The diagram below should help this be as clear as possible.
I have 3 panes A B and C. B and C are children of A, and B has children of it's own (white boxes). With drag and drop, I can move B's children anywhere inside B and be able to pick them up again, but if dragged over to C, or even the small part of A they can be dropped but can't be picked up again.
I use the basic controls. To drag I use imgView.setOnMouseDragged.
So how can I drag from one pane A, to pane B or C and still be allowed to pick up and drag the object again?
I had the same problem. This is how I implemented it with the help of Oracle forum member:
How to drag and drop tab nodes between tab panes

I need to implement drag and drop form in ExtJS 6.2 that adds components dynamically to a from.
I have a (grid)list on left side that contains type of components as texts, for example that list contains:
doctors (will be combobox)
units (will be combobox) "
check some constraints" in my case (will be checkbox) as texts.
I want to add that component (a combobox or checkbox) to right side of my panel when I click or drag one of them.
Each component can be added more than one. Can anyone show me the way or give me an example?
I come across to grid to grid or div drag and drop examples.
Thanks.
I have a splitpane created from FXML that consists of Three panes left to right. I want to be able to hide the rightmost pane but I can't find anything to hide it. If I turn of the visibility it hides the pane content. What I want is to temporarily hide it, so the pane is removed visually.
As a temporary workaround I move the divider to 100%, but this leaves the divider visible. Another side-effect is that if I resize the main window the divider doesn't stay at the rightmost position.
Any tips on hiding one pane in splitpane?
Or any tips on the best way to achieve this without splitpane(rightmost pane needs to be resizable when not hidden). General pointers to techniques/containers would be appreciated since I'm new to Java/JavaFX but not to programming :)
Seems I've found it, even thought it's not a plain hide/show deal. My splitpane is named "mainSplitPane", and the one I want to hide/show is the third. Upon initialization of the controller I retrieve the third pane and store it in "componentsPane".
Declared in controllerclass:
Node componentsPane;
Called in initialize method of the controllerclass:
componentsPane=mainSplitPane.getItems().get(2);
Code to hide:
mainSplitPane.getItems().remove(componentsPane);
And code to show:
mainSplitPane.getItems().add(2, componentsPane);
mainSplitPane.setDividerPosition(1, 0.8);
A side effect is that I have to set dividerposition since it's removed.
I'm new to Delphi. I really wanted to build a Preferences Windows in my company legacy system (which uses 'Delphi 2010' today) just like Eclipse's.
I could already mimic almost all the items:
Divided the whole screen in 3 panels (one at the left, one at the right and one at the bottom),
On TTreeView inside the left panel, and one TScrollBox on the panel of the right to be able to scroll things if they don't fit on the window for any reason (low monitor resolution or too much options). Even used a TSplitter between panel on the right and the panel on the left.
Here's what I could get:
My doubt is: what should I do to be able to load multiple options once an item inside the TreeView is selected? What delphi component should I use to mimic all this info in the right panel?
Make a frame for each page. This is kind of a "sub-form" that you can design visually. Create and destroy them at runtime in the appropriate event-handlers of the tree view.
Use a TPageControl. Add a TTabSheet for each group of controls you plan to have — one for each item in the tree control. Set TabVisible := False for each sheet to keep the tabs from appearing at the top of the page control. Each time an item in the tree control is selected, make the corresponding tab sheet visible by setting the page control's ActivePage property. Put controls on the sheets according to the preferences associated with that sheet's category.
In IB I have quite a few views that are shown. Many of them are hidden when the app loads, but are shown later when buttons are pressed. This is all fine, but when building this layout in IB it is extremely difficult to layout anything because there are so many overlapping views, some of which are partially transparent (ones that are set to hidden) and other are completely overlapping and covering others. This makes layout very hard.
What is the best method when laying out lots of views like this? Is there another way to break things up? Or better yet, can I hide a a view completely (like in photoshop) so that I can edit the ones underneath, then turn that layer back on?
Another option when trying to select a view that is obscured by another is the shortcut:
'ctrl' + 'shift' and click
It displays a list of all the views under the cursor.
I'm not aware of any way to hide objects in the canvas, but a useful trick for complex layouts is to double-click an item in the document tree to the left - this selects the item and puts focus on the canvas, you can the use the cursor keys to nudge it about.
This doesnt solve the problem of not being able to see things because there are, for example, five or six labels occupying the same space, but if that is the situation it may be a better idea to have a single label and change its contents in code.
I ran into this issue for an app I'm building that has an arial-view image of a park with clickable hotspots. When a hotspot is clicked a popup UIview is displayed with information about that spot in the park. I use the same VC/XIB for three parks. This makes the XIB really busy and hard to work with (i.e the same issue that you have) The detail UIViews make it hard to work with the views underneath. My workaround was to pick each detailed UIView that was hiding the part of the XIB I wanted to work on, and add 1000 to the UIView origin.x in the size inspector. This moved those UIViews enough out of the way for me to do what I needed to with the XIB. Then when I was done, I moved them back by x 1000. (I just needed to move them out horizontally to do what I needed to)
I know its clunky but given that XCode does not have a convenient way to hide portions of an XIB - it was the quickest approach I could think of!
One approach to handling overlapping items in IB is:
Ensure the groups of items that you want to hide are grouped into Views.
Give these Views names: e.g. ViewOptionA, ViewOptionB and ViewOptionC.
Can do this by clicking on name of view in the tree while it is selected and then typing new name.
When you want to hide one of those groups of items:
a) Select the View by either:
i) Clicking on it in the tree at the left or
ii) Ctrl-Shift Clicking in the layout editor and then select the view from the list.
b) In the Attributes Inspector set Alpha to 0.
When you want to unhide one of those groups of items:
As for 2) but set Alpha back to 1
[You do need to remember to unhide all views before you publish!
If you are forgetful like me then perhaps you could subclass UIView and set Alpha to 1. I haven't tried this subclassing idea yet.]
Thanks in advance.
I am creating one GUI on new wizard, that is available in eclipse by default, in wizard page i m creating GUI in createControl method , now for that i am creating one composite that is child of parent in that i have to create two composite from left to right in which left one should only expand horizantally and right one should expand in both directions horizantally and vertically
Now in left composite i have to display images located in c drive location and when user clicks on images displayed in left composite , in right composite specific images will load .
Now functionality i have completed using rcp , used fill layout for both composite and scrolled composite and row layout for inner composites that displays images with label , now the same logic i am implementing in wizard page but GUI is nonexpandable ......it sucks.......i tried every layout but i don't know where i m lagging ....as i m newbee in GUI ...:(
My problem is how to display two composite in wizard page , where first is only vertically expandable , and other one is expandable in both directions, and display images in these composites , that are located in my c drive ........
The parent composite layout shoud be grid layout. For the left child composite, set it layoutdata to be vertical expand. As for the right composite, set it to fill both.
Hope this help.
