hello,

i'm trying to develop a rcp application. in that application i've got a 'navigation' view on the left side while the most space is on the right side, the editor area.

in the navigation view i'm working with a form. in that form i would like to put three "rows" of different widgets.

1. a section with elements to define filter data.
2. a textField to input a search string.
3. a table listing all the entities available for editing.

i got row 1 and 2 working but i'm having problems with row 3. also the table is shown it does not look and behave the way i want it to do. i would like to have it:

1. exactlly be as high as the space left (minus the two upper rows) in the form's parent view including refreshing/redrawing when the size changes due to window resizing by the user.
2. be as width as the view is including resizing when the user makes the view wider or smaller.
3. show a vertical scrollbar in the table widget if there are more items in the table than can be shown currently.
4. show a horizontal scrollbar in the table if the text of one or more items is longer than the table's parent view's widht. or even better, cut the text followed by three dots or somthing like that.
5. draw the table that way that the whole line is selected when an item gets selected, not only the item it self.

up to now i got it to be shown but it is only as width as it needs in order to show the items and if i put an item into it whose text is longer than the view containing the formTable, the table is wider and the parent view shows a horizontal scrollbar. if i then add an item programmatically, the table starts showing a vertical scrollbar.

Hi Dirk,

Did you manage to get it working? What exactly is your question?

hi wim,

no, unfortunately not.i already thought that no one will understand my description... Wink i give it another try.

i'm developing a rcp application. in that application i use a common layout where about 20% of the window on the left side is used for navigating through a list of entities hence called the navView, let's say person objects. the rest of the window is reserved for the editor space.

if i place an ordinary table in the navView i got it managed to have it behave in the way that the table fills all the available space of the view it is placed in, the parent. if i resize the view, the table gets resized, too. if the view is not wide enough to show the whole lines in the table, the table rows' text get cut with three dots at the end. vertically the table does not exceed the available visible area of the view and a scroll bar is being shown thus i can scroll through the list. all in all exactly as i want it to behave.

i then added a further view on the left side. this time i placed a form in the view as i want to have three "parts" to be shown stacked vertically. at the top a section which contains controls to define filters for the list of persons. below that section a line with a textField and a button to enter search strings. the rest of the visible area i would like to fill with a table that behaves the same way as the table i placed directly into the other view. but what ever i do, what ever layout i use i do not get it behave the way the other table does. the table always flows over the visible area in the background horizontally and vertically. furthermore the table does not show a scrollbar until i add another row programmatically. the only thing that gets a scrollbar is the form if i use a ScrolledFrom. but if i use a scrolled form the whole content of the parent view gets scrolled, not just the table content.

i hope i explained it a bit more comprehensible this time... Wink

any idea on how to get this problem solved?

thx a lot,
gree,

dirk

Hi Dirk,

I see what you mean. The table dows not wrap correctly...

This has to do with the layout manager, which can be tricky to figure out if
you do it by code only. Especially if you are inexperienced with this kind of
stuff (which I assume you are, but correct me if I am wrong).

Try to install the former Instantiations tools (Window Builder Pro). They are
now free since google purchased them. This enables you ty wysiwyg design your
form and execute the layout managers at design time. This should help you
solve your problems. If it does not, come back and post your source.

Hi,

Yes, my all time favourite is GridLayout. I hardly use anything else.

It basically lays out the parent in columns.
children can "grab" excess horizontal and vertical space
children can cover more than 1 column

Hey Dirk,

I had the EXACT same problem with the exact same type of view.

I am guessing/hoping you are using the GridLayout for your filter area. In this case make sure that the composite grabs the horizantal and vertical space. Also, and this is the key part, make sure that the align is set to (SWT.FILL and SWT.CENTER)

For the table composite make sure that the table is wrapped in a Composite with a GridLayoutData object that grabs space horizontally and vertically.

The layout of this composite should be the TableColumnLayout.

I HIGHLY recommend looking at this example here and actually using his library that contains the TableViewerBuilder.

I am using that now and its a huge help!

hi all,

meanwhile i managed to get it working as i want it to do. thank you very much, wim. the tool you suggessted is great. i think i will not create views in any other way anymore for a long time... Wink

for those who are interested: in set a FillLayout in the parent composite passed to the public void createPartControl(Composite parent) method. i then added a composite to that parent having a GridLayout set which is the container for all the "viewParts". i added one composite to that "containerComposite" which is the parent of the table and i set a TableColumnLayout for that composite.

by doing it that way, things are working now.

thank you all very much for your help!

greez,

dirk
