  • Trying to retrieve the contents of UITableView cell on selection by user.

    - by chubsta
    Hi, this is my first post here and as i am very new (2 weeks in...) to iPhone (or any!) development i am a little unsure as to how much detail is needed or relevant, so please forgive me if I dont provide enough to be useful at this stage... Anyway, on to my problem - I have set up a UITableView-based app, which has a .plist for holding the data. The .plist has a dictionary as its root, followed by a number of Arrays, each containing the data-strings that display in the table. Everything is working fine until the point where i select a row. I have set it up so i get an alert with the results of the button press and it is here that i want to see the contents of the cell being produced. Instead of the expected string eg. "data line 1", all i get is the number of the row within the section. I have gone backwards and forwards but dont seem to be getting anywhere although i am sure it is something simple. The code compiles fine, with no warnings or errors, and if i can just get the string of the selected cell i will be well on my way, so any help appreciated. I know that I need to do more following the 'NSUInteger row = [indexPath row]; part but thats where my mind dries up... here is the relevant 'selection' section, if i need to post more code please let me know, and i really appreciate any help with this...(please forgive my 'alert' message, i was just happy at that point that i get SOMETHING back from the row selection!) (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath { [tableView deselectRowAtIndexPath:indexPath animated:YES]; NSUInteger row = [indexPath row]; NSString *message = [[NSString alloc] initWithFormat: @"You selected Cell %d from this Section, "@"which is a very good choice indeed!" @"Unfortunately I can't work out how to get the info out of the cell so it's not much use at the moment!" @"Still, this is a good chance to see how much space I have in an alert box!", row]; UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"My God! It works..." message:message delegate:nil cancelButtonTitle:@"You are awesome Karl!!" otherButtonTitles:nil]; [alert show]; [message release]; [alert release]; }

  • How to make selection color be "on top" when background color for any text element is set in Visual

    - by Confused Developer
    Faced problem while setting background color for any element in Visual Studio 2010 editor. Selection color doesn't override this background color. So then it's very inconvenient to work with selections in editor. Case when only string literal is selected it's almost impossible to distinguish colors and see what part of string is selected. Is there any possibility to fix the problem by changing some options? Or it's a Visual Studio bug?

  • Prevent custom AccessoryView from showing selection when it's UITableViewCell is selected.

    - by groomsy
    To reproduce this, create a UITableView that contains cells with custom AccessoryViews (such as buttons to perform a specific action where touching the other part of the UITableViewCell should perform a different action). If you touch (select) the UITableView, the AccessoryView shows selection (as thought it was touched) as well. I want to prevent this and only show the AccessoryView's selected state when they actually touch the AccessoryView. Thanks in advance, groomsy

  • Does Resharper 4.1 support both Camel Humps and normal selection modes?

    - by Jonathan Parker
    I've found the setting for Camel Humps in resharper: Resharper - Options - Editor - Use CamelHumps The problem is that I would still like to be able to use the normal selection mode (i.e. the default behaviour for CTRL+Arrow and CTRL+SHIFT+Arrow) as well as the CamelHumps mode. For example consider this variable: private int MyVeryLongCamelCaseName; Now if I want to copy the entire variable then I want the VS default behaviour for CTRL+SHIFT+Left-Arrow which is to select the entire variable if the cursor is on the M. However if I want to change the name to say MyExtremelyLongCamelCaseName then I would like the CamelHumps behaviour provided by Resharper. Is there any way to have both behaviours with different shortcuts?

  • How do I get HTML Markup for createRange() in Firefox

    - by OneNerd
    I am currently using code similar to this: try { // IE ONLY var theElement = "myElementName"; window.frames[theElement].focus(); var selection = window.frames[theElement].document.selection.createRange(); alert ( selection.htmlText ); } catch(e) { var selection = window.frames[theElement].document.getSelection(); alert ( selection ); } As you can see, I am accessing a node from an iframe (no fun already). I am definitely in new territory here, so am sure there are more issues to arise, but right now, I am trying to get Firefox to give me the same result as IE. In IE, I can access the HTML code of the selection by using the (apparently IE-only) htmlText property of the object returned by createRange(). What I am looking for is the Firefox equivalent to that (or a function that I can use to give me the same result). Anyone know how to do this?

  • How do I Transpose with the 10,000 row limits of excel?

    - by ezlee69
    I am trying to Transpose all of column "B", but want to skip a line then grab the next 4 and paste them in the same column. How can I make this loop all of column "B" skipping every 5th line and change the range to the next open cell or "Range" automatically without manually typing each one individually? Range("B12:B16").Select Selection.Copy Sheets("Sheet2").Select Range("A2").Select Selection.PasteSpecial Paste:=xlPasteAll, Operation:=xlNone, SkipBlanks:= _ False, Transpose:=True Range("B18:B22").Select Selection.Copy Sheets("Sheet2").Select Range("A3").Select Selection.PasteSpecial Paste:=xlPasteAll, Operation:=xlNone, SkipBlanks:= _ False, Transpose:=True Range("B24:B28").Select Selection.Copy Sheets("Sheet2").Select Range("A4").Select Selection.PasteSpecial Paste:=xlPasteAll, Operation:=xlNone, SkipBlanks:= _ False, Transpose:=True

  • In GWT-EXT checkboxtree how to handle single selection of tree nodes?

    - by RAS
    hi, I'm working on checkBoxTree in GWT-EXT 2.0.3 with Java. My aim is to get a selectionModel which allows me to select(check) only one TreeNode at a time. If I select another TreeNode after selecting one then, the previous one should be unchecked. I've tried using DefaultSelectionModel with TreePanel, but either I've not used it properly or it's working only for selection of TreeNode not for checking a TreeNode. Can anyone help me in this? Thanks in advance.

  • PyGTK: Radiobuttons are still displayed after removal

    - by canavanin
    Hi everyone! I am using PyGTK and the gtk.assistant. On one page I would like to display two radiobuttons in case the user selected a certain option on a previous page. The labels of the buttons - and whether the buttons are to be present at all - are to depend entirely on that earlier selection. Furthermore, if the user goes back and changes that selection, the page containing the radiobuttons is to be updated accordingly. I have got as far as having the radiobuttons displayed when necessary, and with the correct labels. The trouble is that if I go back and change the determining selection, or if I move one page further than the 'radiobutton page' and then move back, the buttons are not only not removed (in case that would have been required), their number has also doubled. To show you what I'm doing, here's part of my code (I've left out bits that do unrelated things, that's why the function name doesn't fit). The function is called when the "prepare" signal is emitted prior to construction of the 'radiobutten page'. def make_class_skills_treestore(self): print self.trained_by_default_hbox.get_children() # PRINT 1 for child in self.trained_by_default_hbox.get_children(): if type(child) == gtk.RadioButton: self.trained_by_default_hbox.remove(child) #child.destroy() # <-- removed the labels, but not the buttons print self.trained_by_default_hbox.get_children() # PRINT 2 class_skills = self.data.data['classes'][selected_class].class_skills.values() default_trained_count = (class_skills.count([True, True]) , class_skills.count([True, False])) num_default_trained_skills = default_trained_count[1] / 2 # you have to pick one of a pair --> don't # count each as trained by default for i in range(default_trained_count[0]): # those are trained by default --> no choice num_default_trained_skills +=1 selected_class = self.get_classes_key_from_class_selection() if default_trained_count[1]: for skill in self.data.data['classes'][selected_class].class_skills.keys(): if self.data.data['classes'][selected_class].class_skills[skill] == [ True, False ] and not self.default_radio: self.default_radio.append(gtk.RadioButton(group=None, label=skill)) elif self.data.data['classes'][selected_class].class_skills[skill] == [ True, False ] and self.default_radio: self.default_radio.append(gtk.RadioButton(group=self.default_radio[0], label=skill)) if self.default_radio: for radio in self.default_radio: self.trained_by_default_hbox.add(radio) self.trained_by_default_hbox.show_all() self.trained_by_default_hbox and self.trained_by_default_label, as well as self.default_radio stem from the above function's class. I have two print statements (PRINT 1 and PRINT 2) in there for debugging. Here's what they give me: PRINT 1: [<gtk.Label object at 0x8fc4c84 (GtkLabel at 0x90a2f20)>, <gtk.RadioButton object at 0x8fc4d4c (GtkRadioButton at 0x90e4018)>, <gtk.RadioButton object at 0x8fc4cac (GtkRadioButton at 0x90ceec0)>] PRINT 2: [<gtk.Label object at 0x8fc4c84 (GtkLabel at 0x90a2f20)>] So the buttons have indeed been removed, yet they still show up on the page. I know the code requires some refactoring, but first I'd like to get it to work at all... If someone could help me out that would be great! Thanks a lot in advance for your replies - any kind of help is highly appreciated.

  • how do I disable options based on the previous selection?

    - by 3r1c
    I have three drop-down menus for each sample shirt; product, colour and grade. Not all products are available in all colours and/or grades. I would like to disable the options that are not available based on the users selection. I've tried using this answer here (using a radio select). Unfortunately, I can't get it to work with an option-selected input. This is what I'm working on - quartus.ca/select-options.html Any guidance would be appreciated.

  • WPF Toolkit Datagrid - how do you turn selection off?

    - by RodH257
    I have a datagrid in WPF that I am binding to an object. I have a DataGridCheckBoxColumn on there which I want the users to be able to go through and tick the ones they want. Problem is they have to click twice, once for selection then again to check/uncheck. How on earth do you turn this off, I've been searching for way to long to find the answer to this. The datagrid has SelectionMode and SelectionUnit properties - neither of which accept 'none' or 'go away' Any help is appreciated! My code is below for reference <my:DataGrid Margin="15" Name="dgPreview" AutoGenerateColumns="False" CanUserSortColumns="True" CanUserDeleteRows="True" Background="White" ColumnHeaderHeight="20" VerticalScrollBarVisibility="Visible" RowDetailsVisibilityMode="Visible" > <my:DataGrid.Columns> <my:DataGridCheckBoxColumn MinWidth="50" Width="Auto" Header="Include" Binding="{Binding Include}" /> <my:DataGridTextColumn MinWidth="50" Width="Auto" Header="Override #" Binding="{Binding OverrideNumber}" /> <my:DataGridTextColumn MinWidth="220" Width="*" Header="Name" Binding="{Binding Name}" /> <my:DataGridTextColumn MinWidth="50" Width="Auto" IsReadOnly="True" Header="Preview" Binding="{Binding Preview}" /> </my:DataGrid.Columns> </my:DataGrid>

  • AutoCompleteTextView displays 'android.database.sqlite.SQLiteCursor@'... after making selection

    - by user244190
    I am using the following code to set the adapter (SimpleCursorAdapter) for an AutoCompleteTextView mComment = (AutoCompleteTextView) findViewById(R.id.comment); Cursor cComments = myAdapter.getDistinctComments(); scaComments = new SimpleCursorAdapter(this,R.layout.auto_complete_item,cComments,new String[] {DBAdapter.KEY_LOG_COMMENT},new int[]{R.id.text1}); mComment.setAdapter(scaComments); auto_complete_item.xml <?xml version="1.0" encoding="utf-8"?> <TextView xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/text1" android:layout_width="wrap_content" android:layout_height="wrap_content"/> and thi is the xml for the actual control <AutoCompleteTextView android:id="@+id/comment" android:hint="@string/COMMENT" android:layout_width="fill_parent" android:layout_height="wrap_content" android:textSize="18dp"/> The dropdown appears to work correctly, and shows a list of items. When I make a selection from the list I get a sqlite object ('android.database.sqlite.SQLiteCursor@'... ) in the textview. Anyone know what would cause this, or how to resolve this? thanks Ok I am able to hook into the OnItemClick event, but the TextView.setText() portion of the AutoCompleteTextView widget is updated after this point. The OnItemSelected() event never gets fired, and the onNothingSelected() event gets fired when the dropdown items are first displayed. mComment.setOnItemClickListener( new OnItemClickListener() { @Override public void onItemClick(AdapterView<?> arg0, View arg1, int arg2, long arg3) { // TODO Auto-generated method stub SimpleCursorAdapter sca = (SimpleCursorAdapter) arg0.getAdapter(); String str = getSpinnerSelectedValue(sca,arg2,"comment"); TextView txt = (TextView) arg1; txt.setText(str); Toast.makeText(ctx, "onItemClick", Toast.LENGTH_SHORT).show(); } }); mComment.setOnItemSelectedListener(new OnItemSelectedListener() { @Override public void onItemSelected(AdapterView<?> arg0, View arg1, int arg2, long arg3) { Toast.makeText(ctx, "onItemSelected", Toast.LENGTH_SHORT).show(); } @Override public void onNothingSelected(AdapterView<?> arg0) { // TODO Auto-generated method stub Toast.makeText(ctx, "onNothingSelected", Toast.LENGTH_SHORT).show(); } }); Anyone alse have any ideas on how to override the updating of the TextView? thanks patrick

  • How to implement Master-Detail with Multi-Selection in WPF?

    - by gehho
    Hi, I plan to create a typical Master-Detail scenario, i.e. a collection of items displayed in a ListView via DataBinding to an ICollectionView, and details about the selected item in a separate group of controls (TextBoxes, NumUpDowns...). No problem so far, actually I have already implemented a pretty similar scenario in an older project. However, it should be possible to select multiple items in the ListView and get the appropriate shared values displayed in the detail view. This means, if all selected items have the same value for a property, this value should be displayed in the detail view. If they do not share the same value, the corresponding control should provide some visual clue for the user indicating this, and no value should be displayed (or an "undefined" state in a CheckBox for example). Now, if the user edits the value, this change should be applied to all selected items. Further requirements are: MVVM compatibility (i.e. not too much code-behind) Extendability (new properties/types can be added later on) Does anyone have experience with such a scenario? Actually, I think this should be a very common scenario. However, I could not find any details on that topic anywhere. Thanks! gehho. PS: In the older project mentioned above, I had a solution using a subclass of the ViewModel which handles the special case of multi-selection. It checked all selected items for equality and returned the appropriate values. However, this approach had some drawbacks and somehow seemed like a hack because (besides other smelly things) it was necessary to break the synchronization between the ListView and the detail view and handle it manually.

  • How can I enable child inputs text selection in Mozilla Firefox using CSS?

    - by L. Shaydariv
    Hi. Let consider the following scenario. I have the following page where all rendered elements must be non-selectable. <html> <head> <style type="text/css"> body { -webkit-user-select: none; -moz-user-select: none; } div { border: solid 1px green; padding: 5px; } </style> </head> <body> <div> Lorem ipsum dolor sit amet, consectetuer adipiscing elit, sed diam nonummy nibh euismod tincidunt ut laoreet dolore magna aliquam erat volutpat. Ut wisi enim ad minim veniam, quis nostrud exerci tation ullamcorper suscipit lobortis nisl ut aliquip ex ea commodo consequat. Duis autem vel eum iriure dolor in hendrerit in vulputate velit esse molestie consequat </div> <div> <input type="text" value="You can select the text from me" /> <textarea> And me too. </textarea> </div> </body> </html> The input and textarea text is still selectable in Google Chrome, but the text is not selectable in Firefox. I've already tried the following: input, textarea { -moz-user-select: text !important; } And... It simply doesn't work because (as far as I can see) input and textarea are nested in the document body element that's already is not selectable. So, is it possible to enable text selection of the nested user input elements in Firefox using CSS? Thank you for suggestions.
