I have a written a custom toolbar. And I am having tough time to make it work (design wise). I have a couple of questions regarding it.
1)The main issue I am facing is to place the menu icons in their exact positions. When I tested it in different devices the gaps betn them is different.I have used table layout and grid layout for the menu icons as well & the logo in layered layout but the result is not good.
Code:
void addTitle(Form form, Resources theme) {
Toolbar toolbar = new Toolbar();
form.setToolbar(toolbar);
Container containerTitle = new Container(new BorderLayout());
Image titleImage = theme.getImage("toolbar_bg.jpg");
containerTitle.getAllStyles().setBgImage(titleImage);
containerTitle.getAllStyles().setBackgroundType(Style.BACKGROUND_IMAGE_TILE_HORIZONTAL);
containerTitle.setPreferredH(titleImage.getHeight());
ScaleImageButton ruslanLogo = new ScaleImageButton();
toolbar.setTitleComponent(LayeredLayout.encloseIn(containerTitle,
FlowLayout.encloseCenter(ruslanLogo)));
Image ruslanLogoImage = theme.getImage("ruslanLogo.png").scaledWidth(toolbar.getPreferredH() - 180);
ruslanLogo.setIcon(ruslanLogoImage);
Image emergencyImage = theme.getImage("emergency.png");
Image receipeImage = theme.getImage("receipe.png");
Image fmImage = theme.getImage("fm.png");
Image gameImage = theme.getImage("game.png");
TableLayout tableLayout = new TableLayout(1, 5);
//GridLayout gridLayout = new GridLayout(5);
Container tableContainer = new Container(tableLayout);
Button emergencyButton = getButton(emergencyImage);
emergencyButton.getAllStyles().setAlignment(Label.CENTER);
Button fmButton = getButton(fmImage);
fmButton.getAllStyles().setAlignment(Label.CENTER);
Button gameButton = getButton(gameImage);
gameButton.getAllStyles().setAlignment(Label.CENTER);
Button receipeButton = getButton(receipeImage);
receipeButton.getAllStyles().setAlignment(Label.CENTER);
Button transparentButton = getButton(receipeImage);
transparentButton.getAllStyles().setAlignment(Label.CENTER);
transparentButton.setVisible(false);
tableContainer.addComponent(tableLayout.createConstraint().widthPercentage(20), BoxLayout.encloseY(emergencyButton));
tableContainer.addComponent(tableLayout.createConstraint().widthPercentage(20), BoxLayout.encloseY(fmButton));
tableContainer.addComponent(tableLayout.createConstraint().widthPercentage(20), BoxLayout.encloseY(transparentButton));
tableContainer.addComponent(tableLayout.createConstraint().widthPercentage(20), BoxLayout.encloseY(gameButton));
tableContainer.addComponent(tableLayout.createConstraint().widthPercentage(20), BoxLayout.encloseY(receipeButton));
containerTitle.addComponent(BorderLayout.SOUTH, tableContainer);
toolbar.revalidate();
}
2)I have checked the width and preferred width, they differs. Does it affects the design?
int width = emergencyButton.getWidth(); //60
int preferredwidth = emergencyButton.getPreferredW(); //74
3)In above code, I used the bg image height to set the height of the toolbar. "containerTitle.setPreferredH(titleImage.getHeight());" Is it the good way to set height? Because the height changes slightly in android mobiles I have tested, however it looks horribly big in tabs, and I tested it in different simulator, the height differs greatly. How have you set the toolbar height in normal toolbar?
Image titleImage = theme.getImage("toolbar_bg.jpg");
containerTitle.getAllStyles().setBgImage(titleImage);
containerTitle.getAllStyles().setBackgroundType(Style.BACKGROUND_IMAGE_TILE_HORIZONTAL);
containerTitle.setPreferredH(titleImage.getHeight());
ScaleImageButton ruslanLogo = new ScaleImageButton();
toolbar.setTitleComponent(LayeredLayout.encloseIn(containerTitle,
FlowLayout.encloseCenter(ruslanLogo)));
4)How can I set the width of icon?
Image emergencyImage = theme.getImage("emergency.png");
Button emergencyButton = getButton(emergencyImage);
if I just do this, some devices the icon is too big.If I scale it eg: emergencyImage.scaledWidth(screenwidth/8) , the image quality is bad.If I set preferredW like emergencyButton.setPreferredW(100), the img width varies vastly in different devices. PS the images in the theme are saved as multiImage
Setting the preferred width/height is problematic as it implies the inverse dimension and might have quite a few implications. I noticed you used:
Image ruslanLogoImage = theme.getImage("ruslanLogo.png").scaledWidth(toolbar.getPreferredH() - 180);
Which sets the width based on the preferred height instead of the width/5 or something like that. It also sets the value based on preferred height before the toolbar construction is done so things will behave differently.
Preferred width includes padding which might affect your design. I would suggest creating a center aligned 0 padding/margin UIID in the designer and setting it to all of your components to eliminate padding/margin differences and shorten your code.

i want to add a background color to my container i tried everything but it's not working i didn't know why
Container c2 = new Container(BoxLayout.y());
for (int i = 0; i < lis.size(); i++) {
Container c1 = new Container(BoxLayout.y());
ImageViewer iv = new ImageViewer();
iv.setImage(Image.createImage("/" + lis.get(i).getImage()).scaledHeight(100).scaledWidth(100));
c1.add(iv);
c1.add(new Label(lis.get(i).getNom()));
c1.getUnselectedStyle().setBorder(Border.createLineBorder(5));
c1.getStyle().setBgColor(0xC40C0C);
c2.add(c1);
}
f.add(c2);
Border overrides background color which can impact the background. Also you will need to set the background transparency which in container is 0 e.g.:
c1.getUnselectedStyle().setBgTransparency(255);
I would suggest doing this in CSS or in the designer tool by defining a UIID to match your desired appearance then applying that using c1.setUIID("MyStyledBackground");.
You can have a border on top of the color by nesting containers.
How to keep the textComponent both float label and hint at the center of the screen horizontally. I've tried the alignment of the uiid like floatingHint, TextComponent, TextField etc to center in theme but nothing works.
TextModeLayout tl = new TextModeLayout(3, 1);
setLayout(tl);
TextComponent fname = new TextComponent().labelAndHint("Fname");
fname.focusAnimation(true);
fname.onTopMode(true);
fname.getAllStyles().setAlignment(Label.CENTER);
add(tl.createConstraint().widthPercentage(100).horizontalAlign(Label.CENTER), fname);
You would need to encapsulate the text mode layout in a layout that will center align. Notice width at 100% is the opposite of center align for the table. Also using the Style object would be problematic since we manipulate the UIID and erase your changes.
Specifically this should do that:
setLayout(new BorderLayout(BorderLayout.CENTER_BEHAVIOR_CENTER);
TextModeLayout tl = new TextModeLayout(3, 1);
Container myContainer = new Container(tl);
TextComponent fname = new TextComponent().labelAndHint("Fname");
fname.focusAnimation(true);
fname.onTopMode(true);
myContainer.add(tl.createConstraint().widthPercentage(100), fname);
add(CENTER, myContainer);
Still on my sidemenu from there, I've resolve the non broking text with a custom function that modify the text.
Now I'm stuck with the width of the component. I've change it from a SpanLabel to a TextArea in order to have more control on it's behaviour, but here is my problem: the TextArea width is too large as shown on the screenshot (put a ContentContainer UIID on to see the space occupied by the TextArea).
As you can see, the first component has a too large TextArea. I've set the column count of the TextArea to the length of the firstRow + 1, but it doesn't seem to take it in account.
The component is BorderLayout with a non grow center ScaleImageLabel and the TextArea on south. Is it a way to have a better width for the TextArea ? I would have it aligned with the image and with the area wrapped close to the text, but I really don't know how to achieve this...
Thanks in advance !
My suggestion is to use GridLayout for equal sizes or TableLayout with constraints for varying sizes for left and right components. It will prevent the TextArea from growing beyond a limit.
An example will be:
//GridLayout
Container cont = GridLayout.encloseIn(4, cmpL1, cmpR1, cmpL2, cmpR2)
//OR
//TableLayout with Constraint
TableLayout tl = new TableLayout(2, 2);
Container cont = new Container(tl);
cont.add(tl.createConstraint().widthPercentage(50), cmpL1);
cont.add(tl.createConstraint().widthPercentage(50), cmpR1);
cont.add(cmpL2);
cont.add(cmpR2);
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 am using following code to set gray light effect on window when I open a popup. It works fine but it basically reloads all controls or refreshes the main window .
Especially this line: currentWindow.Content = lightboxGrid;
Window currentWindow = Application.Current.Windows.Cast<Window>()
.SingleOrDefault(x => x.Name.Equals(MAIN_WINDOW_NAME));
Grid lightboxGrid = new Grid();
object currentWindowContent = currentWindow.Content;
currentWindow.Content = null;
lightboxGrid.Children.Add(new ContentControl()
{
Content = currentWindowContent
});
// now add the grid that will "black out" the content
Grid blackoutGrid = new Grid();
blackoutGrid.Background = new SolidColorBrush(Colors.Black);
lightboxGrid.Children.Add(blackoutGrid);
blackoutGrid.Opacity = 0.0; // start fully transparent
blackoutGrid.Loaded += blackoutGrid_Loaded;
currentWindow.Content = lightboxGrid;
this._lightboxEffectApplied = true;
What could be the option to have the same effect without refreshing the main window or reloading the controls?
If your main window has a Grid as its layout root (even if all the content is in the first cell), then you could add this blackoutGrid as a child to that grid and it will display above the other elements without messing with the original visual tree structure.
In this case, the Content of your Window would be a Grid, and you would add your blackoutGrid to that Grid, and remove it when you are done.
The way you are writing this seems to be a little against object-oriented practice. Technically it should be your Main Window that has the ability to display a lightbox effect.
