I am interested in customizing the side menu. I would like to draw a shadow over the "previous screen" that had slid right when a hamburger / side menu opens.
Is there currently a way to accomplish this?
Here is a screenshot of what I would like to accomplish:
What would be nice if there was the equivalent of Dialog.setDefaultBlurBackgroundRadius(8); for SideMenu
You can do that pretty easily. Style the SideNavigationPanel UIID to white to create the background color, make sure it's opaque (bg transparency == 255).
You can add side commands with material icons using addMaterialCommandToSideMenu from the Toolbar class. However it will set the same color to both the icon and the text so an alternative would be to use an icon from FontImage or elsewhere.
The separator can be added like we do it in the new kitchen sink:
Label separator = new Label(" ");
Style separatorStyle = separator.getAllStyles();
separatorStyle.setBgImage(Image.createImage(40, 2, 0x7f000000));
separatorStyle.setBackgroundType(Style.BACKGROUND_IMAGE_TILE_HORIZONTAL_ALIGN_CENTER);
separatorStyle.setMargin(0, 0, 0, 0);
f.getToolbar().addComponentToSideMenu(separator);

I want to achieve this in Onsen UI:
Notice taller toolbar than standard, white overlay burger menu icon (for the standard element) and no bottom border between the image and the first item.
I think the burger icon is easy (assuming it stays in the right place with a taller toolbar).
The background image I tried manually setting the CSS property background-image in the browser DOM (using Chrome devtools) on the element and adding the transparent modifier, so <ons-toolbar modifier="transparent"> - unfortunately this got overridden so background image didn't show at all. I also tried doing the same thing on the within the toolbar and that didn't go full width and not sure the burger icon would have been on top anyway
Not sure how to override the toolbar CSS to make a tall/fat toolbar that shows the full height of the image and has no border - I've looked at the CSS for the toolbar in the browser DOM in Chrome Devtools but can't see how to modify it correctly
Ideally need this to be able to cope with different device widths or portrait/landscape orientation.
Any suggestions much appreciated. Thanks.
How do you change the UIID for the openIcon and closeIcon on a CodenameOne Accordion? It does not appear that there is any method available to do this.
What I am ultimately trying to do is to change the color of the material icon being used for the openIcon/closeIcon in one instance of an Accordion component. I have tried to do this a dozen different ways with no luck. I have been able to change the UIID of the accordion container itself, the header, and the content, but not the > icon.
I realize that I could create a > icon of the desired color and then use setCloseIcon/setOpenIcon to assign it. However, I would prefer to use the material icon, and those get their color from the UIID.
I see in the CN1 source that arrow.setUIID("AccordionArrow"); appears to be used in the AccordionContent class. However defining an AccordionArrow UIID in the theme builder does not appear to make a difference either.
You can customize the material icons programmatically. Create below method and reuse it where necessary.
public static FontImage materialIcon(char charCode, float size, int color) {
Font fnt = Font.createTrueTypeFont("native:MainLight", "native:MainLight").derive(CN.convertToPixels(size), Font.STYLE_PLAIN);
Style s = new Style(color, 0, fnt, (byte) 0);
FontImage fm = FontImage.createMaterial(charCode, s);
return fm;
}
//Change material icon, size and color as appropriate
accordion.setOpenIcon(materialIcon(FontImage.MATERIAL_ARROW_DROP_DOWN, 4, 0x4D5052));
accordion.setCloseIcon(materialIcon(FontImage.MATERIAL_ARROW_DROP_UP, 4, 0x4D5052));
In my app, I can't figure out how to properly style the toolbar with my logo image.
What I want to make it look like is pretty much like the Toolbar from the "Sport1" App.
Example
So I need the back Command on the left side of the toolbar, my logo in the middle from a MultiImage out of the resource and on the right another command.
Also, I'd like to let the Toolbar get smaller with scrolling.
What I have tried so far:
res_theme = r;
Form f = new Form(" ", new BoxLayout(BoxLayout.Y_AXIS));
logo = res_theme.getImage("Logo_Gema_vertikal.png");
f.getToolbar().getTitleComponent().setUIID("toolbar_image");
Style stitle = f.getToolbar().getStyle();
stitle.setBgTransparency(0);
stitle.setBgImage(logo);
stitle.setBackgroundType(Style.BACKGROUND_IMAGE_ALIGNED_CENTER);
stitle.setPaddingUnit(Style.UNIT_TYPE_DIPS, Style.UNIT_TYPE_DIPS, Style.UNIT_TYPE_DIPS, Style.UNIT_TYPE_DIPS);
stitle.setPaddingTop(5);
So, this looks good the way it is. I dont actually need a Title, thats why I do
Form f = (" ", ...);
If I don't add a title to the form, the toolbar gets very small and squeezes the background Image from the toolbar. The centered logo from the toolbar is just for styling reasons there, it does not need to have a command. Is there a way to leave out the Title? I now have set it to completely transparent, but for me this is just a work-around.
Also, I guess rather than setting the logo as background with a centered alignment, I think it would be better to add it to the title section as Image, but I don't know if this is better or how to do it.
Now, I also want to make the Toolbar get smaller when scrolling down. I found kind of a example code in the Codename One Toolbar Documentation, but it does not work out for me, since the background Image gets removed.
This was the code for the scrolling Animation:
ComponentAnimation title = f.getToolbar().getTitleComponent().createStyleAnimation("Title", 200);
f.getAnimationManager().onTitleScrollAnimation(title);
In the example, it worked. With my toolbar it does not, I have no clue why. I also can't see, where the size of the "after scrolling toolbar" is set.
Can I add there an Image as well? Kinda like one toolbar before scrolling with my logo, then while scrolling it transforms into a smaller one with only a textlogo image?
Here is my whole code what I have tried to make it work:
Form f = new Form(" ", new BoxLayout(BoxLayout.Y_AXIS));
logo = res_theme.getImage("Logo_Gema_vertikal.png");
f.getToolbar().getTitleComponent().setUIID("toolbar_image");
Style stitle = f.getToolbar().getStyle();
stitle.setBgTransparency(0);
stitle.setBgImage(logo);
stitle.setBackgroundType(Style.BACKGROUND_IMAGE_ALIGNED_CENTER);
stitle.setPaddingUnit(Style.UNIT_TYPE_DIPS, Style.UNIT_TYPE_DIPS, Style.UNIT_TYPE_DIPS, Style.UNIT_TYPE_DIPS);
stitle.setPaddingTop(5);
f.add(new SpanLabel("asdasdasdasd");
ComponentAnimation title = f.getToolbar().getTitleComponent().createStyleAnimation("Title", 200);
f.getAnimationManager().onTitleScrollAnimation(title);
f.show();
From the example above if looks like you just want to use the image as the title instead of styling the toolbar with a background image.
Just use ((Label)toolbar.getTitleComponent()).setIcon(myImage);.
I just started building my first App with Codename One and I'm having quite some trouble. :-)
I cant change the background color of a TextField, I changed everything in the Theme and named it "TextField". At the Color tab I changed the background color and set Transparency to 255. Since the Component is named TextField, shouldnt the style be applied automatically when I make a new TextField?
I also tried to set the UIID manually to "TextField", which didn't help either.
Am I missing something?
Kind regards,
Max
The way backgrounds work in Codename One is this:
Border is applied first
Then image
Then gradient
Then color
TextField and other components such as Button etc. often have a default border derived from the theme.
Switch to the Border tab, click derive then click the ... button and select empty.
How can i style the side menu, I created it using this tutorial youtube link, I want ot make it transparent and insert a label with a logo
please see below images on how i would like it to look like.
How it looks now

How i would like it to look when opened
To style the side menu, modify the SideNavigationPanel UIID in your theme.
To add the logo, you can do something like this
Toolbar t = new Toolbar();
form.setToolbar(t);
t.setTitle("tayary");
Label logoLabel = new Label(logoImage);
logoLabel.setTextPosition(Label.BOTTOM);
logoLabel.setText("label text here");
logoLabel.setUIID("SideMenuLogo");
t.addComponentToSideMenu(logoLabel);
Add the SideMenuLogo UIID to your theme, change Alignment to Center, and adjust the Top and Bottom margins.
To underline commands, modify the background in SideCommand UIID in your theme. It should be of Type: IMAGE_TILE_HORIZONTAL_ALIGN_BOTTOM. For the image, you can use any borderBottom image in your theme (If you don't have one, create any border using Image Border Wizard, and use its borderBottom image).
You can check this demo for a working a example.
