The app contains 4 | two tables: Persons and Addresses. Both have the same functional elements, 5 | so we keep their introduction brief. 6 | 7 | ## Preparing the data model 8 | 9 | The `TableView` uses reflection to determine the information to be displayed 10 | in the table. So, you have to annotate all relevant fields in the 11 | corresponding class as `@TableHeader`: 12 | 13 | ```kotlin 14 | data class Person( 15 | @TableHeader("First Name", 0) 16 | val firstName: String, 17 | @TableHeader("Last Name", 1) 18 | val lastName: String, 19 | @TableHeader("Age", 2) 20 | val age: Int, 21 | @TableHeader("Address", 3) 22 | val address: Address? 23 | ) 24 | ``` 25 | 26 | The annotation requires 2 arguments: The heading of the column to be 27 | displayed in the dialog and an index. The latter is used to sort the table 28 | headers from left to right. 29 | 30 | ## The `TableView` itself 31 | 32 | ![persons.png](screenshots/persons.png) 33 | 34 | The composable `TableView` takes a couple of arguments: 35 | 36 | ```kotlin 37 | @Composable 38 | inline fun TableView( 39 | currentItem: MutableState, // currently selected item 40 | content: MutableState>, // contains all elements to be displayed 41 | indexColumn: Boolean = false, // simple numbering of the table rows 42 | indexColWidth: Dp = 30.dp, // to adjust the index column's width 43 | noinline onRowSelection: (T) -> Unit // execute when selecting a row 44 | ) { 45 | // ... 46 | } 47 | ``` 48 | 49 | Each column of the table can be used to sort the entries descending or 50 | ascending by clicking the column header. **Note that selecting a column for 51 | sorting the last sorting criterion is reset!** 52 | 53 | The search line above the table will filter the table on input by searching 54 | for a match in all columns. 55 | 56 | ## How to embed in your application 57 | 58 | This codes is derived from `TabView.kt`. 59 | 60 | ```kotlin 61 | @Composable 62 | fun TableBody(tableState: MutableState) { 63 | 64 | val person: MutableState = remember { mutableStateOf(null) } 65 | val address: MutableState = remember { mutableStateOf(null) } 66 | 67 | val onPersonSelect: (Person) -> Unit = { 68 | person.value = it 69 | } 70 | 71 | val onAddressSelect: (Address) -> Unit = { 72 | address.value = it 73 | } 74 | 75 | Row { 76 | Column(Modifier.fillMaxWidth(0.7f)) { 77 | when (tableState.value) { 78 | // TableView with index column 79 | SelectionState.PERSONS -> TableView( 80 | person, 81 | mutableStateOf(persons), 82 | true, 83 | onRowSelection = onPersonSelect 84 | ) 85 | 86 | // TableView without index column 87 | SelectionState.ADDRESSES -> TableView( 88 | address, 89 | mutableStateOf(addresses), 90 | onRowSelection = onAddressSelect 91 | ) 92 | } 93 | } 94 | // ... 95 | } 96 | } 97 | ``` 98 | -------------------------------------------------------------------------------- /build.gradle.kts: -------------------------------------------------------------------------------- 1 | import org.jetbrains.compose.desktop.application.dsl.TargetFormat 2 | import org.jetbrains.kotlin.gradle.dsl.JvmTarget 3 | import org.jetbrains.kotlin.gradle.tasks.KotlinJvmCompile 4 | 5 | plugins { 6 | kotlin("jvm") 7 | kotlin("plugin.compose") 8 | id("org.jetbrains.compose") 9 | } 10 | 11 | group = "de.olk90" 12 | version = "0.1" 13 | 14 | repositories { 15 | google() 16 | mavenCentral() 17 | maven("https://maven.pkg.jetbrains.space/public/p/compose/dev") 18 | } 19 | 20 | dependencies { 21 | implementation(compose.desktop.currentOs) 22 | implementation(kotlin("reflect")) 23 | } 24 | 25 | tasks.withType().configureEach { 26 | compilerOptions { 27 | jvmTarget.set(JvmTarget.JVM_21) 28 | freeCompilerArgs.add("-opt-in=kotlin.RequiresOptIn") 29 | } 30 | } 31 | 32 | compose.desktop { 33 | application { 34 | mainClass = "MainKt" 35 | nativeDistributions { 36 | targetFormats(TargetFormat.Dmg, TargetFormat.Msi, TargetFormat.Deb, TargetFormat.Rpm) 37 | packageName = "compose-tableView" 38 | packageVersion = "1.0.0" 39 | } 40 | } 41 | } -------------------------------------------------------------------------------- /gradle.properties: -------------------------------------------------------------------------------- 1 | org.gradle.jvmargs=-Xmx2048m -Dfile.encoding=UTF-8 2 | kotlin.code.style=official 3 | kotlin.version=2.0.21 4 | compose.version=1.7.3 5 | org.gradle.configuration-cache=true 6 | org.gradle.caching=true -------------------------------------------------------------------------------- /gradle/wrapper/gradle-wrapper.properties: -------------------------------------------------------------------------------- 1 | #Sat Sep 21 22:34:35 CEST 2024 2 | distributionBase=GRADLE_USER_HOME 3 | distributionPath=wrapper/dists 4 | distributionUrl=https\://services.gradle.org/distributions/gradle-8.8-bin.zip 5 | zipStoreBase=GRADLE_USER_HOME 6 | zipStorePath=wrapper/dists 7 | -------------------------------------------------------------------------------- /gradlew: -------------------------------------------------------------------------------- 1 | #!/bin/sh 2 | 3 | # 4 | # Copyright © 2015-2021 the original authors. 5 | # 6 | # Licensed under the Apache License, Version 2.0 (the "License");
