How to add vertical gripper for each TableRow in a TableView?

I am looking for a better approach / best practices to accomplish this task. I need to be able to implement, for the less resizable (sliding on a dividing line) TableRow. I understand that this is a little more difficult to maintain the height of each individual TableRow because they are virtual and reused. My first goal is to have all TableRow resized (eliminating the need for individual line sizes).

I am able to set up my own TableRow expanding TableRow - and I managed to retrieve a reference to the skin of the TableRow and adding a line of separation (Rectangle) and capture mouse events to effectively resize the row height by dragging.

My Question is this: without implementing a new TableRowSkin - how can I force the line of separation at the bottom of the TableRow? Currently - I just added the node Rectangle (divider) to the list of children of the TableRowSkin - causing the dividing line be positioned on top of TableRow (which gives a vibe when resizing - the line should be on the bottom).

I feel I'm hacking at the question without being aware of the intention of the JavaFX developers. The intention of the row height resizes to be implemented by providing a new skin? It doesn't seem to be an easy way to accomplish this task using the existing TableRow or TableRowSkin.

I can post the code if requested example - but I'll need to condense the example of a small enough standalone file.

If the answer is Yes - "put in place a new skin" that's fine, but this task can be difficult without the source code of advice :) [Tip... Tip..]

Hi jkaufmann,

If you want to add the vertical panel resizable on every row then you need to implement the cellFactory() for each cell in columns.

There are a few steps that makes this possible:

D ' apply the cellFactory for all columns. You can addListener for the ObservableList of TableView.getColumns ().
-Add resizable Panel either rectangle or someone you like then check setCursor (Cursor.V_RESIZE) for this Panel. To make the rectangle/node always thoroughly and then use BorderPane layout
-Now add a few events on Rectangle/node
-create two variables: start, end
-setMouseClicked (help to set the starting value: position of y)
-setMouseDragged (change the cell height according to the change in y ie. end-start.) And also update the end value according to the current position of y)
-setMouseReleased (Finally, reset to 0 for the start and end value)

-Now add a few lines and test them. It works smoothly

Hope this will give you some tips

Thank you.
Narayan

  • How to add notes (stars) for comment in the layout of the Webapps list?

    How to add notes (stars) for comment in the layout of the Webapps list?

    Then... I've found a workaround. It's dirty and messy, and I don't know there's a better way, BUT using an Iframe in your list template that refers to your details page you CAN get the sides to work in list view.

    Here's what you do:

    1. place a comment form and the scoring module in your model detail page.

    2. place iframe in the list of your webapp template and point src = "detail_page_url".

    3. get this plugin to find the location of your scoring module in your details page: Page control - Chrome Web Store

    4. set the iframe scroll position so that when you view the list of your webapps it automatically queued upward at the position of the note on your details page module. Style the iframe using the attributes listed here: Scroll the IFRAME in a preset Position content

    So essentially of workaround reflects everything that happens in your detail page. Do not know if I explained that very well so if you need a clarification let me know.

  • multiple choice with partial credit question, I have 10 responses only 6 are correct.  How to assign 10 points for each of the six correct answers for a total of 60 points setting?

    How can I assign partial credit so that for each possible answer 6 out of 10 each correct answer gets 10 points each, with a possible total score of 60 points quiz?

    To Captivate 7, please go to the Quizzing workspace. You will have the properties and properties Quiz Panel visible. I will now repeat the workflow, I explained briefly for CP7:

    • Check the partial score in the Quiz properties and also multiple responses.
    • Indicate the correct answers on the stage
    • Select the first correct answer on the stage text caption and indicate its score (10pts) in the properties panel, not in the Quiz properties!
    • Repeat the same for each correct answer
    • Check the total score in the properties of the Quiz Panel: should now be 60pts to the full question.

    None of the quiz system variables can be changed, they are read-only. System variables in Captivate 6 - Captivate blog explains the system variables for 6 categories, there are a few changes in 7: new features of Captivate 7.01 - Captivate blog but the Quiz category is always read-only.

  • How many profiles is there for each camera?

    When I develop my Nikon D700 raw files, I have the choice of a number of profiles such as Adobe Standard, camera Vivid, Portrait of camera neutral camera and different modes of DX2.

    However, with the raw files from my Olympus E - P1, I see only one profile; - Adobe Standard.

    None of the E - P1 as Vivid modes, silent, natural or Monotone seem to be emulated by Adobe.

    Is that correct and how do I know which profiles Adobe has actually produced for each camera?

    Ian

    Is that correct and how do I know which profiles Adobe has actually produced for each camera?

    Yes, not all cameras have camera-specific profiles. For the most part it is Canon and Nikon and a few others. Take a look at yto our camera raw profiles directory, you will see all of the profiles here. On Vista, you can find it here C:\ProgramData\Adobe\CameraRaw\CameraProfiles\Camera.

  • How to measure the time for each mapping?

    I use oracle11g with OWB.

    I have several mapping and each dimension tables to update the mapping.

    I want to measure how long it takes to complete each mapping. What is the best way to find the total time for each mapping.

    One way is, we can have POST MAPPING and PROCESS of MAPPING PRE. I can trigger the stored procedure to enter the start time and the end time of each match. On this basis, I can calculate the total time for each mapping. But I have 50 mapping. Now, I need to write 50 different stored procedure and open the POST-PROCESSING of the MAPPING and PROCESS OF MAPPING of the PRE for each mapping. It is complex.

    Is there another way, we enter the total for each mapping of execution? Y at - it that no data in OWF_ MGR dictionary can help on this?

    I would be grateful if someone can help me on this.

    He will remain forever unless you purge it explicitly.

    Hi cm,

    This looks like a work of fusion and mailing.

    The merge document would create in Pages, and the cells of merger on this document référenceriez cells in the table in the document numbers.

    See the documentation Pages (on the Help menu) for instructions on the conduct of merger and mailing.

    To do this in only numbers, you would need to put in place a 'table of declaration' on a separate sheet (in the same document as the table containing information) which would accept a customer number (or other key ID for each individual) then use it to determine the line of the main table to retrieve information about this pattern.

    A more precise answer requires a more specific desription of your table structure and the desired form of the instruction to take.

    Kind regards

  • How to configure applications private for each user?

    I created different users in a single workspace. I want that applications of each user to be private so that user applications should not be regarded by others.
    Can someone suggest me...

    Thus, the term "user" was used in "application developer".

    The idea behind Apex Application Builder is the team and that's why you have offers to work as a team. You want to go in the opposite direction for your reasons.

    The only way I know is to create the workspace separately for each developer. In this way, that each developer sees only its applications in Application Builder. If developers use the same tables/views of db, then you must assign the schema that contains the data for each of these workspaces.

    But if you want to ensure that developers do not yet see each and other data and then they you need to keep the data as separate.

    While it's all just do not forget that some days, that applications must be deployed and end users must Access!

    I'm not aware of any other mechanism to isolate developers.
