I'm trying to add a Grid into a VerticalLayoutContainer of fixed size (250 px) and have the user be able to scroll vertically.
I'm using the following code, however, the grid does not display at all.
VerticalLayoutContainer vPanel = new VerticalLayoutContainer();
vPanel.setHeight("250px");
vPanel.add(grid, new VerticalLayoutData(1, 1));
grid.setHeight("auto");
add(vPanel);
The Grid displays in other circumstances, but covers up other GUI elements (no scrollbar).
Hopefully this is an easy fix for those more experienced with Sencha GXT.
Thanks to anyone taking the time to help me out...
try this:
vPanel.getScrollSupport().setScrollMode(ScrollMode.auto);
If it doesn't work, then, try this:
`
ContentPanel p = new ContentPanel();
p.setHeaderVisable(false);
p.setBodyBorder(false);
p.setBorder(false);
p.setHeigh(250);
vPanel.add(p);
p.add(grid);
`
then grid, will automaticaly have scroll mode.
I had the same problem with a Grid in a ContentPanel, that is, the grid didn't show a vertical scrollbar. I used ContentPanel#forceLayout immediately after adding the grid to the panel, and it resolved the problem. Here's the actual code:
Grid<Pet> grid = new Grid<>(listStore, columnModel);
grid.setBorders(true);
grid.setColumnReordering(true);
grid.setLoadMask(true);
grid.setSelectionModel(selectionModel);
grid.setView(createGridView());
ContentPanel contentPanel = new ContentPanel();
contentPanel.setHeaderVisible(false);
contentPanel.add(grid);
contentPanel.forceLayout(); // <---- this is the line that fixed the problem!

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'm not sure if this is the right place to ask because I dont have any code to show. I'm actually looking for ideas on possible ways to solve my problem.
I have an app that displays the grid on the screen when the media query has a min width of a tablet.
But when the view is in mobile mode I don't want to show the grid. Instead I have a drop down menu which has a grid option. When selected will be show in a paper-dialog (pop up)
The problem is I have to create two grids (vaadin-grid) and show the appropriate one based on the view. Is there a way to have only one grid? Can I put it in a paper-dialog but not pop-out when in tablet and desktop view?
Thanks in advance
If your grid element has every custom property then that is an element in the DOM, so you can move it into the dialog if thats needed using javascript:
let myGrid = this.$$('#myGrid');
let myDialogContent = this.$$('#myDialogContent');
Polymer.dom(myDialogContent).appendChild(myGrid);
Also if you think it a different way, then you can hide the grid outside of the screen and you can slide that in when it's needed like a drawer panel and you dont need to move the element at all in the DOM.
By the way for programming question stackoverflow has the https://softwareengineering.stackexchange.com/ site, but I think it is Ok to send it here.
I am using ng-grid when I drag the window the grid resize well. But when I click a button to make the window bigger,the grid does not resize.
UPDATE: Actually, the grid is resized. However, the row and column are not.
I notice in 3.x they have autoresize function. Unfortunately, I cannot update to 3.x version. Is there any way I can fix it?
$scope.gridOptions.$gridServices.DomUtilityService.RebuildGrid(
$scope.gridOptions.$gridScope,
$scope.gridOptions.ngGrid
);
I used this code the rebuild the grid and it solve my problem.
Thanks for everyone's replay.
When Data loads in grid and scrolling appears, I can navigate it through up/down arror key. But when the pointer goes down not able to see the content in grid, i mean the grid does not shift upword automatically.
Looks like your grid is not rendered properly. Judging by your description your grid is bigger then the panel it belongs to. Please post some code and screenshots.
I am using sencha to update a panel as follows.
I will have a handler for a button.
In that i am removing a docked panel from a panel. and then adding the some new panel as a docked item.
But the contents of the panel are not appearing. They are appearing only when i change the size of the browser window, i.e., maximize it or restore it.
How can the problem be solved?
The code for the problem is as shown below.
handler: function(){
chaptersPanel.removeDocked(chaptersList[chaptersPanel.getStory()]);
chaptersPanel.insertDocked(0,chaptersList[this.no]);
chaptersPanel.setStory(this.no);
chaptersPanel.doLayout();
mainPanel.setActiveItem("chaptersPanel");
}
YOu need to do a doComponentLayout() sometimes. Sencha Touch is a little flakey about it. doLayout is supposed to handle the componentlayout, but it doesn't always
