I am using monotouch dialog to generate a view. I managed to change the background color by subclassing DialogViewController, but the contrast with the section caption makes the text hard to read. How do I change the section caption color?
I am also using a StyledStringElement as a button in the same view. I cant seem to figure out how to shrink this element so that it looks more like a button. Please provide examples. Your help is appreciated.
To solve this issue I used a glassbutton with the it's HandleTapped handler as below.
var butt = new GlassButton(new RectangleF(80,150,150,50))
{
Font = UIFont.BoldSystemFontOfSize(22),
NormalColor = UIColor.Red,
};
void HandleTapped (GlassButton obj)
{
}
as for the colors, I used miguel's solution here. Hope this helps someone down the road.

I need to get rid of only the arrow in the navigation bar in Xamarin forms. I tried in but I didn't get a proper solution. please help me overcome this issue. Thanks in advance.
!! I NEED TO REMOVE PERMANENTLY
solutions that I'm tried up to now :
Shell.SetBackButtonBehavior(this, new BackButtonBehavior
{
IsEnabled=false
});
but still, this didn't help me
There is a easy workaround to solve this.
You could override a Icon with a transparent png file(Follow is a transparent png):
and set enabled be false as follows:
Shell.SetBackButtonBehavior(this, new BackButtonBehavior
{
IconOverride = "transparent.png",
IsEnabled = false
}) ;
Then the effect as follows:
Note: You will see that we also can tap that area, therefore we need to set enabled be false.
Based on this official sample to test that.
You can set this using the Xamarin.Forms.NavigationPage class, from within a view's code behind file. E.g. within a ContentPage's constructor.
NavigationPage.SetHasBackButton(this, false);
I have an NSTextBlock subclass that has a specific backgroundColor set. Now when I add a custom paragraph style to a range of text like this
let block = MyTextBlock()
block.backgroundColor = myBackgroundColor
let pstyle = NSMutableParagraphStyle()
pstyle.textBlocks = [block]
attributedText.addAttribute(.paragraphStyle, value: pstyle, range: textRange)
// Append the attributed string to the text views textStorage ...
the text block is shown without a background color. I know that the text blocks works, because rectForLayout gets called, but when I try to override drawBackground it never gets called.
Do I have to do something else for NSTextBlocks to draw their background?
PS: Borders also seem to be ignored. I also tried to find a sample on Github, but that also doesn't draw any backgrounds, despite having a background color set.
After trying everything, I finally managed to get the background to show up, by setting
setValue(100, type: .percentageValueType, for: .width)
It seems that the drawing logic expects some value for the content size. Really nice documentation job there. This requirement is nowhere to be found.
I am trying to create a slider in codename one, but for some reason the slider isn't drawn, other components however, are. The code I have so far
public void start()
{
if (current != null)
{
current.show();
return;
}
mainForm = new Form("Slider and buttons");
c = mainForm.getContentPane();
c.setLayout(new FlowLayout());
Slider jSlider = new Slider();
jSlider.setMaxValue(360);
jSlider.setMinValue(0);
jSlider.setProgress(50);
jSlider.setEditable(true);
jSlider.setPreferredSize(new Dimension(300,50));
c.addComponent(jSlider);
c.repaint();
c.invalidate();
c.revalidate();
mainForm.show();
}
I'm not sure what I could have forgotten, probably just overlooking something..
Thanks in advance
EDIT: It actually does draw the slider if I choose the iPhone skin, but it doesn't do so under "lumia", anyone know why that is?
Its just missing styles under the default Windows Phone theme. Just define the style SliderFull & Slider for both selected/unselected states. We fixed this for the next update.
I have an dojo enhanced grid inside a title pane which inturn in Tabcontainer. I am creating a tab container dynamically and painting the title pane which contains grid. For the first time the grid is painted properly but if i close the tab and again try it to open a tabcontainer title pane is painted but grid inside the titlepane is not painted (or rather its not visible) until i do a browser resize.
So anybody have faced similar kind of issue? Please let me know the solution for this.
I tried resize(), update() & startup() methods on grid nothing worked out.
I am kind of stuck please share your thoughts on this.
Thanks,
Vikram
I had the same problem and found a workaround by doing a dojo connect like:
dojo.connect(Datagrid,"_onFetchComplete",DataGrid,"_resize");
So it should automatically be resized, when DataGrid finished loading data.
Hope I could help.
Greeting, Simon
Have you tried setting an absolute height on the Grid?
Which browsers did you try? (I experienced various problems with DataGrid in TabCointainer using IE)
You must call the TabContainer.layout() each time its container is changing size. For doing this, you could 1) monitor DOMEvents onunderflow and onoverflow on containing DOMNode or 2) when container becomes visible (once-n-forall).
Reason why a window.onresize event fixes it is, that the TabContainer hooks on said event and calls its own layout.
In your situation, where the TabController fiddles with TabContainer's panes, there may be missing a 'layoutChildren' somewhere. Optimally, you should place the grid as the first on only child to tab.
After the grid is deployed, it will take an absolute, calculated height - 'inherited' from the TabContainer. This is fired once the TabContainer chooses to resize or instructed to do so.
Manually, you should be able to implement these lines - after re-opening a tab. The script is taken from _Grid.js to illustrate
var grid = dijit.byId('MYGRIDID');
require(["dijit/layout/utils"], function(layerUtils) {
layoutUtils.layoutChildren(grid.domNode,
grid._contentBox,
[grid.tablist, {
domNode: grid.tablistSpacer,
layoutAlign: titleAlign
}, {
domNode: grid.containerNode,
layoutAlign: "client"
}]);
grid._containerContentBox = layoutUtils.marginBox2contentBox(grid.containerNode,
{
domNode: grid.containerNode,
layoutAlign: "client"
});
// note this line in particular
grid.selectedChildWidget.resize(grid._containerContentBox);
}
My issue
I had a similar situation as yours:
Grid is in a titlepane (closed by default).
Grid can be destroyed and re-created on the fly.
Issue appears when user:
opens the pane.
closes the pane.
re-creates the grid.
re-opens the pane.
grid is not visible, until browser window is resized!
My solution
My approach was to force a resize() on my grid whenever the title pane was being opened.
I used code like this, in a place where I had access to both the grid and the panes:
var titlePane = registry.byId("title-pane-id");
var handle = aspect.after(titlePane, "toggle", function(deferred) {
if (titlePane.open) {
grid.resize();
}
});
The dojo/aspect doc
Don't forget to remove the aspect from your grid if you destroy it.
I did this on dojo v1.8.1
My solution is too easy: define on declaration of grid the bold parameter write here:
grid = new EnhancedGrid({id: 'MyIDgrid',
store: dataStore = new ObjectStore({objectStore: myStore}),
structure: structureGrid,
plugins: pluginGrid,
style : 'width: 725px; height: 350px',
autoWidth : true,
**autoHeight : false,height:'200px',**
elasticView : '2'
}, document.createElement('div'));
this resolve all!
Enjoy!
style="height: auto;" will fit the purpose.
I have two problems with my windows form in Visual Basic .NET 2008. If you have worked with sticky notes you will understand me better.
Now my problems:
If you look you'll see the background color of number 1 and 2 are
diffrent but both belongs to the same control. How is this possible?
In right bottom corner, there is something by which a user can resize the form.
How I can do this?
Item 1: I think you are referring to LinearGradient Brush-- look in the System.Drawing.Drawing2D class.
Item 2: They are drawing a resize handler. You can try using the ControlPaint.DrawSizeGrip method or draw your own.
Update:
Per your comments, you can look into Owner-drawing a Windows.Forms TextBox
You can draw a gradient background by overriding OnPaintBackground():
protected override void OnPaintBackground(PaintEventArgs e)
{
// set these to whatever you want
Color color1 = Color.LightBlue;
Color color2 = Color.DarkBlue;
using (Brush backbrush =
new LinearGradientBrush(e.ClipRectangle, color1, color2,
LinearGradientMode.Vertical))
{
e.Graphics.FillRectangle(backbrush, e.ClipRectangle);
}
}
You can show the size gripper by setting the form's SizeGripStyle to Show:
SizeGripStyle = SizeGripStyle.Show;
Or just set it in the designer.
EDIT: Look at this page for creating a transparent textbox (if the textbox is transparent, the gradient form background will show through.)
