Change the contents of cell based selector QML property in container QML

I have a selector in which I want to have the text in each cell selector display in one of two ways, depending on the State of another control in the QML that surrounds the selector and the other controls.

My first attempt used only a QML based Picker with PickerItemComponents.  The PickerItemComponents had their text property set to the return value of a utility JS function that takes two arguments - the PickerItemData extracted string and an indicator a boolean to indicate the JS function how to change the string returned to display in the cell of the selector.

When I try to spend a QML property set on the selector for JS calls in the PickerItemComponents, I get an error log saying:

"" ReferenceError: can't find variable: ".

I assume here that a PickerItemComponent is missing the context of the selector containing the same way that a ListItemComponent is not the context of the parent company of the ListView.  However the docs of PickerItemComponent do not seem to set all of the properties that I could use similiarly to the ListItem.view property, which is ListItemComponent.  (In fact, the PickerItemComponent docs don't same spec property of pickerItemData - it only appears in example code).

So the next thing I plan extends the C++ PickerProvider class.  However, it seems that this class inherits QObject, not so I don't know if once I go to the trouble to write and expose my own version, I'll be able to finally get the QML of the container including down in the correct callback inside my custom PickerProvider.

Anyone who has been in this way, please share your experience/solution you are able - thanks!

  • Change the color of cell based on the text in another cell.

    Hey everybody, hoping that I can get some advice. I searched autour and finds only advice exceeded on a previous version of a number.

    I use 3 numbers

    Very simple question, in the hope of a simple answer

    Above is what I want the result to be.

    The "Number" column is a pop-up menu with a list of different text. I wish that the color of cell status change depending on which element is selected.

    I looked in the conditional highlighting, but it doesn't seem to be what I'm after. I would be able to get this working with formulas or a mixture of both?

    Thanks in advance for your help.

    Hi .adams,

    I do not understand the cells that you compare to get a color. It is a cell in the left column or a cell in the right column?

    Please tell us your overall goal: 'what' you want to do, rather than "how" to achieve this.

    More information, will lead to a solution.

    Kind regards

  • Change the color of cell based on the first character of the value of the field

    Inside of a RTF model, I have a field called I_DESCRIPTION.

    If the first character of the value of I_DESCRIPTION is 'E' then I want the table cell to be red. Otherwise, I want it to be blue.

    I thought I'd be able to use the following type of code:
    <?xdoxslt:ifelse(substring(I_DESCRIPTION,1,1)='E', 'IT IS E', 'Not E')?>
    The above works. The only problem is, I don't know how to change the above, so that instead of print 'IT IS E' or 'NOT E' it changes the color of the cell in the table in red or blue.

    I guess I have to put something like the following in the second and the third argument to the ifelse() function:
    <?attribute@incontext:background-color;'#FF0000'?>
    But after much trying, I can't work on everything at is how this fits.

    Ideas or suggestions appreciated.

    Thank you
    Andy

    Hi Andy,.

    You can try this:

    1. in the cell where you view the description field, insert a form of conditional formatting field and use the following code: Red

    You will need to check the condition of other another field of form CF: Blue

    Hope this helps.
    Thank you!

  • change the color of cell

    I'm interviewing an Access db and displays the result in a dynamic array. one of my columns db is priority (high, medium, low) calls

    is it possible to change the color of cell to say red based on the result of the query. so I do the cell red if the priority was "high"?

    It is safe. exact syntax will depend on what type of data of your "priority".
    column (text? number?)

    something like this should do the trick:

    ....

    'high' > style = "background-color: # 990000" > #myquery.prioritycolumn #.

    (if your column 'priority' is numeric, simply replace 'high' on the inside of the)
    Statement by CFIF with sufficient number)

  • I need to create a table of contents in iPages but I want only one word for the title, not the line of holes. Or, how can I change the contents of the table? Thank you!

    I need to create a table of contents in iPages but I want only one word for the title, not the line of holes. Or, how can I change the contents of the table? Thank you!

    Yes, you can have a one word title, by assigning a paragraph style title to this one word. No, you cannot change the text in a Table of contents, but you can change paragraph style font attributes (line) and add for example, a head of points between the types of OCD paragraph and page numbers. No part of the table of contents will not provide hyperlinks in exported PDF documents.

    When you look up in the menu bar, you can see the word iPages, or simply Pages. There is no product of iPages.

  • Change the contents of the message body and keep the attachments using a FolderListener

    Hello

    I need to change the content of specific e-mails when they are received on the device. I use a FolderListener to detect when the message arrives, and I'm able to edit the content of the message. The problem is, attachments are lost in the process, but I need to keep. I just want to change the body of the message.

    Here is my code:

    public void messagesAdded(FolderEvent e) {
    
      Message m = e.getMessage();
      Object content = m.getContent();
    
      if (content instanceof Multipart) {

  • Change the amount of cells in the grid - Lightroom CC Mode library view

    Hello! I'm changing the amount of cells in the library Mode/grid. Right now my only option is to have either a display of photos or having eight photos through horizontally by pressing the command button less. When I press command more dates back to only a photo. Previously (months), I was able to see the photos of 3-4 through horizontally. How is it possible to vary the report/amount of photos in the intermediate space? 1 to 4 to 6, etc.? Thank you for your help.

    Press simply the = and - keys, without adding command. These only keys will change the size of thumbnails for you; they are shortcuts for view > increase the size of the grid and view > decrease the size of the grid.

    When you press command +, you zoom in the view of the magnifying glass and then exit the display of the grid. Which is why you don't need to add command, if all what you want to do is change the size of the grid.

    Matthew

    Hello

    On luck outside, that you are not really wanting to address the 'skin in a CHM' quite yet, try this.

    First, note the path and the name of the file that you want to appear when the user clicks on the Home link.

    Open the pod of setting up a project. (View > pods > project configuration)

    Expand Windows, and then double-click the CHM window. (If you do not see a CHM window, you will need to create a)

    In the Properties window, click the Advanced Properties button.

    And from the Advanced Properties dialog box, you type (Yes, you heard that right, TYPE) the path and the name of the file you want. (Remember this first step?) Note that you can also type a URL pointing to a website here.

    Hope this helps... Rick

  • Why can't I change the content at different breakpoints?

    For some reason, after the establishment of breakpoints on my master, whenever I try to change the content at different points of rupture on my subsequent pages, if I click on a breakpoint I can get to this provision of breakpoint, but the cursor turns into a pen and a circle with a line through it and says 'Click here to directly access the breakpoint'.  If I click once again, I need to come back on the breakpoint (1200px) original on as I was.  Can someone tell me why I can't edit content on other breakpoints?

    You cannot change the content between breakpoints.

    If you want a breakpoint of master page to be accessible on a layout page (which is not make sense in many cases), click the small arrows, who are appearing in the breakpoint bar, which represents your breakpoints in the master page, and then click the 'create a new breakpoint' that appear :

  • change the settings of export based on photo

    Hi all, I searched a lot, without finding an answer to this task: I need to change the settings of export based on unique photo, for example settings megapixels resize factor rating function.

    I know that export settings can be changed with updateExportSettings but it is global for all photos of.

    I also know that in the Export Department, I can define a processRenderedPhotos function in the loop inside the session: "renditions", I can do additional actions on each photo, but after having been made.

    I know finally I can define a filter Service where to put the postProcessRenderedPhotos function, but it is a post-processing work so after the photo was made and registered...

    Then... How do I? Where to put code to change exportSettings for each photo based on a feature of the photo?
    Thanks a lot for your help

    Julian

    How to access every photo in the function "filterSettings = function (renditionToSatisfy, exportSettings)"...? As I said, I need customization of the exportSettings based on characteristics of the photo, so I need to access the photo associated with a current rendering: how?

    The 'renditionToSatisfy' argument is class LrExportRendition, and renditionToSatisfy.photo gives the restored LrPhoto.
