView = new UIImageView(Theme.CellBackgroundTop);
theCell.SelectedBackgroundView = new UIImageView(Theme.CellBackgroundTopActive);
} else if (indexPath.Row+1 == RowsInSection(tableView, indexPath.Section)) // bottom only
{
theCell.BackgroundView = new UIImageView(Theme.CellBackgroundBottom);
theCell.SelectedBackgroundView = new UIImageView(Theme.CellBackgroundBottomActive);
} else //anything in the middle
{
theCell.BackgroundView = new UIImageView(Theme.CellBackgroundMiddle);
theCell.SelectedBackgroundView = new UIImageView(Theme.CellBackgroundMiddleActive);
}
return theCell;
}
}
Theme is just a static class that returns UIImages, similar to the example Field Service app from Xamarin. So here I have made 8 images total. 4 to represent the top, middle, bottom and alone for an element. Each has different rounded corners to appear correct. And then a "highlighted" version of each for when its touched.
The big drawback here is you have to do this for every different styled controller you would need. If you are ok with modifying the MT.D source code, you can get a different solution that will allow you to control it at the Section level here: http://fastchicken.co.nz/2012/05/20/earnest-debrief-visual-styles-in-ios-apps-uiappearence-custom-sections-in-monotouch-dialog/
Which has the same effect, but you only need to subclass Section for each different style, which makes including multiple styles in one Root easier. A pull request was made for this change, but Miguel favored the first solution instead, seen here: https://github.com/migueldeicaza/MonoTouch.Dialog/pull/180
I've created a simple mapping widget using Dojo and Google Maps. The map is displayed in a dijit.layout.ContentPane set as the center panel of a dijit.layout.BorderContainer (which has the address field and a BusyButton in its top panel); the BorderContainer is in turn wrapped in a dojox.layout.FloatingPane. The widget has a subscription to a topic that will trigger a refresh of the map display when new address data is provided. The updater function is very simple, and looks like this:
_updateAddress: function(data) {
this.addressMapper.show();
if (data === null || !data.address || data.address === "" ) {
this.address.attr("value", "");
} else {
this.address.attr("value", data.address);
}
this.mapBtn.makeBusy();
this._getMap();
}
Every time I call this function, the FloatingPane's resize() method is invoked when I call show(), and it's increasing the height and width of the BorderContainer by 12 pixels every time the pane is shown (even with doLayout and isLayoutContainer set to false on the FloatingPane). I can't seem to prevent this from happening, or correct it afterwards, no matter what I try.
Anyone have any ideas how to remedy this?
Thanks in advance!
