I want to simulate a drag and drop functionality from one DevXtraGridcell to another DevXtraGridcell without using the coordinate system.
Can someone give me an idea how can I do it without the default record and play and without the source and destination cordinates.
The Drag action always uses coordinates, but you can calculate the coordinates on the fly instead of using hard-coded coordinates:
Explore your grid in TestComplete's Object Browser and find a method or property that returns cell coordinates.
According to this old blog post, it should be something like:
gridObj.MainView.ViewInfo.RowsInfo.GetInfoByHandle(Row).Cells.Item_2(Column).Bounds
Calculate the coordinates of the first and second cell. (Make sure that both cells are visible on the screen.)
Do the Drag from one first cell's coordiantes to the second cell's coordinates.
in my case i had to user the obj.MainView.get_ViewInfo property worked for one gridcontrol , the other is of card layout the link given doesnt work in my case though

I would like to make an animation of a growing 2D object in ParaView. I already found the follow the data filter for the camera, but this just centers the object throughout the animation. What I want is that the camera always zooms to the data to show the growing object in full size. Is there a way to do this in ParaView? Thank you!
In the Animation View, add a Python track. Double-click the track to edit the Python, and enter
from paraview.simple import *
def start_cue(self): pass
def tick(self):
GetActiveView().ResetCamera()
def end_cue(self): pass
This should reset your view to see all the data.
I believe you can achieve what you want using a interpolation.
Select "View"(Alt+V) then "Animation View". A dock window will open under the Layout.
Select "Camera" from the dropdown menu, then select "Interpolate Camera Location".
Choose the first and last camera places in a way your data will always be fully visible. Then hit play to see result =)
If I subclass QLabel and I add a QLabel directly to my QDialog, it works fine. If I add this label inside a ScrollArea, the thing I’m drawing doesn’t show unless I resize the dialog itself. Yes, weird.
I’ve setup compilable example code that indicates what the problem is. What I am trying to do is to select an area of an image with my mouse, by drawing a rectangle on the corresponding area. The images my program is designed to work with can be very large, and thus, I need to have a scroll area so as the dialog to stay at a logical dimension, and not to fill the entire screen (or even multiple workspaces, if we are talking about a linux machine with multiple desktops).
Everything works fine, except that the drawing (selection-rectangle) isn’t visible unless the dialog is resized – manually. I think I have to update something while drawing, but I’m not sure what. Well, here’s the example code: http://paste.ubuntu.com/1151553/
Another issues that I don’t know how to solve (and I want your suggestions there) are (1) when the user is selecting an area, how to set it to automatically scroll when the user actually selects an area by pushing against to a wall of the scroll area (I guess I am understandable here). (2) is there a way to let the user select a rectangle and then, when he left-clicks on a position with holding down the [Shift] button, the bottom right edge of his previous selection to actually go through the point he clicks at?
The documentation indicates that you have to set a Layout somehow somewhere, but I'm not sure how to do this to my occassion.
Thanks in advance for any help.
about problem (1):
just use of Event. i think mouse Enter Event or Leave Event is good for that.
and to do that i think you can use a hidden rectangular that fill the whole of the screen.
and over write the mouse leave Event for that rectangular and tell in that function , to scroll the page.
I want to know exactly where I am placing my images programatically, and therefore need to know the coordinates of my storyboard.
Is there a way to view these from the interface builder in Xcode?
Your workspace dimension is 320X460 suppose you want to add a button programmatically first go into IB and place a button where you want it to be and then in the right side check the coordinates of button in show the size inspector and use those coordinates in your code this will give you a fair idea about where your button will go after you add it programmatically... hope this will help you
NO. Use your imagination. Programmatically added visual objects cannot be seen in IB.
Instead, you could place an object in IB, adjust it's position to the desired one, read it's frame, delete it from IB, and use it's frame values to programmatically add id.
I have a xcode/ipad application that adds buttons at runtime at the touch point on the screen.
Now I need to remove these button(s) at runtime by only using the x/y coordinates.
How do I accomplish this??
take care
tony
not the best and fastest way to do it, but iterate over the parent view's control list, find out their relative x/y coordinates and remove them from the parent view
I'm trying to make the cells of a QTableView look like 3D clickable buttons. So that when you click on a cell, the button looks pushed. Everyone seems to think I merely want to change the colour, I need to show images of a normal button, and a pushed button, that look 3-dimensional.
I have done this already with calling QTableView::setItemDelegate(), with an appropriate ItemDelegate that will change the background of the cell when it's clicked. However I'm stuck at this point because I want some cells to be different coloured buttons based on the data they contain. So a cell with a low number would be a red button, that's also red when it's clicked, and the other cells would be different colours.
I can set the colour of the button with the TableModel, but once the button is clicked, there is no way for the ItemDelegate to know that it's supposed to be a different colour than the rest. How can you link the two so the ItemDelegate knows what colour it's supposed to be?
Also, is there simply a better way to make cells look like buttons?
You can call QModelIndex::model() from within the ItemDelegate's paint() method, since it has a QModelIndex parameter. This gives you the TableModel for the data, which you can programatically decide what colour the cell's button will be.
However, this is still not as elegant as I'd hope. Does anyone know a better way to change the appearance of table cells when in both the up and down button push states?
Why don't you asked the index for the background color.
Something like this ...
QStyleOptionToolButton buttonOption;
const QStyleOptionViewItemV4& optionV4 = dynamic_cast<QStyleOptionViewItemV4&>(option);
//...
buttonOption.palette.setBrush( QPalette::Button, index.data( Qt::BackgroundColorRole ) );
//...
I have feeling that its a bug in Qt and its must have been ...
// model code
if(role==Qt::BackgroundColorRole )
return qvariant_cast<QBrush>( QBrush(Qt::red) );
// delegate code
buttonOption.palette.setBrush(QPalette::Button, optionV4.backgroundBrush );
Because the optionV4.backgroundBrush is correct in the sizeHint method but is invalid in the paint method . I see now reason why the sizeHint should have the background brush and the paint method not. I'll report it to Nokia.
EDIT:
Looks like I was right and its a bug in < Qt4.5.
QStyleOptionViewItemV4 doesn't copy the icon and backgroundBrush
Can you not get the ID/row count of the table cell's row and then check it against the colour table that you may be having, and set the colour accordingly? I am not sure if I understood your question well or not.
Assign a data role for the background color, and in your item delegate, ask the model index what it's background color is (using data( bg_color_role ) or something similar). Then, in your model, you need to make sure the data function returns a color for the bg_color_role that is appropriate for the data being modeled.
The way to do that is to use the data method of the QModelIndex object you get on the paint method, and ask for a specific role (if you define a custom model, you can add your own roles, and give the information you need to the delegate in those roles.)
TimW, I think you have to fill the QStyleOptionViewItemV4 info by calling initStyleOption before.
I'm not sure where the requirement for a background image comes from. If you want the cells to look like QPushButtons, you should probably inherit from QItemDelegate and implement paint() to use QStyle to draw you a QPushButton, something like this:
QStyleOptionButton opt;
// fill 'opt' from the information from the model, and the style option that's passed in
style()->drawControl( QStyle::CE_PushButton, &opt, painter );
Have you tried using custom style sheets?
You could just apply the same stylesheet to every cell, and then change the background image / style to draw the 3D button images depending on whether or not it's selected.
