I'm using iGrid.NET.
If the columns are bigger than the available space, a scrollbar is shown:
Now when I click on a column which is partly outside the visible area, the clicked column is shown at the left start:
I know it's unusual, but I would like the scrollbar to stay exactely where it is.
I want to have col 1 shown on the left.
How could I do this?

I have 2 buttons. say for example a "Browse" button and a "Start Data Backup" Button. I have applied a common style to these buttons. find the buttons below.
As you can see, the content of the browse button aligned properly to the center. But the another one doesn't have any borders. it occupied the button completely. I know it is due to the length of the text and we can fix it by setting the width of the button, but unfortunately i cannot set my button width .because i need my button should give same look with different screen resolution.
What i need now is, the content should be aligned as like in browse button regardless of content length. How to achieve this?
If you have limitation on changing the width of Button for different screen resolutions, instead of changing the width of button try overwriting the font size of the content in button. Also make use of content wrapping to get extra text in new line.
Referring to this question and answer by Shai Almog:
Rebuild list of containers without scrolling the list
I have a form with one container (TableLayout), which contains several rows with labels and buttons. Clicking a button changes the order of the rows and rebuilds the whole form (after myForm.removeAll() ). After myForm.revalidate() the form jumps to the top.
I am trying to implement this exact behaviour, to return to the same point (scroll position Y) after revalidating/changing the container contents.
I subclassed the Container-class to make setScrollY(int) visible. Using this with an arbitrary value does not scroll to the position, so it seems that the setScrollY method is not changing the scroll position of the content pane overall.
And myContainer.getScrollY() always returns "0". I only get the scroll position by calling getContentPane().getScrollY().
But it is obviously not possible to call the setScrollY()-method on the content pane - as it is not possible to subclass the content pane - to scroll back to the same position after revalidating the form.
Thanks for any advice!
Use border layout which disables the scrolling of the form/content pane.
Place your container (where you exposed setScroll) in the center and make sure to invoke setScrollableY(true) on that Container.
When I press a button, my app displays a calendar (within a Dialog) that slides from the bottom of the screen:
I want the Calendar to occupy the whole width of the screen, but it shows some white padding on both sides and also on the top and bottom (It is white because the "Dialog" UIID has a white created image as background)
I have tried changing all the UIID related to Dialog: "Dialog", "DialogBody", "DialogTitle", etc. I set all margins and paddings to cero.
How can I get rid of that padding?
Try change both the DialogUIID and the UIID of the dialog. Also make sure your calendars margin values are set to zero. It could be that your calendar is too small. Try placing it in a table layout with 1 row and 1 column then in layout constraints set the width and height to 100%
Open up the Component Inspector tool and traverse the hierarchy. You will be able to see all the components and their UIID's within the hierarchy and you should be able to understand which one of those components contributes to the padding/margin.
Please, see picture bolow:
I cannot get rid of white paddings/margins in combobox popup. I have two custom containers in designer called DropdownItem and DropdownItemSelected, Fisheye renderer type for ComboBox renderer. As you may see in combobox selected item is displayed just fine. However, in I cannot get combobox popup displayed without white paddings. I have actually used PopupContentPane to add blue border around popup, I also have border set to empty, all margins/paddings set to 0 for following UIIDs: PopupItem, PopupFocus, DropdownItem and DropdownItemSelected. PopupContentPane has also all paddings/margins set to 0. Also see my contants:
I went through source code and cannot find any other useful UIID I can style in order to remove these white paddings. Can someone help me with this?
Update:
Might be helpful - see below how popup looks like when PopupContentPane border sickness is set to 2px:
Update 2:
Almost there. After setting listItemGapInt constant to 0 I managed to remove gaps between list items. See screenshot below.
I still cannot find out how to remove 2 pixel gap on the right and don't know where it's coming from. Would appreciate any thoughts/ideas.
Update 3:
I eventually found where two pixels are coming from.
com.codename1.ui.ComboBox class, lines 289-290
289 int listW = Math.max(getWidth() , l.getPreferredW());
290 listW = Math.min(listW + getUIManager().getLookAndFeel().getVerticalScrollWidth(),
parentForm.getContentPane().getWidth());
In my particular case, listW=630px and in line 290 listW is recalculated as Math.min(630 + 2, 768), where 2px is width of vertical scroll.
As far as can say, scroll bar should be a part ComboBox popup.
I managed to remove unwanted gaps. As I mentioned in 'update 2', listItemGapInt should be set to 0 in order to remove horizontal gaps.
Vertical gap was related to scroll bar however it was not clear that it's a vertical scroll bar that creates that gap. After I set paddings to 0 for Scroll UIID, vertical gap has gone.
In regard to update 3, this is a bug but not because it should be in the container. The list is scrollable so this should be a part of the list however the call should be to l.getSideGap() and not to getVerticalScrollWidth().
This will allow you to hide that by setting the scroll bars to visible false etc. We'll fix that for the next update.
I have a winform app. On the menu bar, far right, I placed a dropdown box on top of it. When I resize the form the dropdown box obviously stays in the same position (x,y location). How can I get it to move propotionally to the right when the form is resized. It basically stays on the same Y axis.
I can't use a layout control since it's placed on top of the menu.
You can use the Anchor property of the comboBox to do this. Simply set it to Right (probably Top and Right) through the designer.
Or to do it in code:
comboBox1.Anchor = AnchorStyles.Right;
