Is it possible to style a collapsed header in ExtJS so that it doesn't have a margin around it?
It seems it's all being positioned using javascript which means all my attempts to tweak it so far have been futile.
Any help will hopefully prevent me from ramming a full bag of heroin into my veins in order to forget that ExtJS exists for a few precious hours.
Use cmargins like you would margins.

I'd like to have scrollbars with no extension - that is no scrollbar is shown but a transparent scroll thumb which shows and hides automatically.
This may not be possible with Codename One, am I right?
You can override getSideGap to always return 0 and it should work. This is something we had as a demo way back in the LWUIT days.
I know it is possible to use grid's summary plugin and dock it to the bottom or top of the grid (underneath the header part), however I was wondering if it is possible and how would one go about putting the summary right above the grid headers..
Thanks.
Evan Trimboli gave the correct hint: You can adjust the weight of the summaryBar. This does not take immediate effect at runtime, so to enforce the new weight being used, you will have to call moveDocked:
panel.down('[itemId=summaryBar]').setWeight(99);
panel.moveDocked(panel.down('[itemId=summaryBar]'), 'top');

Is there a standardized way to create a multiline toolbar? I'm dinamically loading the items and they are usually more than enough to make the toolbar overflow. But I don't want the overflow functionality, I just want the items to span several lines. As the items are loaded dinamically, I can not create several stacked toolbars beforehand. An observation: I switched the layout from the implicit default 'hbox' to 'auto' and the items do span several lines, but then, features like separators have undesired collateral efects, like having only one item or separator on each line, and also different looks in different browsers.
I could dinamically calculate the suposed total width of the items and divide by the max desired width of a toolbar to obtain the number of toolbars I need, but I don't know exactly at what point the items get a valid useful width.
This is an old question posted by someone else sometime ago. I'm re-asking because perhaps with the latests releases of Ext JS, they shiped 'undocumentedly' the sooo needed layout solution for this issue.
Thanks!
I don't think there is an out of box component that can do all of the things you want.
The default toolbar layout of HBox just places everything horizontally spaced.
If you know that you need more space you can always put in a container with whatever layout you want for it's items. You can get creative and nest all kinds of layouts.
Personally I think this would end up looking ugly. Perhaps there is a better solution with an alternative approach to your design needs.
Alright, try as I might, I cannot for the life of me get rid of this tiny little border around my buttons.
Edit: I should mention, in case I didn't make it clear, these are buttons with an image on them, set to flat with the button sized to the image.
Images below:
Number one, I can't for the life of me get these borders to GO AWAY. I've checked everything I can think of. They're:
flat
border 0
no margins
no padding
manually sized to the size of the image (75px)
in a table layout where the columns are all:
manually sized to the width of the image (75px)
borderless
Nothing seems to really "work" to get rid of these. If I size the columns down to be 74px instead of 75px, most of them go away, but a few remain. I've triple and quadruple checked the images, and they don't have anything that I can pick up on that should be causing this... no transparency around the borders, definitely no border that looks like that.
Which leads me to the second problem:
Settings button when dialog is small...
Settings button when dialog is stretched out.
Settings button is also in the same table layout panel.
I've checked all the settings on the table layout panel as well.. I can't find any padding or margin or anything settings that suggest this should be happening.
Does anyone have any experience with this? What am I missing..?
Simple solution: using directly a PictureBox as if it was a button. You can change your image on mouse over or mouse click.
Have you tried a Toolbar/strip/whatever it's called these days? Probably not going to help as I believe it pads on your behalf, but worth a shot.
In the end you can toss the buttons in the trash and write your own control. A single control that manages N buttons will work well here.
I don't understand your second problem. What's the problem? It'll be fixed if you roll your own control anyhow.
While not a fix for the spacing issue, as a workaround you can make that gray gradient currently "behind" the "tabs" and control panel image into a BackgroundImage for the TableLayoutPanel using BackgroundImageLayout of Stretch. While not fixing the spacing issue, it would make it unnoticeable.
Writing a winforms control has its challenges (experience speaking here). I would agree that that is whats needed however. Depending on your project you may consider using XAML and WPF. It provides that fine detail you seem to be looking for in you application.
There are ways to host XAML controls in a winform app, but if you went this route it would be best to create a native WPF application. The reverse is also true (winform controls in a WPF app).
Did you check if the image has transparent pixels around the graphic pixels you want?
May be a simple crop solution.
I am developing a form in .NET Compact Framework, which hosts a variable number of controls. Every control should have the same width as the form. When there are only a few controls, no vertical scrollbar appears. When there are more controls than they can fit in one form, a vertical scrollbar appears. The width of the controls should then be modified, so that no horizontal scrollbar appears.
What is the best way to achieve this? I am interested in a solution that will work in all platforms/screen sizes and that can support screen orientation changes.
If I get this right, at one point, both a vertical and horizontal scrollbar appear, and you want only the vertical scrollbar? Doesn't setting the Anchor of each control to "Top|Left|Right" solve this problem automatically?
If every control is to be the same width as the form, why not just Dock every control to Top (or Bottom)? It'll take care of the resizing for you then. It might not look very attractive however, so I suggest adding in some empty Panels (docked the same way) to be used as vertical spacers.
I did some quick testing, and it seems, when you add controls, the panel raises the resize event when the added control tiggers the scollbars to go visible. The annoying part is here that the resize event is triggered a couple of times during startup :(
But knowing the compact framework, this might be your best shot at handling this.
Normally on the full framework you could if the DisplayRectangle is bigger than the size of the panel, but no such thing exists on the cf.
Hope this is of some help, I'll see if I can find anything more in the morning.
