• object visible only when the mouse over it

  Hi guys

  I'll try to find a way to perform this action

  How to make an object invisible but when the mouse is in this area, it appears

  I mean it's white page and there is an object

  Thank you..

  You can either set its visible to false, but don't forget the rectangle, then keep checking to see if the mouse is inside this rectangle. Or an easier way would be to set its alpha to 0 and a normal mouse event to set the alpha to 1 when the user points in this area.

• DW CS6 test server shows only the login screen of my site. Can't do under the hood live wiew. The pages I want to change/modify is visible only when I connect but I do not know how to reolve that.

  I'm trying to edit a CMS site to my needs and "open" pages is not serious, that is to say those that do not require the user to connect to. I can see and I can modify them according to my needs.

  The trickiest part is when I want to change/modify something inside. Then it wont let me. The only thing I see is the "Login" screen I can see the code and I can do what I need, but when I turn on 'Live wiew' is the log in page that greets me

  
  Tests of servers is correct because I can use it in my localhost

  Connection MySQL works as it should (Test OK)

  I guess that's something that has to do with permissions, but I don't know what.

  A CMS site, the page is usually filled with data that is stored in a database using a scripting language on the server side. Unfortunately, the Design mode only supports a static language like HTML, there is therefore no recovery information from the database.

  The only way out of your situation is to temporarily remove the permission to the user to the page that you are editing so that you do not to log-in each time. The problem is that you may forget to reactivate the authorization.

  What I always do is to open the site in a browser and verify the change in DW refreshing the page in the browser. In this way, you need to log-in once.

• button is active, but only when it is visible?

  Hello

  I try to get a few buttons to work I have in a timeline. These buttons are on each other and are called to be visible only when a certain image.

  My problem is the button in the foreground is the only asset, because all the buttons are "on", even if you do not see them.

  currently buttons are on alpha.0 at the beginning. I know there's a way for them to is active only when they are visible, but I can't find the documentation.

  Does anyone know this code and how?

  I have my code began as such:

  import flash.events.MouseEvent;

  import flash.ui.Mouse;

  bfButton.buttonMode = true;

  bfButton.useHandCursor = true;

  and I also have this:

  bfButton.alpha = 0

  While the buttons go up I bring alpha 1 over a period of time, but there is a trick for visibility and I can't understand it.

  any help would be GREATLY appreciated.

  Thank you!

  You can use combinations of things.  You can use the visible property as well as the alpha property.  You can also try using the property mouseEnabled with the alpha property.  In both cases, you must put true and false if necessary while still making your alpha interpolation.

• Show LOV only when the field is empty

  Hi all
  My surroundings:
  Oracle 10g on Windows
  Forms [32 bit] Version 9.0.4.1.0 (Production)
  Oracle Database 10 g Enterprise Edition Release 10.2.0.5.0 - 64 bit Production
  With partitioning, OLAP, Data Mining and Real Application Testing options
  Oracle Toolkit Version 9.0.4.1.0 (Production)
  PL/SQL Version 9.0.1.5.1 (Production)
  
  My problem:
  I have a field in a block, which is text_item and is linked to an element of LOV. I want the LOV appears automatically, whenever I tab in there, only when the element is EMPTY (for example when I try to insert in the block). When, upon request, it should show only the value in the field, and user can choose to activate the LOV, by pressing F9, if she wants to. It now displays automatically each time text agenda is a debate (works very well when the user is inserted, but annoying when she questioned the shape and trying to tab thru.) Every time she focuses on the field, LOV is popping up!)
  
  The current setting for the property on the element of text field: Type: text element
  The list of values: MY_LOV_NAME
  Validation of list: Yes
  
  Properties on MY_LOV_NAME
  Auto display: Yes
  
  Any suggestions? Or trigger level I can use, and if so, what build_in can use?
  New forms and will greatly appreciate advice from pros!
  
  Thank you
  Libran_girl

  It's very simple,

  IN once - new - item - Instance

  DECLARE
  V_LOV BOOLEAN;
  BEGIN
  IF: NOM_ELEMENT IS NULL
  THEN
  V_LOV = SHOW_LOV (LOV_NAME);
  END IF;
  END;

  Try it, you will get your result, if it doesn't work, try: block_name.item_name

• Displays the message if ListView is empty

  I create an application that will empty ListView when it is installed. I want to display a message 'No still images' on this subject, but I'm not sure of the best way.

  One way would be to add a point and have a custom ListItemComponent so that it displays the message. (Better), another is to have a label on the ListView that will be visible only if there are no elements.

  All the best ideas? I thought that there is a kind of way to do this by default like on Android.

  something like this works well

      Container {
          id: outerDock
          layout: DockLayout {
          }
  
          ListView {
              id: carrierList
              // ...
              dataModel: GroupDataModel {
                  id: carrierDataModel
                  // ...
              }
              listItemComponents: [
                  // ...
              ] // listItemComponents
              onTriggered: {
                  // ...
              }
          } // carrierList
          Container {
              id: bgContainer
              visible: false
              verticalAlignment: VerticalAlignment.Top
              Label {
                  text: qsTr(" No Data") + Retranslate.onLanguageChanged
                  textStyle.base: SystemDefaults.TextStyles.BigText

• How to detect when ListView recycles an ImageView?

  I have a ListView with items ~ 600 in a 4-wide grid. Each element is a WebImageView (inherits from ImageView, slightly modified from code kindly provided here) over a label.

  Everything works spot - we (and performance is awesome) except for one glaring problem: when I sometimes momentarily the ImageView ListView displays scrolling scrolls the erroneous image of an item that was previously on. Sometimes it moves even between two prior images before displaying the right pair. These problems are happening because applications for network WebImageView queues upward because the visible element has been recycled once or even twice.

  What I need to solve this problem is to know when the WebImageView has been recycled by ListView in order to disconnect the network signals and erase the old image. I can't find how to do this.

  So I have a "fix" that is more than a workaround. In the WebImageView, I added a member variable:

  int m_iCurrentRequestIndex;

  Whenever WebImageView has applied for a network, I add m_iCurrentRequestIndex as an attribute of the QNetworkRequest and then increment.

  When I receive the response from the network, I check if the value of attraibute for example a_reply-> request (.attribute (...)) and throw the answer if it is not the last.

  Not a very good solution because it is always that which allows network support needless to proceed and just throw the results, but at least it works. But if anyone can answer the question in the original post, I who brand as the solution because it will allow for better efficiency. I want to know a signal or something available at WebImageView that is called when ListView is recycled as:

  WebImageView::onRecycled()
  {
      // close() and disconnect() current QNetworkRequest().
  }
  

• Label visibility does not not with actionItem

  Hello

  I have a follow up on my page. I want to alternate the two labels of visibility on my page. So when I click on the action point first, I want the title to change the visibility of Label1 to disable and visibility of Label2 to switch on. And conversely, when I hit the actionitem twice.

  When I click on it the first time, changes in visibility (i.e. no visible = label1, label2 = visible and the title was changed to the action item).  However, it will not work the second time I click on the button - it remains fair to label2 = visible and the title for the action remains the same.

  Any ideas? Here is my code below:

  Page {
      id: pageID
      Container {
          id: rootContainer
          Label {
              visible: true
              id: label1
              text: "Label 1"
          }
          Label {
              visible: false
              id: label2
              text: "Label 2"
          }
      }
  
      actions: [
          ActionItem {
              id: actionitem
              title: "View Label 2"
              ActionBar.placement: ActionBarPlacement.OnBar
              onTriggered: {
                  if (label1.visible = true) {
                      label1.visible = false
                      label2.visible = true
                      actionitem.title = "View Label 1"
                  } else if (label2.visible = true) {
                      label2.visible = false;
                      label1.visible = true;
                      actionitem.title = "View Label 2"
                  }
              }
          }

  Hello

  My friend ther are different between '=' and '== '.

  You must write "is" (label1.visible = true) in your code to check the status.

• Hide the drop-down list when you print only when "PLEASE SELECT" is selected (unused field).

  Our form has several drop-down lists that by default the option "Choose", and not all of them are used whenever the form is used.  When we print a copy of each document, we would like the (unused) field "Choose" to disappear when printing - to make a copy of paper filter.  Is there a script for this?  I tried to use only the general framework ' Visible but does not print ", but of course, the field prints any - we need to print only when there was one another option as the default"Select"is selected.  Thanks in advance for your help.

  Coleen

  You can use a custom validation script, something like:

  Event.Target.Display = event.value = "choose"? display.noPrint: display.visible;

  To put this into effect, you will need to make a different choice and place it back to "choose." Another option would be to place as a custom Format script.
