A list with 3 columns. First column for show/hide, second for the model name and the third for lock/unlock that will only appear when the item is clicked.
How do you create something like this using QTableWidget and QStyledItemDelegate? I have been looking at the documentations and some questions and I still find it hard to understand.
I have a grid with 10 columns, and another with over 60. I want to offer a view of these grids where any column or number of columns can be selected to remain visible. Then submit a request to hide all of the remaining 'UN-selected' grid columns, leaving the selected columns viewable.
End-users need to have a mechanism where they can choose which column(s) to view and the remaining columns will be hidden temporarily from view. I know that I can choose each column from the context menu to hide each column, but if I have a grid with multiple columns it can be quite difficult to select each column to hide. I would like to create a mechanism where users can select which columns they want to 'view' and allow the remaining columns to hide.
I believe that grid reconfigure may be the way to go, but there are no real examples showing how I might select the columns to allow viewable "on-the-fly", and then reconfigure the grid based on the new column model.
There are a couple of ways you could approach this:
One way would be to loop through the columns and call hide() method on those you wish to hide.
For a large number of columns it might be better to use reconfigure method. using reconfigure with the first paremeter undefined you get to reuse the store that was originally configured:
reconfigure( undefined, myColumns )
Hi,
I want to create a custome widget. Please help by giving some idea.
My intention is to make a Listwidget which shows some Information and when clicking particulat row it have to show the details coresponding to that row by creating a new area(Row or text edit) immediately below the selected row and pull the other rows below the selected row to down after the created new area.
In attachment when I click row Nancy (consider it as row) her details is coming below the selected row. Please help on this
What you want to use is the QTreeView. It is capable of showing rows with text and icons.
You need to define the QStandardItemModel for the table, this will give it column definition.
Below are three relevant functions from a class I wrote for a similar app. Note that I did not need to use any images in my rows so you'll have to figure that part out yourself.
def drawPeopleListBox(self):
header = ["Picture","First Name","Last Name","Title","Address", "City", "Region"]
self.model = QStandardItemModel(0, len(header), self)
for i in range(len(header):
self.model.setHeaderData(i, Qt.Horizontal, self.selectionDict[i+1].upper())
self.itemList = QTreeView()
self.itemList.setRootIsDecorated(False)
self.itemList.setAlternatingRowColors(True)
self.itemList.setSortingEnabled(False)
self.itemList.setModel(self.model)
self.itemList.NoEditTriggers=True
#self.itemList.clicked[QModelIndex].connect(self.onRowClick)
self.itemList.clicked.connect(self.onRowClick)
self.itemList.setCursor(Qt.PointingHandCursor)
self.itemList.setColumnWidth(0,70)
self.itemList.setColumnWidth(1,140)
self.itemList.setColumnWidth(2,70)
self.itemList.setColumnWidth(3,180)
self.itemList.setColumnWidth(4,100)
self.itemList.setColumnWidth(5,100)
self.itemList.setColumnWidth(6,100)
self.populateList(self.userDataList)
def populateList(self, userDataList):
row=[]
for user in userDataList:
for attrib in user:
row.append(QStandardItem(attrib))
for item in row:
item.setEditable(False)
self.model.appendRow(row)
def onRowClick(self, index):
print index.row()
'''
Here you need to resize the clicked row height. Also resise the image.
Or insert another row that matches your design requirement.
self.model.insertRow(rowNumber, listOfQStandardItems)
'''
self.repaint()
You may want to try using a custom delegate to view the rows. I believe the delegates know if they are selected. Using this, you would draw the unselected rows normally, and draw more information for the selected rows. The problem with this is that I don't know if you can resize the widget on selection. If not, the QTreeView solution should still work.
I am a new of flex , i have four columns and five rows of datagrid . i want know how to add color overlay of wipeleft or wiperight on each row of datagrid. when i click which row then i got that wipe action.
Thanks advance
senthil.
If you can get those "wipeleft or wiperight" events than you just need to use drawRowBackgrounds() method as mentioned in this topic.
I am creating an application in asp.net..I used a grid view to show the datas .. By using the autogenerate columns
I bind the datas to the gridview.. Now i want to make a edit button at the end ..By clicking that the user can edit their details ...
But i need to count the number of columns in a row to make a pop up window to edit the details.. How to find out the number of columns in a autogenerated grid..Number of columns varies depend upon the user..So how to find the number of columns..
You will get the no of columns through like this
int NoOfColumns=GridView1.Rows[0].Cells.Count;
You can find,
How many columns are in gridview with
GridView1.Columns.Count
How many cells are in one row of gridview with
GridView1.Rows[..].Cells.Count
